Relay protection based on Multi-Agent System

Agent technology especially Multi-Agent technology is playing a more and more important role in distributed computing technology based on network that is the mainstream computer technology. Agent is a physical or logic entity, including knowledge, thought and goal, it can act on the circumstance and can be acted on by the environment, and can harmonize each other. This paper introduced the concept of Agent and Multi-Agent System with the current lack of the protection technology, discussed the Agent application of relay protection from different standpoints, described the characteristics, structure, model and decision-making process of relay protection based on Multi-Agent System. Today, power system network is more and more intelligent, applying the Multi-Agent technology to the relay protection areas has important significance for improving the stability of the whole system. For this, we built a new structure model for relay protection with Multi-Agent System, and proposed a structural model of Circuit Breaker Agent.
