Abstract

The invention belongs to the data processing technical field of the electrical energy in a power system and particularly relates to a method for automatically processing the missing value of the electrical energy. The method comprises the steps of identifying collected data during the metering process of an ammeter, recognizing and positioning a missing value in a sequence, storing the subscript of an identified null in the vacancy set of the electrical energy among the historical data of the traversal measurement points of the ammeter, and predicting the missing value of the electrical energy based on an optimized local weighted polynomial fitting model. According to the technical scheme of the invention, the missing value of the electrical energy can be processed more accurately. Meanwhile, based on the adaptive prediction for different data distribution, the electrical energy data of a remote electrical energy metering and managing system can be better managed and utilized.

Description

technical field [0001] The invention belongs to the technical field of power system electric energy data processing, and in particular relates to a method for automatically processing missing electric energy values. Background technique [0002] The problem of missing electric energy data can be formalized as the problem of automatic interpolation of missing data. At present, common missing value processing methods include mean substitution, regression, and missing indicator variable models. Among them, the methods and ideas of regression filling and interpolation have been deepened and expanded by many researchers. [0003] Li Xuying. Missing value interpolation method based on spatial autoregressive model[J]. Mathematical Statistics and Management, 2005, 24(3): 45-50, research on the imputation of missing values ​​in cross-sectional data from regions, discussed When there is spatial correlation in the data, the establishment of spatial autoregressive model and the method...
