以提高广域继电保护自治性和适应性为目的,引入多Agent技术设计了广域保护系统的体系结构,并给出了广域保护Agent的设计思路.基于分区域分布集中式系统结构,讨论了广域保护子Agent的数据采集、系统通信、故障识别、知识库、结果执行、学习能力等多任务功能描述.利用多Agent系统并行工作与协作机制,构建了广域保护多代理的体系结构和工作机制,并给出了保护功能分解的多代理分层模型.同时结合广域保护功能,阐述了故障识别、结果执行、通信网络性能监视等几种典型子Agent的详细设计特点、结构、模型及其决策过程.通过多Agent在广域保护中的运用,可以有效实现大规模电网系统在不同运行工况下自适应保护.%Based on multi-Agent design solutions of wide area protection (WAP), the hierarchy of WAP is introduced for the purpose of improving the autonomy and adaptability performance of WAP. Based on zone division distribution centralized system structure, the multitask of WAP is discussed, such as data sampling, system communication, fault identification, knowledge base, operation, study function, etc. The system hierarchy and work mechanism are researched, and multi-Agent layered models decomposed by system according to protection functions are built based on parallel work and interoperability of multi-Agent. Meanwhile, the design characteristics, structure, model and decision processing of sub Agent for fault identification, operation, and monitoring of communication are elaborated. WAP can effectively realize adaptability protection for the large-scale power system running in different working conditions in the application of multiple Agents to WAP.
