The Research of Relay Protection System Based on Multi-Agent

Though the research of relay protection of power system has already passed certain period, but at present, the relay protection of power system still exists some problem such that the mend time is too long, regular protection value can´t meet dynamic change of system, the detection means of trouble is limited and the judgment and location of trouble is difficult, etc. In order to solve these problems well, this paper introduces Multi-Agent theories in the research of relay protection, has set up a kind of relay protection system based on multi-agent. In this system, it has been improved that the dependability and swift of movements of detection, protection, trouble diagnosing greatly through fully utilizing the good intelligent of Agent; The good communication harmony of multi-agent, raise the fault-tolerant ability of protection system, well prevent protection to refuse to move and move by mistake, accelerate the speed of protecting movements.
