基于Agent的变电站通信研究

Research on Substation Communication Based on Agent

多智能体(Agent)系统能有效解决分布式问题,电力系统属于分布式结构。文章以智能变电站为研究对象,将Agent技术与IEC 61850标准相结合,分析了Agent技术解决IEC 61850通信时可能的通信对象冲突问题。将IED设备作为Agent,在相同局域网内通过实现多Agent自治算法协调系统,设置消息过滤和创建轮询Agent,来避免通信的混乱;在不同局域网间依靠TCP/IP协议传输消息,解决了变电站复杂的分布式通信问题。

The multi-Agent system can effectively solve distribution problems,and the electric power system belongs to the distributed structure.This paper takes the intelligent substation as the research object,combines the Agent technology with IEC61850 standard,and analyzes how the Agent technology is used to solve the possible conflicts of IEC61850 communication.In the same LAN,IED device is used as Agent to avoid communication confusion by implementing multi-Agent autonomous algorithm coordination system,setting message filtering and creating polling Agent.Between different LANs,the complex distributed communication problem of substation is solved by using TCP/IP protocol to transmit messages,which has high practical value.
