摘　　要：在实验室环境中创造真实的卫星接收条件存在很多困难，卫星模拟器可以代替卫星接收机模拟出卫星信号。从理论上分析了卫星模拟器代替卫星接收机进行实验检测的优势，分别以不同的时间同步输出信号为基准，测试比对卫星接收机与卫星模拟器在电力时间同步系统检测中的时间精度，二者差值为10-15 ns，实验结果表明电力系统时间同步检测中，在考虑卫星模拟器带来误差的前提下，卫星模拟器可以代替卫星接收机完成实验检测。It is very difficult to establish a real satellite receiver in laboratory environment. The satellite simulator has ability to replace satellite receiver in simulating satellite signals. Advantages of satellite simulator in time synchronization detection are analyzed. Based on different time synchronization output signals, time difference is about 10-15 ns according to comparison results between satellite receiver and satellite simulator in power system time synchronization detection. With consideration of error margin caused by satellite simulator, satellite simulator can replace satellite receiver in power system time synchronization detection experiment.
