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 50 0 k V环网 ,在其线路上设置各种特征故障 ,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器分析其误差。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效果。模拟试验表明 ,用RTDS对该装置进行试验是一种较好的方法。
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.
