specific Embodiment 1

[0071] When using the mining system to check the abnormal status of the electric energy meter, it was found that a certain electric energy meter was faulty, and the data could not be frozen the day before the measurement, resulting in the inability to query the user's daily electricity consumption. The on-site inspection found that the electric energy meter was installed in the corridor. The iron gate was locked, and the staff of the power supply company could not replace the electric energy meter in time. After a day's delay in the replacement, it was found that the data of the old meter was frozen the day before due to a failure. By using the method for complementing the frozen data on missing days of the electric energy meter of the present invention, the missing data can be complemented, and the user's daily power consumption information can be restored accurately and efficiently.

specific Embodiment 2

[0073] An electric energy meter with an accuracy level of 1.0 and a comprehensive multiplier of 1 has lost the daily frozen bottom code data of the electric energy meter on February 3, 2021 due to a chip failure, as shown in Table 1.

[0074] date …… January 31 February 1 February 2 February 3 February 4 Daily frozen bottom code …… 13344 13380 13406 missing 13455

[0075] The missing data can be completed by the method for completing the frozen data of the missing day of the electric energy meter proposed by the present invention, and the specific steps are as follows:

[0076] 1) Obtain user information, energy meter information, daily frozen data of historical dates and characteristic factors related to electricity consumption, as shown in Table 2:

[0077] Table 2 Characteristic map representation of related information of electric energy meter

[0078]

[0079] 2) Concatenate the factors in Table 2 into a vector to form a time series ...

Abstract

The invention discloses a method for complementing frozen data of an electric energy meter in a missing day, belongs to the technical field of power marketing electric quantity monitoring and analysis, relates to a method for complementing the missing data of the electric energy meter, and is particularly used for complementing the missing data of the electric energy meter with the missing data in a certain day or several days. The method comprises the following steps: acquiring user basic information and power utilization related characteristic factors; forming an electric energy data time sequence feature map; dividing into a training set, a verification set and a test set; transmitting the electric energy data time sequence feature map to an input layer of the LSTM network; performing training modeling on the LSTM network by using the training set data to obtain an LSTM model; inputting the verification set into an LSTM model to determine optimal parameters of the model; testing the LSTM model; restoring the data of the date in which the daily frozen data is missing; and outputting a daily frozen data restoration result of the missing date. The data missing is filled, the data quality of the power supply enterprise is improved, the missing data reduction accuracy is improved, and the missing completion precision is high.

Description

technical field [0001] The invention relates to a method for supplementing frozen data on missing days of electric energy meters, which belongs to the technical field of electric power marketing electricity monitoring and analysis, and relates to a method for supplementing missing data of electric energy meters, especially for the missing data of a certain day or several days. The energy meter completes the missing data. Background technique [0002] With the rapid development and extension of smart grids, electric power companies widely use power consumption information collection systems to collect, analyze and process power data collected by smart meters. The importance of power consumption data, especially daily power data, to power users is gradually increasing. . The daily electricity data mainly comes from the electricity consumption information collection system, which is obtained through the smart energy meter (the daily frozen data of the 24 o’clock electric energ...
