Analysis of Abnormal Resistance Data of Resistors in a VSC-HVDC Converter Station
This paper reports an analysis on the continuous detection of abnormal resistors during the annual maintenance period of a flexible DC converter station.Through on-site disassembly,it was found that there were hidden dangers in the equipment structure.Measures for optimizing and rectifying resistor edge structure and installation process were proposed.After two years of tracking and testing comparison,the results have showed that the optimization measures are feasible and effective,effectively ensuring safety of equipment operation and providing reference for coping with similar problems.
