Abstract

The invention provides an electric quantity data recovery method and device. The method comprises the steps that the source data of initial data is preprocessed, abnormal data is obtained, wherein the abnormal data comprises at least one electricity customer identification and electric quantity data corresponding to the at least one electricity customer identification, the electric quantity data contains electricity consumption dates and daily electricity consumptions corresponding to the electricity consumption dates, and each daily electricity consumption is a normal daily electricity consumption or an abnormal daily electricity consumption; for each electricity customer identification, the corresponding electric quantity data is subjected to period division, and the electric quantity data in at least one cycle is obtained; when the electric quantity data in the at least one cycle is not one, the electric quantity of each abnormal daily electricity consumption in the first cycle is determined; according to the electric quantity, adjacent to the electric quantity data in the first cycle, in other cycles, the abnormal daily electricity consumption is recovered. Based on the electric quantity data recovery method, the abnormal data is analyzed and recovered through the data periodicity, and as the recovered data can meet the change rule of real data, the accuracy of the recovery result can be higher.

Description

technical field [0001] The invention relates to the field of electric power technology, and more specifically, to a method and device for restoring power data. Background technique [0002] With the reform of the power system, electricity sales companies will use the existing electricity data to predict the electricity sales in the next month. Therefore, the integrity of the electricity data directly affects the accuracy of the forecast results. In fact, the power data will be lost, incomplete or incomplete due to various reasons. [0003] At present, the commonly used power data restoration methods mainly include the adjacent unit average method and the adjacent unit numerical method, and the repair results are only related to the power data in the adjacent units. However, due to the large difference in the power data of electricity customers in different periods, the accuracy of the restoration results calculated by using the power data of adjacent units is very low.
