摘　　要：分析基于广域信息的后备保护的主要保护原理,包括:广域电流差动保护、基于广域信息的自适应保护、基于专家系统的广域后备保护、基于潮流转移识别的广域后备保护以及基于复杂网络原理的广域后备保护。简单说明了各种广域后备保护优缺点。基于广域信息的后备保护已成为目前研究的热点,随着智能电网的不断发展,广域后备保护技术将会得到不断的改善。This paper analyzes the main protection principle of backup protection based on wide area information, inclu- ding wide-area current differential protection, wide-area information based adaptive protection, wide-area backup protec- tion based on expert system, wide area backup protection based on flow Transferring relativity factor and wide area back- up protection based on complex network theory. This paper briefly explains the advantages and the disadvantages of a va- riety of wide-area backup protection. Wide Area Information-based backup protection has become a hot topic at present, with the continuous development of smart grid, wide-area backup protection technology will continue to improve.
