[0002] Smart energy meters are essential data acquisition devices for smart grids. They collect, measure, and transmit raw energy data, forming the foundation for information integration, analysis, optimization, and presentation. Smart energy meters are subject to a wide variety of fault types, requiring rapid maintenance by maintenance personnel. However, in practice, the inability of maintenance systems to quickly and accurately identify the specific fault type leads to delayed repairs. Therefore, rapid and accurate fault diagnosis for smart energy meters is crucial for improving maintenance efficiency.

The method comprises: obtaining data curves measured by the smart electricity meter over a preset time period, the data curves comprising multiple cycles of first voltage curves and current curves corresponding to each first voltage curve. A preset number of first voltage curves are extracted from the data curves as target voltage curves, where the target voltage curves correspond to current curves with current amplitudes less than a preset value. Based on the target voltage curves, a target voltage measurement error value for the smart electricity meter is determined. This determines the voltage measurement error value caused by the fault in the smart electricity meter. This error value quantifies the voltage fault condition, thereby determining the fault in the electricity meter. This allows personnel to promptly repair or replace the smart electricity meter, preventing power outages caused by incorrect metering or meter failure.

[0043] The connection module 10 is used to connect the smart energy meter with the single-chip microcomputer and the transmission module 20, and to establish several sensor interfaces for data acquisition.

[0050] Refer to the attached Figure 2 The present invention provides an online early warning method for smart electric energy meter faults, comprising the following steps:

[0051] S1. Obtain the power environment information, fault information, and operation quality information of the smart electricity meter in real time, carry out long-term operation quality monitoring of the equipment, and divide the metering data into levels.

[0052] The smart energy meter is equipped with a connection module 10. This module, connected to the microcontroller and the transmission module 20, has several sensor interfaces for data collection. The microcontroller receives metering data from sensors via the sensor interface and transmits this data to the metering detection module 30 via the transmission module 20. The metering detection module 30 on the microcontroller also receives metering data generated by the smart energy meter via the transmission module 20. The metering detection module 30 periodically reads the smart energy meter and its sensors. Metering data flows from the local smart energy meter and sensors to the metering detection module 30 on the remote microcontroller. The collected metering data includes power environment information, fault information, and operational quality information. By acquiring real-time power environment information, fault information, and operational quality information from the smart energy meter, long-term operational quality monitoring of the equipment can be performed.

[0053] Power environment information includes electrical power, current, voltage, active power, reactive power, apparent power, frequency, power factor, and electricity data; fault information includes the manufacturer, equipment type, service life, equipment status, fault time, and fault cause of the smart electricity meter; operation quality information includes the power supply of the smart electricity meter, actual power consumption, fixed loss, line loss, and the relationship between the measurement errors of each smart electricity meter.

[0054] The data stratification module 40 stratifies metering data based on the transfer relationships between them. It uses the stored standard metering data of smart meters as a reference value for calculating correlations, with the reference value undergoing a dynamic adjustment process. Metering data directly read from smart meters belongs to the first tier. Metering data collected by sensors, if relevant to the smart meter or related to a smart meter failure, belongs to the second tier. Metering data collected by sensors for parameters of upstream and downstream devices of the smart meter belongs to the third tier, and data in the third tier must be linked to the smart meter through data in the second tier. All other data belongs to the fourth tier.

[0055] The MCU processes the received metering data in layers and transmits it to the autonomous processing module 50 via the communication module. The autonomous processing module 50 establishes a self-evolving deep learning network. By introducing disturbance factors and matching algorithms, it optimizes the problem of inaccurate smart meter fault warning results caused by disturbances that cannot be simulated or emulated under complex working conditions. This enables online warning of smart meter faults and the self-evolution of warning technology.

[0056] The beneficial effects of step S1 are: by obtaining the power environment information, fault information, and operation quality information of the smart electricity meter in real time, long-term operation quality monitoring of the equipment is carried out, and the metering data is hierarchically divided according to the transmission relationship between the metering data, which is convenient for mining the association between the data and retaining the data correlation. The smart electricity meter and sensor are collected in proportion using the data correlation method, which will not generate too much duplicate data and reduce the calculation complexity and cost.

[0057] S2. Build a deep learning network with self-evolution capabilities, introduce disturbance factors and matching algorithms, and realize online early warning of smart electricity meter failures and the self-evolution of early warning technology.

[0058] A self-evolving deep learning network is constructed, consisting of an input layer, a mapping layer, an association layer, a perturbation layer, a recurrent layer, and an output layer. The collected metering data is fed into the deep learning network, which then learns through deep training to find the mapping function that defines the input to output from a complex combination of layer-by-layer functions. The network then optimizes the parameters of each layer, reducing errors. Ultimately, the network outputs the level and parameters of abnormal smart meter data, matching the level and parameters to the corresponding fault type and issuing an early warning.

[0059] By comparing the sampled data set with the standard measurement data, the reference value is adaptively adjusted and the initial parameters of the deep learning network are defined according to the reference value. 12 ,ω 23 ,ω 34 ,ω 45 ,ω 56}, the input data of the input layer is Ip 1 ={X1,X2,…,X i ,…,X t}, Among them, X i Represents the measurement data collected at the i-th moment, i∈[1,t], t is the total number of collection moments in the time series segment, represents the mth measurement data collected at the i-th moment, where m is the total number of data collected at each moment. The collected data at each moment is put into a neuron in time series, and the input layer has a total of t neurons. The input layer passes the data to the mapping layer:

[0060] IP 1 =Op 1

[0061] IP 2 =ω 12 Op 1

[0062] Among them, Op1 is the output of the input layer, Ip 2 is the input of the mapping layer, ω 12 is the connection weight between the input layer and the mapping layer.

[0063] The mapping layer maps the input measurement data into the calculation space to facilitate subsequent calculations. The mapping process is as follows:

[0064]

[0065]

[0066] Where c is the coupling coefficient, Op 2 is the output of the mapping layer. The mapping layer passes the data to the association layer:

[0067] IP 3 =ω 23 Op 2

[0068] Among them, IP 3 is the input of the association layer, ω 23 is the connection weight between the mapping layer and the association layer.

[0069] The correlation layer calculates the correlation between data at different levels based on the divided data hierarchy. This correlation includes the correlation between the metering data collected by the sensor and the smart energy meter, as well as the correlation between the metering data collected by the sensor from the upstream and downstream devices of the smart energy meter and the metering data related to the smart energy meter collected by the sensor. The present invention uses a combination of active and passive correlations to calculate the correlation between data at different levels. Active correlation is the setting of correlations for data at different levels based on expert settings or common knowledge; passive correlation is analyzed and calculated using the correlation analysis method constructed by the present invention.

[0070] In each level of measurement data, by analyzing whether each measurement data of the current level and the measurement data to be analyzed show correlation in any time series, the passive correlation coefficient is calculated. The measurement data to be analyzed The correlation is calculated as:

[0071]

[0072] Among them, γ is the correlation analysis evaluation factor. If γ is greater than the preset correlation threshold, it means that there is no correlation between the data. Otherwise, there is correlation. n and n' both represent different levels of measurement data. If there is a correlation between the data, the passive correlation coefficient is calculated:

[0073]

[0074] Among them, δ represents the passive correlation coefficient. The association layer passes the preset active correlation coefficient and passive correlation coefficient to the perturbation layer:

[0075] Op 3 ={Ip 3 ,δ',δ}

[0076] IP 4 =ω 34 Op 3

[0077] Among them, Op 3 is the output of the correlation layer, including management layer input, active correlation coefficient and passive correlation coefficient, Ip 4 is the input of the perturbation layer, ω 34 is the connection weight between the association layer and the perturbation layer.

[0078] The disturbance layer calculates the disturbance factor based on the preset active correlation coefficient and passive correlation coefficient, perturbs the data, and optimizes the problem of inaccurate fault warning results of smart electricity meters caused by disturbances that cannot be simulated and emulated under complex working conditions. The calculation formula of the disturbance factor is:

[0079]

[0080] in, is the disturbance factor, from Randomly selected from . Then the output of the perturbation layer is:

[0081]

[0082] Among them, Op 4 is the output of the perturbation layer, and b is the bias. The perturbation layer passes the data to the recurrent layer:

[0083] IP 5 =ω 45 Op 4

[0084] Among them, IP 5 is the input of the recurrent layer.

[0085] The loop layer selects the learning function in reinforcement learning based on the correlation of the smart meter data in the time series. Taking action a strategy from the current loop state s to reach the next state will produce an impact benefit during the execution of this action. The relationship between the impact benefit and the action strategy is the learning function. The formula of the learning function is:

[0086]

[0087] Among them, Q(s,a) is the learning function, E is the learning process, D is the maximum number of cycles, d∈[1,D], γ is the decay factor used for self-learning control. The closer γ is to 1, the lower the current impact benefit is, and the more emphasis is placed on the value of the subsequent cycle state. The closer γ is to 0, the higher the current impact benefit is. For any action strategy A i Denote by a, for any cycle state S i Indicated by s. The loop layer passes the results of loop learning to the output layer:

[0088] IP 6 =ω 56 Op 5 =ω 56 Q(s,a)

[0089] Among them, IP 6 Represents the input of the output layer, Op 5 represents the output of the recurrent layer, ω 56 Represents the connection weight between the recurrent layer and the output layer.

[0090] After deep learning, a fault mapping model of the smart electricity meter measurement data is fitted. After comparison with the standard value, the real-time error is obtained. The initial parameters are adjusted based on the real-time error so that the final real-time error is within an acceptable range, automatically realizing a dynamic adjustment process.

[0091] Based on the output metering data fault mapping model, the data anomaly level and its anomaly parameters are obtained. The matching module 60 can preset the fault types corresponding to different data anomaly levels and anomaly parameters according to the actual situation, thereby matching the fault type of the current data, and the online warning module 70 issues a warning signal.

[0092] The beneficial effects of step S2 are: establishing a deep learning network with self-evolution capability, using big data modeling and analysis as a means, fitting a smart electricity meter metering data fault mapping model through the input layer, mapping layer, association layer, disturbance layer, loop layer and output layer, making a reasonable arrangement based on the correlation between the smart electricity meter metering data, introducing disturbance factor matching and algorithms, optimizing the problem of inaccurate warning results caused by disturbances of factors that cannot be simulated and emulated under complex working conditions, and realizing online warning of smart electricity meter faults and the self-evolution of warning technology.
