Study on on-site test method for DC protection equipment of HVDC
摘要
Abstract
The on-site regular test of DC protection equipment of HVDC after putting into operation has not been implemented due to lack of convenient and feasible test method and device,which will cause serious problem for security and stability of the power grid.This paper proposed a novel on-site test method of DC protection equipment of HVDC.The advantages of the method are follows as those no need to remove the equipment,explain and analyze the photoelectric conversion agreement,which eliminate the bad influence to the grid,and it has small security risk,and lower cost.The on-site test device for DC protection equipment of HVDC has been developed with adding quantity of optical current transformer and zero flux current transformers.Its validity was verified by on-site testing of DC protection equipment in Echeng convert station of Jiangling-Echeng ± 500 kV HVDC transmission project which is in operation for more than ten years.关键词
