摘要
电网要求继电保护有可靠性、选择性、快速性和灵敏性四项基本性能,需要整定人员针对不同的使用条件,分别进行协调。文中对关于引起220 kV线路后备保护失配的原因、各种目前常用保护装置的各项定值如何整定才能使保护的动作行为更符合电网的安全运行需要等问题,作了一些探讨和分析,以供同行们参考。
Power network requires that protective relaying should be reliable, selective, speeding, and sensitive. People engage in it need to coordinate separately under different circumstances. The paper discusses the cause of backup protection on 220kV power line losing coordination and how to set kinds of protective equipment now used in Guangdong power network, in order to make them operating safely in accord with demands of power network.
