Apparatus and methods for multi-channel metering

[0002] US 5696501 relates to an electric measuring device and related method. The device has a common node and a number of electrical measuring devices connected to the node. Measuring devices measure power consumption and transmit a signal to the node. The node calculates the power consumed and stores the results in a register.

[0004] US 2005/0137813 relates to a system and method for directly monitoring and calculating energy consumption. The system has a measuring device connected to the power line and a transponder connected to the measuring device. The transponder receives and transmits data from and to the measuring device via a power line and receives and transmits data from and to a remote computer.

Background and substance [0005] According to the invention there is provided a device for multi-channel electricity measurement as described in claim 1.

[0006] One embodiment of the present invention includes a measuring device that is associated with meters from the Quadlogic ASIC family (see US Patent No. 6,947,854 and US Patent Application Publication No. 20,060,036,388). In particular, this embodiment (hereinafter referred to as the "Energy Guardian" for convenience) is a multi-channel meter that is preferably capable of performing many of the functions of the aforementioned family of meters and furthermore provides the abovementioned improvements, features and components.

[0007] Used in at least one embodiment, MiniCloset is a 24-channel measuring device that measures electricity consumption for up to 24 single-phase consumers, 12 two-phase consumers or 8 three-phase consumers. Preferably, one or more Load Control Modules (LCM) are connected to the MiniCloset, discussed below.

[0008] The Energy Guard preferably includes a MiniCloset measuring head module and two LCMs mounted in a steel box. Relays that allow remote disconnection and reconnection of electricity consumers are also mounted in the box, along with current transformers. See FIG. 1.

[0009] Once installed, the electricity supply line to the electricity consumer is output from the main electricity supplier, passed through an Energy Guard device and led directly to the consumer's home. The construction and use of the Energy Guard will be clear to the skilled person after reviewing the following description and related figures. Source code is provided in the attached Annex.

[0011] The Energy Guard meters are preferably capable of providing:

(A) Remote disconnection / reconnection: The meter supports full duplex (bidirectional) communication via power line communication ("PLC") and can be equipped with remotely operated relays (60 amp, 100 amp or 200 amp) allowing remote disconnection and reconnecting electricity users.

(B) Theft Prevention: The system is designed with three specific features to prevent theft. First, the Energy Guard device is preferably installed on an electric pole above the medium voltage lines, making it difficult for consumers to access and manipulate. Secondly, since there are no additional signal cables in the system (ie all communication occurs along the power line), any serious communication cable damage is immediately detected. This means that if the communication cable is cut, the service is cut off, which is easily seen. The third anti-theft feature is that the meter can be used to measure transformer energy to confirm total measurements for individual customers. Discrepancies may indicate energy theft.

(C) Violation Detection: The Energy Guard preferably provides two modes of optical violation detection. Each unit contains light that reflects off a small mirror type sticker. The absence of this reflected light indicates that the box has been opened. Detection of this will automatically disconnect all customers being measured using the Energy Guard unit. In addition, if the Energy Guard enclosure is opened and the surrounding light enters it, this will also automatically disconnect all customers being measured using the Energy Guard unit. These two violation detection modes operate continuously and change many times per second for maximum security.

(D) Reverse voltage detection: In some cases, the supply company may disconnect the energy to an individual customer and the customer will be able to receive energy from an alternative source. If the plant restored the connection under these conditions, the measuring equipment and / or distribution system could be damaged. The Energy Guard is preferably capable of detecting such abnormal conditions. The Energy Guard can detect any voltage that returns to open disconnection with lines connected to the clients' property. If voltage is detected, the Energy Guard firmware will automatically prevent reconnection.

(E) Prepayments: Prepayments for energy can be made by phone, electronic transaction or in person. The quantity of kWh purchased is transmitted to the meter and stored in its memory. The meter will count down energy showing how much available energy is left to reach zero and disconnect. As long as the consumer continues to buy energy, the service will not be cut off and the supply company will have a daily activity report.

(F) Load Limitation: As an alternative to disconnection for non-payment or as part of a prepayment system, an Energy Guard meter may allow the supplier to remotely limit the supplied power at a set level, causing disconnection when the load is exceeded. if

As the consumer exceeds this load and is disconnected, he can reset the button on the optional remote display unit to restore the load, as long as the connected load is less than the set limit. Alternatively, customers can call the electricity provider hotline to restore the service. This feature allows electricity suppliers to provide electricity for critical systems, for example even in the absence of payment by the customer.

(G) Limiting monthly consumption: Some consumers benefit from subsidized rates and are offered maximum monthly consumption. The Energy Guard firmware allows power to be cut off when a certain level of consumption is reached. However, this type of program is best implemented if advanced consumer notification is provided. This can be achieved either by means of a display at home, thanks to which a message or series of messages notifies consumers that their consumption level is approaching the expected monthly consumption. Alternatively (or in combination), you can design temporary service interruptions as the limit approaches, energy is disconnected for longer periods to notify residents. These planned service interruptions act as a warning to consumers about the impending limit so that they have time to change consumer habits.

(H) Meter approval: The integrated system module is preferably replaceable. This allows easy laboratory re-attestation of the meter accuracy in the event of a billing question by the customer.

(I) Working benefits in use: The Energy Guard has built-in numerous event logs and diagnostic functions, providing service technicians with extensive data for commissioning and troubleshooting of electrical and communication systems. Parameters not related to invoicing include: amps, volts, temperature, harmonic content factor, instantaneous watts, wages and volt amps, V2 hrs, 12 hrs, power factor and phase angle.

[0012] These and other features will be apparent to those skilled in the art after reviewing the attached descriptions, program code, and diagrams.

[0013] In one aspect, the invention includes a device for measuring electricity consumption, comprising: means for remote disconnection via power line communications; means for detecting theft of electricity; violation detection means; and reverse voltage detection means.

[0014] According to another embodiment, the invention includes a multi-channel electricity measurement device comprising: (a) a measuring head capable of measuring electricity consumption for numerous electricity consumer lines; (b) a transponder communicating with the measuring head and capable of transmitting data received from the measuring head via power line communication to a remote computer and for transmitting data received via communication with power lines from a remote computer to the measuring head; and (c) a load control module communicating with the measuring head and capable of activating the connection and disconnection of each set of relays, each set of relays corresponding to one of the set of electricity consumer lines.

Detailed Description of Preferred Embodiments [0017] In one embodiment, the Energy Guard measurement device includes MiniCloset (i.e., a measurement device for measuring multiple consumer lines); Scanned Transponder; one or more relays capable of disconnecting the service from selected consumers; Load Control Module; and optical means for detecting adverse effects.

[0018] The MiniCloset and Scanned Transponder cited herein are very similar to those described in US Patent No. 6,947,854. This means that although they have been improved over time, their functions and structures relating to this description can be considered the same as those described in the above patent.

[0019] One aspect of the invention involves utilizing the existing multi-channel measurement function found in MiniCloset and adding remote connection and disconnection via a PLC. The provision of such additional functionality required the addition of new hardware and software. The equipment added includes the Load Control Module (LCM) and connection / disconnection relays. A set of auxiliary circuits has been added to route signal routes to and from the meter's main processor - the MiniCloset5 Measuring Head. Software add-ons include code modules that communicate with the added hardware as described in the following tables.

[0021] FIG. 1 is a block diagram of connections from a preferred embodiment. Medium voltage lines A, B, C, and N (zero) supply Distribution Transformer 110. Low voltage lines connect (via current transformers 120) Distribution Transformer 110 with the Energy Guard unit 140. The Energy Guard unit 140 monitors the current transformers 120 and supplies single-phase Consumer lines 1-24.

[0022] FIG. 2 is a block diagram of the preferred structure of the Energy Guard unit 140.

[0023] The scanned Transponder 210 is the preferred data collector for the unit 140, it can be located outside or inside the MiniCloset device and can also be the main data collector for more than one MiniCloset device. The scanned Transponder 210 preferably: (a) checks the data (each communication preferably begins with the verification of the identity of the clock and meter to ensure data integrity); (b) collects data (it periodically collects a block of data from each meter unit, each block containing previously accumulated meter readings, interval readings and event records); (c) stores data (preferably, the data is stored in non-volatile memory for a specified period of time (e.g. 40 days)); and (d) reports data (via PLC, telephone modem, RS-232 connection or other means).

[0024] The slide plate 280 includes a Minicloset measuring head and a load control module 240 that provides control signals for activating the relays. All electronics are preferably supplied from a 250 power source. Back plate assembly 270 contains a plurality (e.g. 24) Current Transformers and relays - grouped in this example as three sets of 8 CT [Current Transformers] and relays . Consumer cables are routed through CTs and connected to the circuit on consumer property 290. Remotely located Scanned Transponder 210 gains access to the Energy Guard measuring head and communicates bidirectionally using communication on the power line carrier.

[0025] The signal flow shown in FIG. 1 and 2 are preferably obtained by implementing various software code modules that work simultaneously to enable remote connection / disconnection capability in the Minicloset device. These program modules, presented in the Annex below, are:

<td>Code Module</td><td>Location</td><td>Function</td>

<td>Icm.def and pic.def</td><td>Control module load</td><td>Starting connection and disconnecting relays.</td>

<td>pulse.c and pulse.h</td><td>Measuring head</td><td>Establishing communication with LCM.</td>

<td>picend.def and picvars.def</td><td>Measuring head</td><td>Providing control signals to LCM.</td>

EP 1 960 932 B1 [0026] FIG. 3-10 are diagrams of preferred components as described below. Preferred connect / disconnect relays are the K850 series relays, but those skilled in the art will recognize that other relays can be used without departing from the scope of the invention.

[0027] In another embodiment, the implementation of the Energy Guard uses the architecture similarity of traditional chopper panels to a multi-channel measurement environment. In the chopper panel, electricity is supplied to the panel and distributed to various consumer circuits via choppers that provide the ability to connect or disconnect consumer circuits.

[0028] In the MiniCloset / Energy Guard device, numerous current transformers measure current in consumer circuits and return this data back to the central processing unit, where the measurement quantities are calculated. However, MiniCloset / Energy Guard has some key differences to the chopper panel. For example, while the choppers are near the consumer's property, an Energy Guard is usually installed near the supply transformer. The advantages offered by this alternative embodiment will be apparent to those skilled in the art. For example, this embodiment offers improved dimensions and overall size compared to the above discussed embodiments. Space is always a limitation when adding hardware to existing electrical installations. This version of the Energy Guard ("EG") with favorable dimensions of 28 "X 22" X 11 "provides the main advantage in situations of space restrictions.

[0029] The following description includes preferred construction details, detailed schematics and software descriptions. As in the above discussed embodiments, this embodiment is used to provide remote disconnection / reconnection operations, prevent theft, detect misuse, reverse voltage detection, prepay and load reduction, and perform meter attestation.

EG Base Assembly [0032] The EG base comprises a housing bottom with screws and retaining washers as a locking mechanism for the upper EG cover, which is connected on one side by means of sling hinges. See FIG. 11. The bottom of the enclosure provides routing for consumer cables.

EG - Phase Busbars assembly [0033] Three aluminum phase busbars are facing the center of the Energy Guard assembly and staggered. See FIG. 12 and 13. This ensures connection with consumer measuring modules by using transition strips. A stepped busbar arrangement is shown in FIG. 13. Busbars are marked in black.

Zero Strips [0034] EG preferably includes 4 zero strips that form the frame for the EG assembly, whereby a path for zero current is provided. This is shown in FIG. 14. The protrusion on the crossbar ensures neutral current from the transformer of the distribution company. Also, there are 2 neutral strips on the motherboard that transfer neutral current to the control module.

Transition Strips [0035] Transition strips complete the mechanical and electrical connection between consumer measuring modules and phase busbars. See FIG. 15. Transition bars for phase A and C are shown in FIG. 15A; transition strips for phase B are shown in FIG. 15B. FIG. 16 shows transition strips marked in black.

Receiving Module [0036] The receiving module is preferably made of plastic and mechanically adopts measuring modules that can be easily fitted into the EG unit. Each EG has 4 receiving modules, which are combined with each other and can contain either 12 two-phase measuring modules or 8 three-phase. See FIG. 17. The receiving module also provides a mechanical path for the motherboard's zero strip that connects to the control module. See FIG. 18.

Consumer Measuring Modules

EP 1 960 932 B1 [0037] Preferred consumer measuring modules provide the measurements required to measure the consumption of a single-phase, two-phase or three-phase customer. A single module acts as a complete stand-alone meter that can be tested and evaluated as a separate measurement unit. Each module preferably includes an integrated current and relay detection module and electronic measuring components, and provides a connection between the consumer circuit and phase busbars. FIG. 19 shows a preferred integrated current detection and relay module. FIG. 20 is an exploded view of the preferred integrated current detection module and relays.

[0038] FIG. 21 shows exploded views of preferred measurement modules. FIG. 22 shows the measuring modules (marked in black) located in the EG frame assembly and the receiving module.

[0039] FIG. 23 is an exploded view of the Energy Guard, and FIG. 24 is an exploded view of the preferred EG Assembly and EG Basics Assembly.

Electronics [0040] The Control Module boxes preferably contain various PCBs that work simultaneously to collect measurement data from individual measurement modules and communicate on power lines to transmit this data to a host device, such as a Scanned Transponder ("ST").

[0041] FIG. 25 illustrates the preferred Energy Guard system for this embodiment. Each consumer line has a corresponding Measurement Module (PCB 203 and PCB 204, discussed below) (diagrams shown in FIGS. 26 and 27).

[0042] The back plate 2510 shown in FIG. 25 (PCB 234; see FIGURE 28 for a structure diagram) is a common bus that carries signals within the EG. There are two types of possible communication on the Back Board 2510 to enable data transfer from the 2520 Control Module to individual PCB 203 Measuring Modules. This can be achieved either by using the I2C 2-cable option or 1-cable serial option.

[0043] The Control Module 2520 includes a Power Board (PCB 210; see FIGURE 29 for a schematic), which is a power supply board that also has built-in PLC transceiver circuits. The Power Board supplies power to the CPU board and electronic circuit board components 203. The 2520 Control Module also includes an I / O Expansion Board (PCB 230; see FIG. thirty in terms of schematic), which is a board with several I / O extension options that allow communication from the Measurement Modules to the CPU board.

[0044] The Control Module 2520 also includes a CPU Board (PCB 202; see FIGURE 31 for a schematic) that has a built-in Digital Signal Processing (DSP) processor.

[0045] Finally, the Control Module 2520 includes a routing board (PCB 235; see FIGURE 32 for a schematic) with paths and a bushing without any electronic components embedded.

[0046] Each Consumer Display Module (CDM) 2530 is installed in the client's property and can communicate in two directions with the EG installed on the distribution transformer serving the given consumer. Two-way PLC allows communication between the consumer and the supplier on low voltage lines and enables the supplier to send the consumer regular information, warnings, special information about interruptions in supply, etc. [0047] Each CDM 2530 contains the selected combination of measurement and power source together with PLC circuits on the same board (PCB 240; see FIGURE 33 for a schematic). Each CDM also preferably has 99

EP 1 960 932 B1 digital display board (PCB 220; see FIGURE 34 for a schematic). This display communicates with EG and presents consumption information, warnings, notes and other messages from the supplier.

Equipment Implementation [0048] In one embodiment, the Energy Guard has the Fast Fourier Transform (FFT) implemented on the PLC communication signal on both ST and meter, and performs detailed harmonic analysis for measurement purposes. This chapter discusses the implementation scheme of the Measuring Modules, communication with the Control Modules and the PLC communication of the Control Module with the remotely placed Scanned Transponder.

[0049] Control Module 2520 includes a power source and PLC circuits (PCB 210; see FIGS. 25 and 29); I / O extension (PCB 230; see FIG. 30) and a CPU board called Meter D (PCB 202; see FIG. 31). The power source supplies power to the D meter and I / O extension, and includes PLC transceiver circuits. PCB 235 provides route routing and throughput between different boards.

[0050] The Measuring Module can have two versions: 2-phase or 3-phase. The 2-phase version can be programmed by the software to act as a single 2-phase meter or two 1-phase meters. The 2-phase version includes a B2 meter (PCB 203 schematically shown in FIG. 26), while the 3-phase version includes a B3 meter (PCB 204 schematically shown in FIG. 27). Meter B acts as a slave device to the meter D in the 2520 Control Module. The D and B meters can communicate via the serial ASCII protocol. Different B meters are interconnected via BPB 2510 to 2520, which provides power, J Hz standard and serial communication for the D meter. A preferred DSP motor for the B meter is the Freescale 56F8014VFAE chip. The preferred microprocessor used to implement the CPU on the D meter is that of the ColdFire Integrated Microprocessor family, MCF5207. The use of a specific processor is determined by the requirements of RAM and Flash dictated by the meter version. A separate power source and LCD board complete the electronic part of the D meter as a product. In addition to performing the function of the main device relative to B meters, the D meter is also a 3-phase meter and it measures the total output power of the transformer on which the EG is installed. As part of the anti-theft feature, this total value is compared to the total consumption reported by various B meters.

± kWh.

Total transformer output power [0051] The components of the signal streams are as follows:

B2: Two voltage channels, two current channels and no Power Line Carrier Channel (PLC).

B3: Three voltage channels, three current channels and no PLC Channel.

D: Three voltage channels, three current channels and one PLC channel.

[0052] Each stream has an associated circuit for performing analogue amplification and anti-aliasing.

[0053] Characteristic for the D meter is the preferred implementation of:

• Phase Locked Loop (PLL) to block sampling of signal streams for many incoming A / C lines (synchronous sampling per power line).

• Voltage Controlled Oscillator (VCO - Controlled Oscillator) at 90-100 MHz controlled by DSP processor via two PWM modules directly controlling the system clock, thanks to which DSP becomes coherent with PLL.

• a synchronous phase detector that responds only to the fundamental component of the incoming line frequency wave and not to its harmonic components.

• Options for performing FSK and PSK modulation schemes.

[0054] Each measurement and communication channel preferably includes analog front-end circuits followed by signal processing. For analog circuits, a unique anti-aliasing filter with constant gain is assigned, which ensures tracking of the first order temperature, which eliminates the need to re-calibrate meters when temperature changes occur. This will be discussed below, followed by a description of the preferred implementation of signal processing.

Voltage and Current Analog Signal Chain [0055] An analog front-end system for voltage (current) channels includes voltage (current) sensing elements and an adjustable attenuator behind which the anti-aliasing filter is located. The attenuator reduces the level of the incoming signal in such a way that there is no restriction behind the anti-aliasing filter. The constant gain anti-aliasing filter returns the signal to its full value at the input to the Analog-to-Digital Converter (ADC). In the case of measurement, the anti-aliasing filter cuts off frequencies above 5 kHz. The input data is then provided to the ADC, which is part of the DSP. See FIG. 35, which is a block diagram of the preferred analog front-end measurement system.

[0056] While a typical implementation would include a Programmable Gain Amplifier (PGA) followed by a low gain anti-aliasing filter, in the present embodiment an adjustable attenuator followed by a filter is implemented with high constant gain. In addition, the implementation of both anti-aliasing filters on a single chip is the same as using the same Quad Op Amps with 25 ppm resistors and NPO / COG capacitors. This unique implementation by pairing anti-aliasing filters ensures that the phase shifts occurring in both voltage and current channels are completely identical and therefore the accuracy of the power calculations (provided by the product V and I) is not impaired. This provides means for both V and I channels to track temperature changes up to the first row without recalibrating the meter.

[0057] In contrast, when using PGA together with a low gain filter, the phase shift in the V and I signals cannot be monitored due to the temperature. This is because the phase shift introduced by PGA is a gain function.

PLC Voltage, Current and Digital Signal Chain [0058] FIG. 36 is a block diagram of PCB 202; the functions of each block will be obvious to specialists. FIG. 36 presents a favorable implementation for DSP.

[0059] This embodiment preferably uses PLL to block sampling of signal streams for multiple incoming A / C line frequencies. In the above-discussed embodiment, sampling is asynchronous to the power line. In the D meter, there is a 90-100 MHz VCO, which is controlled by a DSP motor via two PWM modules. VCO directly manages the DSP chip clock (deactivating the internal PLL) in such a way that DSP becomes an integral part of the PLL. Locking the DSP system clock relative to the power line makes it easy to match the sampling to the power line waveform. The phase detector should operate to respond only to the fundamental component of the incoming 60 Hz wave, not to its harmonics. FIG. 37 is a diagram of a favorable implementation on DSP.

[0060] The BIOS DSP or voluntary context switching code provides three stacks, each for background, PLC communication and serial communication. The small micro [processor] communicates with DSP using the I2C controller. The circuit integrated with MSP430F2002 measures power sources, tamper detection port, battery temperature and voltage. The tasks of MSP430F2002 include:

i. maintaining RTC;

ii. battery voltage measurement;

iii. temperature measurement;

iv. + U power source measurement;

v. DSP reset in case of reduced energy supply;

vi. providing an additional alarm circuit; and vii. providing a 1-second reference to move to DSP for a time reference for measuring a 1-second reference to a system clock originating from VCO.

D Meter PLC Communication Signal Chain [0061] A typical installation consists of many EG and ST communicating on power lines. Gauge

D communicates in both directions with the Scanned Transponder remotely located via a distribution transformer. To enable this, this embodiment uses the 10-25 kHz band for PLC communication. The PLC signal is sampled at approximately 240 kHz (212 * 60), synchronously with the voltage on the line, and then a finite impulse response (FIR) filter is used to decimate the data.

[0062] See FIG. 38 to view the favorable response of the phase filter to the frequencies and characteristics of the impulse responses.

[0063] After decimation up to 60 kHz (2¹¹ * 30), decimated data is subjected to 2048-point FFT. The data transfer rate is therefore determined as 30 baud depending on the choice of FIR filters. Each FFT produces two bits approximately every 66 msec. when using FIR in the 10-25 kHz band for communication via distribution transformers.

[0064] To circumvent the communication problem in the presence of noise on the line, in the present embodiment it is preferred to implement a unique technique for clear and reliable communication. This is achieved by introducing PLC signals at frequencies that cover the odd half of the harmonics of the frequency lines (60 Hz). This is discussed below for an embodiment using the typical noise spectrum occurring on AC lines in the 12 -12.2 kHz range.

EP 1 960 932 B1 FIG. 39 illustrates the introduction of PLC signals with an odd half of harmonics by 60 Hz. Because the FFT is calculated every 30 Hz and the harmonics are separated by 60 Hz, the data bits are in the range corresponding to 201.5th and 202.5th 60 Hz harmonic in 60 Hz. 39. The algorithm considers these two frequency ranges and compares the signal amplitude in both to determine 1 or 0. This FSK scheme uses two frequencies and gives a data rate of 30 baud. Alternatively, you can implement QFSK, which uses 4 frequencies, for 60 bauds.

[0066] When passing through transformers, both ST and D meters preferably calculate FFT on PLC and data signals every 30 Hz in the range of 10-25 kHZ. Because Phase Coupling Loops (PLL) implemented in both ST and meter D are blocked for lines, data frames are also synchronized with the line frequency (60 Hz). However, data frames may have phase shifts due to:

1. various transformer configurations that may occur on the path between the ST and the meter (delta-Wye, etc.); and

2. phase shift caused by the fact that STs are locked in a certain phase, while single- and multi-phase meters can be powered by other phases.

[0067] The signal-to-noise ratio (SNR) is maximum when the meter data frame and the ST data frames are almost perfectly matched. From the meter's point of view, this requires receiving a PLC signal from all possible STs that it can "hear", decoding the signal, searching for SNRs by comparing data frames and then sending a response to the ST, which gives maximum SNR. FIG. 40 shows 12 possible ways out of phase of the FFT frame received by the meter with the FFT ST frame. The dashed lines correspond to 30 degrees of rotation due to the delta transformer in the signal path between the ST and the meter.

[0068] Furthermore, since data frames are available every 30 Hz on a 60 Hz line, there are two possibilities corresponding to 2 possible phases obtained by dividing 60 Hz by 2. Thus there are 24 ways to incorrectly match meter data frames to ST data frames.

[0069] Each ST frame has an odd integer number of carrier frequency cycles. Because the preferred modulation scheme is Frequency Shift Keying (FSK), if there are n cycles to transmit bit 1, bit 0 is transmitted using n + 2 carrier frequency cycles. For the meter, it is crucial to recognize its own 60 Hz cycles so that it is able to decode its own data bits that are available every 1 / 30th of a second.

[0070] If the meter D decodes signals with incorrectly matched data frames, there is energy that decomposes into adjacent frequencies (separated odd half). If the signal level that falls into the "adjacent" frequency range is lower than the noise level, the signal may be decoded correctly. However, if the spread exceeds the noise level, the ability to distinguish between 1 and 0 decreases and as a result the overall SNR decreases, resulting in a decoding error. Summarizing:

a. If the frames are incorrectly matched, the data bits become unreadable and SNR decreases.

b. When the frequency changes and there are incorrectly matched data frames, there is a substantial amount of energy that scatters into adjacent FFT intervals, which results in colliding with other STs in the system that communicate using frequencies in these specific intervals.

[0071] After determining the clock offset corresponding to the highest SNR, the meter locks until a significant change in the SNR ratio, which the meter registers, in which case the process is repeated.

Implementation of Measurement in Meter D and B using FFT [0072] While versions of Meter B and Meter D perform a measurement, Meter D is also responsible for collecting measurement information from various B meters via PCB 234. Each data stream in the meters has a related circuit for analogue amplification and anti-aliasing. Each section of the analog front-end device has an adjustable attenuator controlled by a higher level code. The data stream is tested at 60 kHz (2¹⁰ * 60), then the FIR filter is used to decimate the data stream up to ~ 15 kHz (2⁸ * 60). Preferred filter specifications are shown in the table below and in FIG. 41.

<td colspan="2">Number of Counts</td><td> 29</td>

<td>blanking attenuation</td><td>bandwidth</td><td>80,453dB</td>

<td>Upper frequency pass</td><td>bandwidth</td><td>3kHz</td>

<td>Lower frequency attenuation</td><td>bandwidth</td><td>12kHz</td>

[0073] Since only data up to 3 kHz are of interest, it is preferable to use a gain drop of 3-12 kHz at a sampling rate of ~ 15kHZ during FIR decimation. Frequencies from 0-3 kHz or 12-15 kHz are mapped to 0-3 kHZ. The real part of FFT is calculated to obtain 2 data streams, which can be further divided into 4 data streams: Real and Imaginary Voltage and Real and Imaginary Current. This is achieved by adding and subtracting positive and negative mirror frequencies for the real and imaginary parts respectively. Since the aliased signal in the 12-15 kHz range falls below 80 dB, accuracy is achieved using the FIR filter discussed above. Alternatively, the 256-point composite FFT can be calculated at each phase of the decimated data stream. This gives 2 pairs of data streams: the real part, which is voltage, and the imaginary part, which is current. This approach requires a complex 256-point FFT every 16.667 milliseconds. [0074] The results of calculating any FFT are the voltage and current shown in FIG. 42, where the notation Vm, n denotes the mth harmonic component of the number of the nth cycle. For example, V11 and I11 correspond to the fundamental component of the first cycle and V21 and I21 correspond to the first harmonic component of the first cycle, etc., as shown in FIG 42, which shows FFT frames for voltage, indicating harmonics. [0075] The real and imaginary parts of the harmonic component of any k-th cycle are given as:

= Re (^) + IIM (K '_t);_in = 1 ... M [0076] The imaginary part of the voltage is a measure of the lack of synchronization between the PLL and the frequency of the lines. To calculate the measured values, the calculations are carried out in the time domain. In the time domain, the FFT function gives you the flexibility to calculate measured values ​​using only the basic one

EP 1 960 932 B1 or with regard to harmonics. When using the complex form of the voltage obtained from FFT, the measured values ​​are calculated as:

Ρ-7 * 7 * ^r tnk tr.k

W = Re (P) - Re (iJ) * Re (/ ") + Im (U) * W-) Var = Im (P) = Re (/"_t) * Im ^) -Re (FJ) * hn (/ ^) PowerFactor -W / P [0077] However, in the formulas above, when harmonics are included (Vmk &amp; Imk; m = 1 ... M, k = 1 ... n), all measurement quantities include results for harmonics. On the other hand, when only the basic component (Vlk &amp; Ilk) was used, all calculated quantities represent only the input from 60 Hz. By way of example, we have presented calculations where only the fundamental component was used to perform the calculations. Of all FFT data frames, only Vl and Il were used. The following values ​​were calculated for a given set of N frames and line frequencies^fline^: kWh = 52 [Re (K,₁) * Re (Z₁₁) + Im (F_at) * Tm (7,_and)]*UNTIL_and * 10 i = l

N kVAr = £ [Rfi (/ ,,) * Im (r ,,) - Re (r_at) * bn (Ai)] * Af, * 10 "r = l

ΑΕ4Α = ΣΚ | * | / "| * Δ /, * 1Ο"; Δί = V_f '/ J h

N , ™ = ΣΚ \ * δ&gt;.

i — l A / _fc pft = zki * δα (= 1 [0078] The power shift factor is shown as:

<img file="PL1960932T4_D0001.tif" />

where W and VA include only the basic components and VAl = VlRMS * IlRMS; where

I, RMS &amp;

<img file="PL1960932T4_D0003.tif" />

for N cycles.

[0079] This flexibility allowing either to include or exclude harmonic components when calculating the measurement quantities translates into a significant improvement over the possibilities offered by the above described embodiment. Another feature offered by this embodiment is the calculation of the Harmonic Content Index (THD). THD is a measure of harmonic distortion that occurs and is defined as the ratio of the sum of the powers of all harmonics to the power of the fundamental component. For the nth cycle, it was rated as:

In one embodiment, the consumer display unit installed at the consumer's residence is a two-way PLC unit that communicates with EG. For example, not only the supplier can send messages, but also the consumer can request verification of consumption using EG installed on the pole. ANNEX [0081]
