| 摘 要： | 在介绍输电线全球卫生定位系统（GPS）行波故障定位原理以及RTDS并行处理和实时输出等特点的基础上，详细分析了电力系统实时数字仿真器（RTDS）行波线路模型的算法。通过用RTDS仿真一个小型的500kV环网，并在其线路上设置各种特征故障的方式，来测试输电线路行波故障定位装置的性能并用高速采样分析纪录仪对测试中的波形记录和误差进行分析。模拟试验表明：用RTDS对此故障定位装置进行试验是一种较好的方法。

| Abstract: | On the basis of describing the principle of fault location with GPS and the char acteristics of parallel processing and real-time output of RTDS, the a lgorithm of travelling wave model of transmission line of RTDS is analyzed in de tail. Through the simulation of a small 500kV ring network by RTDS and setting f aults of various characters on it, the travelling wave based fault location devi ce for transmission line is tested and both its waveform and location error are recorded and analyzed by a high speed sampling analyzer. Simulation results show that it is a good method to test this device by RTDS. |
