超高压电网故障电流限制器在RTDS上的仿真试验研究

RTDS-based Simulation Test Study of Fault Current Limiter on EHV Grid

建立了串联谐振型故障电流限制器实时仿真平台,对瓶窑500 kV变电站故障电流限制器(FCL)进行了不同运行工况下的RTDS实时仿真试验,FCL保护控制策略及限流性能进行了试验分析。根据仿真试验,得出合理有效的结论,同时也验证了FCL实时仿真模型的合理性。

RTDS-based simulation tests have been made for 500 kV fault current limiter in Pingyao Substation under various operating conditions on the established real-time simulation platform for series resonant type FCL.This paper presents the test analysis of the protection control strategies and current limitation properties,and the simulation tests verify both the validity of the results and the rationality of the real-time simulation model for FCL.
