摘要本文在分层次保护结构的基础上,提出一种基于免疫算法的分层次广域保护系统。根据功能和范围不同,将系统分为测量与监控层、区域决策层和系统监控层3个层面。文章对免疫算法进行了改进,实现了系统监控层面疑似故障点的快速定位,并提出了基于免疫算法的分层次系统决策方案。最后通过大量仿真算例对比传统结构的保护算法,该系统在系统监控层上保证了故障识别的准确性,同时有更高的计算效率和更加合理的算法流程。

Abstract：On the basis of immune algorithm based wide-area protection fault identification, a hierarchically wide-area backup protective system is proposed. According to different functions and scope of the wide-area protection, the system is divided into measurement and monitoring layer, regional decision-making layer and system monitoring layer. In this paper, improved immune algorithm is used to achieve the fast fault location of the suspected fault point in the system monitoring level, and proposed a hierarchical system decision-making scheme based on immune algorithm. Compared with the conventional structure protection algorithm, case study demonstrates the efficiency and consistency of hierarchically wide-area protective system.
