当前,国内外有许多学者对广域保护进行了研究,并取得了相当可观的理论研究成果。主要对已提出的广域后备保护算法进行了整理和综述,包括:在线自适应整定、电气信息、状态信息的算法,并分析其存在的优缺点。论述了在IEC61850标准的基础上,构建广域后备保护通信系统。基于这些理论前提下,给出了作者自己的看法。
This paper has wide area backup protection algorithm for the sorting and review,including:the wide-area backup protection algorithm which is about information online adaptive setting,which is based on the electric parameters and the quantity of state information.Meanwhile,it analyzes its advantages and disadvantages.Then,it discusses the wide area backup protection communication system that is based on IEC 61850.
