摘要
详细说明了电力设备或线路的负荷(功率)方向选择元件的原理,分别对相间功率方向、零序功率方向和负序功率方向保护带负荷校验方法进行了详尽的阐述。对不同的方向保护的试验方案和试验结果加以分析,使得安装调试、运行维护人员对不同的方向元件保护的调试方法和试验结果有个正确认识,确保电力系统安全运行。
This paper introduces the theory of the load power directional element choice of the power equipment or lines,gives a detailed explanation of on-load test method applied to inter-phase power direction protection,zero-sequence power direction protection and negative-sequence power direction protection,and analyzes the experimental projects and results in different directional protection,which enable the installation operation and maintenance personnel to have a correct understanding of different debugging methods and experimental results and ensure the safe operation of power system.
