Non-intrusive mode electrical load identification system and method

Abstract

The invention discloses a non-intrusive mode electrical load identification system and method. The load identification system comprises electrical load, a load identification terminal and a load monitoring main station; and the load identification terminal performs information interaction with the load monitoring main station through modes of optical fibers, an Ethernet and a wireless public network. The load identification terminal, by analyzing waveform characteristics of current, voltage, active power and the like of typical electrical equipment, defines different characteristic parameters based on a steady state process and a transient state process to establish a standard transient library, and then establishes an electrical load identification model by combination of the steady state and the transient state characteristic similarity of the electrical equipment. The identification system module is high in integration level, the terminal is smaller in size, the construction cost of the system is lower, the running and maintaining of the system are simple without affecting production and life of users; and the non-intrusive mode electrical load identification method can realize accurate identification of load types and running states of multiple paths of electrical equipment at the same time.
