本文主要研究如何合理利用计算机人工智能多代理(Multi-Agent)技术,来解决大电力系统中不断出现的因保护配合不当、保护动作不能及时或失误等复杂问题,分别实现了保护在正常运行、失去局部或全部对侧信息的情况下,能适时的、有效地实现保护间的协调,从而克服了单智能Agent 只能解决和处理单一的、小范围信息的困难,加强了各智能保护Agent 之间的通信和协调,提高大电力系统的稳定性和可靠性,促进大区域电网联网的进程。 关键词: 人工智能多代理技术 大电力系统 保护协调 Abstract: This paper studies mainly how to make use of Multi-Agent technology to solve the complex problems which are caused by unsuitable coordination between protection and untimely action and protection fault activity in large power system, and realizes timely the coordination among protections effectively in when losing some or all information. Thus it overcomes the difficult of solving single or shore range information, enhances correspond and coordination among the intelligent protect Agent, raises the stable and reliable property, and promotes the process of power network for large area. Key Words: Artificial intelligence, Multi-Agent technology, Large power system, Protection coordination
