摘要
220kV变电站是我国的主要变电系统,而继电保护系统对变电系统的保护和维护起着至关重要的作用。本文以济宁刘屯-唐口220kV变电站为例,介绍继电保护配置的通用设计原则,并从线路保护、母线保护、母联保护、故障录波及网络报文四个方面设计继电器保护系统。该案例的成功应用对同类系统设计有着重要参考价值。
220 kV transformer substation is the main substation system in China,and the relay protection system plays an important role in the protection and maintenance of the substation system.Taking 220 kV Liutun-Tangkou substation of Jining as an example,this paper introduces the general design principles of relay protection configuration,designs the relay protection system from four aspects:line protection,bus protection,bus joint protection,fault recording and network message.The successful application of this case has impor tant reference value for the design of similar systems.
