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。
On the basis of immune algorithm based wide-area protection fault identification,ahierarchically wide-a rea backup protective system is proposed.According to different functions andscope of the wide-area protection,the system is divided into measurement and monitoring layer,regionaldecision-making layer and system monitoring layer.In this paper,improved immune algorithm is used toachieve 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.
