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,在某些故障情况下,可准确模拟各种期望的系统特性。通过对母线保护装置的动模试验,对TA饱和时母线区内外故障、系统振荡时母线故障和母线故障时有流出电流进行模拟,可定量分析和检查保护的各种工况识别能力及保护的动态动作特性。
Dynamic test has more advantages than that of traditional one. Under certain circumstances, it can simulate correctly the expected system characteristics. Through dynamic simulation test of bus protection devices, the bus area internal and external fault with TA saturation, bus fault under power system oscillation and flux current due to bus fault can be simulated. Quantitative analysis, check-up of protection condition identification and protection dynamic performance characteristic can be made.
