关于220kV线路保护配合的探讨

Discussion on 220 kV line protection coordination

线路保护是电力系统中不可缺少的装置,对维护变电站电力系统安全有着重要的作用。随着社会电力运行负荷的大幅度增加,对变电站采取综合性的线路保护是电力企业必须要深入研究的问题。线路保护功能的发挥要依赖于各种装置产品的运行,只有按照设计线路的标准要求组合装置且进行模式调试后,才能将线路保护投入到正常的系统使用中。针对这一点,文章以实际案例为研究对象,分析了220 kV线路保护配置的相关问题。

Line protection is an indispensable device in power system,and the maintenance of substation power systemsecurity plays an important role.Alongwith the social power systemload increases substantially,the substation adopt integrated circuit protection of electric power enterprise needs in-depth study of the problem.Circuit protection function depends on a device production run,only in accordance with the design of circuits standard combination device and mode for debugging,can be input to the use of normal line protection system.In viewof this,based on the actual case as the research object,this paper analyzes the related problems of 220 kV line protection configuration.
