Description
Technical Field
The invention relates to the field of power systems, in particular to a diagnosis method based on electric energy meter flying and a high-speed power line carrier (HPLC) module.
Background
Along with the vigorous construction of a strong smart grid, the coverage rate of the smart electric meter is continuously improved, and the original mechanical electric energy meter is basically replaced. According to statistics, the nationwide automatic meter reading system based on the power line carrier covers more than 5 hundred million intelligent electric meters, and the voltage, current, power, electric energy and other data information of the electric energy meters can be easily obtained through the automatic meter reading system.
The electric energy meter is a legal measuring tool for electric power commodities, and the collected electric energy information is a main basis for electric power transaction settlement between an electric power company and users, power generation enterprises and other comprehensive energy service companies. Therefore, the metering accuracy of the electric energy meter receives high attention of all parties, and is also a main supervision object of the metering administrative department in China. The electronic intelligent electric meter has the advantages of high precision, wide frequency band, strong overload capacity and low energy consumption, has more advantages than an induction electric meter, not only has the function of electricity metering, but also has the functions of data storage, charge control, remote switching on and off, data communication and self-diagnosis expansion. However, since there are many components inside the smart meter, it is very sensitive to external interference, and when the field environment is complex, disturbance factors such as external temperature, humidity or thermal shock, rated sinusoidal vibration, electromagnetic interference may cause the electric energy meter to malfunction or even fail. Stopping, flying and reversing the electric energy meter are typical representatives of metering abnormality of the intelligent electric meter, and are happened generally, but metering misalignment caused by the abnormality often causes customer doubt, influences customer service quality, and causes a power company to suffer from serious trust crisis and economic loss. How to monitor the running intelligent electric meter in real time and accurately find and eliminate faults in time is a problem which is urgently needed to be solved by power companies.
The collected data of the electric energy meter for stopping, flying and reversing judgment is mainly the indication value of frozen active electric energy. The electric energy meter freezing data is typical time sequence data, and the data are collected in time sequence and describe the change of daily electricity quantity along with time. There are many types of abnormal points in the time series, and the abnormal points can be generally classified into 2 types according to the influence generated by the abnormal points, namely additive abnormal points and innovation abnormal points. An additive anomaly is generally an isolated anomaly that does not propagate to subsequent observations. The innovation exception point usually relates to the related structure in the time sequence, so that the innovation exception point often appears in pieces, and when a fault point appears, the follow-up point of the fault point also shows a certain exception due to the relevance.
An additive anomaly is an isolated anomaly, as shown in fig. 1, in which data collected during a certain period of time undergoes a large pulse change and then returns to normal quickly. The abnormal data do not reach subsequent observed values, but affect data such as freezing of the smart meter.
The type I innovation anomaly point shows that the data generates a large step at a certain moment and then starts to work stably, and all the subsequent points of the data show anomalies due to the correlation, as shown in fig. 2. Such anomalies have a large influence on the metering of the electric energy meter, and even cause billing disputes.
Type II innovation anomaly is another form of innovation anomaly, as shown in fig. 3. It is shown that the data trend produces a sudden change at a certain time and stabilizes the work. Such an abnormality is difficult to judge, errors accumulate on a time sequence, and the influence on subsequent electric energy meter measurement is the largest.

The HPLC module is generally provided with a built-in carrier and a main control chip, and has certain calculation and processing capabilities. The operation of the HPLC module is independent of the electric energy meter, is the best carrier for measuring, detecting and monitoring the normal operation of the electric energy meter, and is developed based on the advanced application of the HPLC module such as power failure reporting, low voltage detection, station area identification and the like. The invention also provides a high-speed power line carrier module based on the diagnosis of the flying of the electric energy meter, wherein the center distance abnormal point diagnosis algorithm is embedded into a main control chip of an HPLC module in a software mode, and the HPLC module automatically acquires the operation data of the electric energy meter and carries out the diagnosis of the metering abnormal point.

step 1: and reading the curve data of the metering points at the moment i. The frozen electric quantity data of the electric energy meter is read regularly every day through an HPLC module.

and step 3: calculating the measurement deviation degree of n measurement data points
Degree of measurement point deviation at point j:
and 4, step 4: when measuring the degree of deviation
And m is a measurement abnormity judgment threshold, wherein m is 2, corresponding time information is marked, and measurement point flying abnormity information is output.
The method comprises the steps of diagnosing and simulating abnormal point data of the time-series electric energy meter by using a central distance abnormal point detection algorithm, injecting additive abnormal points, I-type innovation abnormal points and II-type innovation abnormal points into j-28 respectively, and performing a fault simulation result, wherein the simulation result is shown in figures 5-7. Deviation detection represents the best judgment of such data anomalies, with the gauge point deviation approaching 200 at position 28, much greater than 1. For the type I innovation abnormal point, the deviation degree algorithm also shows good judgment capability. The measurement points at the positions of the series 28 deviate by 100 degrees, which is also much greater than 1. The simulation result of the II type innovation abnormal point shows the good judgment of the deviation degree algorithm, and the center distance of the abnormal point at the beginning of the sequence 28 is nearly 4 times higher than that of the normal metering point.
