| 摘 要： | 本文介绍了一种基于ＧＰＳ全球定位系统的异地双端继电保护暂态试验系统，该系统在一条线路的异地两侧就可以同时同步地模拟线路上的区内和区外各种故障，可以更准确地对线路两侧的高频保护进行测试，文中也对该套试验系统在实际现场的测试情况作了介绍。

| Abstract: | This paper presents a two relay testing system at different terminals of a transmission line based on GPS global positioning system to synchronize the clocks of them. The testing system can simulate a variety of internal or external faults on the transmission line, so can test the differential relays of transmission line more accurately. The paper also presents an example of relays test at field. |
