Abstract
Aiming at the frequent AC filter protection trip in Yun-Guang HVDC transmission system, the root cause of inconsistent protection operation is analyzed according to the hardware configuration of protection device.Based on analyzing the data of transient fault recorder, it is found that there is difference between delay time and protection device operation time in the aspect of delay-setting.Improvement measure on time delay is proposed and simulation experiment and on-spot fault recorder playback experiment are made on RTDS.The simulation results show that the improved protection can avoid the mai-operation caused by impact current effectively.关键词
