基于智能多代理技术的广域电网协调保护系统

结合智能多代理系统(multi-agent system，MAS)的技术特点，提出建立基于MAS的广域电网保护协调系统。该系统的保护代理模型采用慎思型的理性智能体(BDI)结构，各代理间通信采用知识提取及操控语言(KQML)，实现了各保护代理间的信息交换和协调配合。文章以差动保护为例，重点阐述了主、后备保护区的动态划分，提出了保护动作规则和协调机制，提高了保护系统对电网结构变化的灵活适应能力。

A MAS-Based Coordinated Protection System for Wide Area Power Network

Combining with the technical features of multi-agent system(MAS),in this paper it is proposed to build a MAS-based coordination system for the protection of wide area power network in which the deliberation architecture of belief desire-intention(BDI) is applied to the agent models of this coordinated protection system and the knowledge query and manipulation language(KQML) is adopted to the communication among the agents to realize the information exchange and coordination among the agents.Taking the differential protection for example,the dynamic partitioning of its main and backup protection zones is emphatically expounded,the action rules of protection and coordination mechanism are put forward,thus the flexible adaptability of protection system to the structural changes of large-scale power network is enhanced.
