The thesis mainly concerns the following aspects: the relay protection and its trip-close circuit of two circuits transmission-lines are stand alone. The device has the ability of phase-trip that is owns transmission line single phase , 2 or 3phases fault only fault phase tripped.so as to making the power system contact as close as possible. The function of reclosing distribute into relay protection of line and breaker, so it is easy to get no-serious fault information of line protection and realize self-adapted multi pole reclosing. The breaker reclosing depend on the state of owns breaker andthe adjacent breaker. The criterion of serious fault and the sequence reclosing is simple and useful.

本项目具有如下特点：两回线的保护装置及跳、合闸回路完全独立；装置具有分相跳闸功能，即本线单相、两相、三相故障时均只跳故障相，使得故障时系统联系尽可能紧密；重合闸功能合理分配在线路保护和断路器保护中，充分利用了线路保护的信息实现无严重故障判别和分相顺序重合策略的自适应重合功能，由断路器保护根据断路器本身的工作状态和相邻断路器的配合关系实现重合出口；判断严重故障的判据及分相顺序重合闸原理简单合理，具有实用意义，降低了重合于永久故障对系统的冲击。
