Embodiment Construction

[0020] specific implementation

[0021] The specific embodiment of the present invention is described in further detail below in conjunction with accompanying drawing:

[0022] Such as figure 1 Shown is a kind of power acquisition data restoration method based on MCMC algorithm, described comprising the steps:

[0023] 1. Obtain user energy information through acquisition terminals (collectors, concentrators, and other data acquisition devices). The information collected includes energy meter identification, data date, data type, data point identification, and energy indication;

[0024] 2. Use the null value judgment function to judge the data null value of the collected electric energy indication. If it is not empty, it will directly store the relevant data. If it is empty, it will perform the null value repair work. By repairing the null value, the power statistics can be improved Accuracy;

[0025] 3. Obtain historical data information related to empty energy meters in ...

Abstract

The invention relates to an MCMC algorithm-based power acquisition data recovery method, and relates to the field of power acquisition data recovery. On the basis of acquired history data, the recovery of power acquisition data empty values can be realized through an MCMC algorithm, and data filling is carried out in a manner of combining multiple algorithms, so that the filled data is relatively high in accuracy, the quantity of requiring for history data is relatively small, the recovery efficiency is relatively high and high reusability is provided. Through the method, missing data can be efficiently and correctly recovered, the accuracy of grid power statistic can be enhanced, and the problems that the realization manner is single, the filled data is relatively low in accuracy and the calculation efficiency is relatively low in the prior art are solved.

Description

technical field [0001] The invention relates to a method for repairing electric power collection data, in particular to a method for repairing electric power collection data based on an MCMC algorithm. Background technique [0002] With the development of the power system, the application of power big data in the power system is becoming more and more extensive, and it has important decision-making support for the strategic deployment of the power system, so stable and accurate power data is particularly important. When the power consumption information collection system collects the electric energy indication information of the user's electric energy meter, due to communication failures, equipment failures, grid fluctuations, and management, etc., a large number of abnormal data (such as null values, sudden increase data values, sudden drop data values, etc.) appear. ), this part of abnormal data will seriously affect the accuracy of power grid electricity statistics, so it...
