| 摘 要： | 针对输电线路行波故障定位装置的测试问题，利用ＲＴＤＳ仿真一个小型的５００ｋＶ环网，在其线路上设备各种特征故障，来测试输电线路行波故障定位装置的性能，并结合高精度测量仪分析其误差，在分析误差的基础上，结合ＲＴＤＳ的计算步长和Ｄ／Ａ转换时间等，总结出一种提高ＲＴＤＳ波形精度的补偿算法，输入补偿算法后的数据，获得了较理想的仿真结果。模拟试验表明，用ＲＴＤＳ对该装置进行试验是一种较好的方法。

| Abstract: | A sm all5 0 0 k V loop network has been simulated,with help of RTDS to test travelling wave based fault location devices for transm ission lines. Performances of the devices are tested through different characteristic faults on the transmission lines,and whose errors are analyzed with high- precision m easuring instruments.Based on analysis of errors, this paper further studies the calculating step and D/A converting time of RTDS and then proposes a compensation algorithm for improving wave- precision of RTDS. Satisfactory simulation results have been obtained when the input data are com pensated,which shows that it is a better way to test the device by use of RTDS. |
