摘　　要：在RTDS中建立小电流接地系统模型,设置各种故障条件,通过放大器模拟实际电压、电流信号接入选线装置,进行动态仿真试验。比对RTDS试验和选线装置现场试验数据和选线结果,优化设计RTDS模型和选线系统,证明了所建模型正确性。A system model of NUGS in RTDS was established and various fault conditions were set. The de- vice was connected with RTDS through the amplifier to simulate the real signal and do dynamic simulation experi- ments. Comparing among device experiment results from RTDS simulation and field experiment, the RTDS model and line selection was optimized. It proves that the model is correct.
