摘要
Abstract
Grounding fault is a common fault in new energy power plants.Zero sequence current protection can effectively cut off faults,and zero sequence current is collected through a zero sequence current transformer.If the wiring of the zero sequence current transformer is incorrect,it will cause a deviation in the collection of zero sequence current and affect the protection action.Through grounding protection tripping,this article analyzes the impact of zero sequence current transformer wiring on protection action,providing experience for the installation,commissioning,and protection fault analysis of zero sequence current transformers in new energy power plants.关键词
