Research of relay protection setting calculation system for power plant based on Multi-agent

At present, relay protection setting calculation system for power plant has been applied in power plant. It helps people complete relay setting calculation. But there are some problems in the relay protection setting calculation system. For example, it is difficult to update knowledge and can not automatically acquire new knowledge. So the intelligence of the systems is limited. This paper introduces multi-agent into the field of relay protection setting calculation system for power plant. The multi-agent system connects agents which run in different power plants and forms an intelligent system in which each agent can work independently, cooperate and share knowledge with other agents. Agents can be layered and classified through knowledge being shared and verified. After the real-time data of the plants is introduced into relay protection setting calculation system, multi-agent system can use data mining to discover new knowledge. It can greatly improve the intelligence of relay protection setting calculation system.
