Analysis on the Fault Trip of AC Filter Resistance Fundamental Over-current Protection in Suidong Converter Station
摘要
Abstract
During the test and operation of Suidong converter station in Yunnan-Guangdong DC transmission project, the fault tripping of resistance fundamental over-current protection is analyzed which resulted to the bipole block of UHVDC project. The reason of this accident is given according to the transient fault records (TFR) of protection equipment and the oscilloscope. The different results are acquired in the same algorithm with different TFR. Two methods are given to solve this problem and proved by RTDS test. When these methods are utilized in future China UHVDC control and protection system, the UHVDC can operate better.关键词
