摘　　要：以提高广域保护应对系统故障时出现的通信误码、保护失灵和断路器失灵等复杂运行情况的能力为目的,结合故障识别算法,提出了广域保护多Agent系统的动态协作机制。基于分区域分布集中式多Agent广域保护系统结构,结合多信息融合的广域故障识别保护算法,研究广域保护主站和子站,子站与子站间的信息动态协作机制,详述了保护系统对故障识别、容错处理和执行处理等动态协作机制的处理过程,并利用状态机描述多Agent系统的整体协作机制。基于IEEE 39节点系统的算例分析描述了通信错误、保护失灵和断路器失灵等几种典型故障时多Agent间的协作过程。Based on fault identification algorithm and zone division distribution centralized system structure of wide area protection （WAP）, the dynamic cooperation mechanism of WAP based on multi-Agent is introduced for the purpose of the improvement of WAP performance to overcome the condition of communication bit error, protection failure, breaker failure, etc. On the basis of distribution centralized system structure based on multi-Agent, the dynamic information cooperation rules are researched between main station and substation, substation and other substation with the multi-information fusion based fault identification algorithm of W AP. And the W AP cooperation processing is elaborated, including fault identification, fusion handles, operation handles, etc. Meanwhile, the whole cooperation mechanism is described by state machine. The example analysis on IEEE 39 nodes system shows the concrete cooperation processing of sub agent in some case of typical faults.
