Abstract

The invention relates to an electrical load identification method and apparatus. The method comprises the steps of obtaining a separation signal of a current signal at a load power supply inlet; and determining the current working state of the load by using the separation signal of the current signal at the load power supply inlet. According to the technical scheme, a separation signal of a current signal at a load power supply inlet is obtained by using a self-adaptive single-channel blind source separation algorithm; and the working state of the single load is determined by utilizing a residual error between a separation signal of a current signal at the load power supply inlet and an output signal of the pre-established recursive least square identification model corresponding to the single load. The defect that most separation algorithms select useful information according to experience is overcome, the calculated amount is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of electric load identification, in particular to an electric load identification method and device. Background technique [0002] As an important part of smart grid construction, power demand side management is an important means to realize reasonable energy saving in the whole society. Demand side management includes energy efficiency management, load management, fuel substitution and energy conservation, etc. As one of the key technologies of load management, home appliance load identification can monitor the usage of various home appliances online and realize the classification and measurement of electricity charges. This not only allows users to know their electricity consumption in a timely manner, guides users to consciously take energy-saving measures, and reduces electricity bills, but also helps power companies understand the load composition of users, realize real-time interaction with users, and...
