摘要
基于RTDS(Real Time Digital Simulator)的动模试验比传统动模试验有很多优点,特别在一些特定故障情况下,可以准确模拟各种期望的系统特性。通过对线路保护装置的动模试验,特别对双回线中一条线故障引起另一条线功率倒向的模拟、TA饱和模拟、CVT(电容式电压互感器)暂态超越现象模拟,可以定量分析和检查保护的各种工况识别能力和保护的动态动作特性。
Dynamic experiment based on RTDS has many advantages over traditional dynamic experiment. Particularly, under special fault conditions, it can accurately simulate all expected system features. Through dynamic experiment on line protection devices, simulation of one transmission line causing power converse to the another in double circuit line, simulation of TA saturation, CVT transient overreach phenomena, we can make quantitative analysis and check-out protection on various condition identification and dynamic movement features for the protection.
