摘　　要：对一次新设备启动送电过程中空载及轻载线路继电保护向量测试工作遇到的问题进行了讨论,对解决方法进行综合论述分析,提出了新设备启动过程中带负荷测向量的注意事项,并在此基础上提出了新的测试方法。新方法不仅解决了大多数空载及轻载线路保护向量无法测试的缺点,同时大大缩短了测试时间,确保了电网的安全稳定运行。The problems occurring in the relay protection vector testing for no - load and light - load lines during the startup of new power transmission equipment are discussed, the comprehensive solutions are analyzed, the points needing attention in the process of vector testing with load for new equipment startup are proposed, and a new testing method is put forward on this ba- sis. The new method not only improves the shortcomings that the protection vector cannot be tested in most no - load and light - load lines, but also significantly reduces the testing time, which ensures the safe and stable operation of power grid.
