Abstract

The invention discloses a user missing data filling method, device and equipment, and the method comprises the steps: extracting power data from a to-be-filled original power data matrix through a preset sliding time window, so as to form a time window data matrix; based on an interpolation algorithm, pre-filling missing data in the time window data matrix to obtain a pre-filled matrix; determining a first user in the pre-filling matrix, wherein the first user is a target user with missing power data; for each first user, searching multiple second users similar to the power data of the first user in the pre-filling matrix, enabling the power data of the first user and the power data of the multiple second users to form a similar matrix corresponding to the first user, and based on a singular value threshold algorithm, determining the filling value of the missing data of the first user in the similar matrix corresponding to the first user, and filling the filling value into the corresponding position in the original power data matrix, so that the filling precision of the missing data of the user can be improved.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a method, device and equipment for filling missing user data. Background technique [0002] With the continuous advancement of energy Internet construction and the rapid development of smart grid technology, the requirements for storage, analysis and mining of power data on the distribution network side are also increasing. In the actual collection and transmission process of the power grid, during the collection, transmission, and storage of power user data, due to machine perception equipment failures, transmission network delays, storage and processing errors, etc., there will usually be data loss, which will further seriously affect the later stage. Analysis, mining and modeling of power data. [0003] The traditional missing data filling method is based on the local characteristics of the data, such as linear interpolation, which is easily disturbed by noise and abn...
