Abstract

An embodiment of the invention discloses a method and system for reconstructing power signals based on a prediction matrix, and the method comprises the following steps of step 1, inputting a measuredpower signal sequence S; and step 2, performing data reconstruction on the power signal sequence S, wherein the reconstructed power signal sequence is SNEW, and specifically SNEW=W*SSEG, wherein W represents the prediction matrix, W* represents a pseudo-inverse of the prediction matrix, and SSEG represents a set of segment sequences.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a power signal reconstruction method and system. Background technique [0002] With the development of smart grid, the analysis of household electricity load becomes more and more important. Through the analysis of electricity load, household users can obtain the electricity consumption information of each electrical appliance in a timely manner, as well as a detailed list of electricity charges; the power department can obtain more detailed user electricity consumption information, and can improve the accuracy of electricity load forecasting, Provide a basis for overall planning for the power sector. At the same time, using the electricity consumption information of each appliance, the user's electricity consumption behavior can be known, which is of guiding significance for household energy consumption assessment and research on energy-saving strategies. [0003] At present, the...
