摘　　要：数据采样的正确与否直接影响继电保护装置的动作可靠性。文章基于某500 kV线路保护装置改造工程,利用分布电容的容性负荷特征,提出了线路启动送电时的带负荷相量测试方法,验证了保护装置数据采样的正确性,保障了电网的安全稳定运行。The correctness of data sampling directly affects the reliability of relay protection devices.Based on the renovation project of a 500 kV line protection device,this paper uses the capacitive load characteristics of distributed capacitance and proposes the phasor test with load at start-up of power transmission,which verifies the correctness of the data sampling of the protection device and ensures the safe and stable operation of the power grid.
