摘要
随着微机保护技术和光纤通信技术的日益成熟 ,分相电流差动保护逐渐成为高压线路的主保护 ,其保护原理简单 ,有明确的选择性 ;但通信技术是差动保护的一个关键技术。线路分相电流差动保护的现场对调一直是困绕技术人员的问题 ,数字式分相电流差动保护的辅助功能为现场使用带来了很大方便。
Along with the progress of the microcomputer protection technology and optic fiber communication technology,line differential protection is changing as main protection of HVAC transmission line.It's of simple principle and of clear selection.The communication is a key technology of line differential protection.Site test is always a problem for the line differential protection.The auxiliary function of the line differential protection is very convenient for site application.
