Stator Grounding Fault Location Method of CRDM Power System Generator in Nuclear Power Plant Considering Spatial Distribution Characteristics of Windings
摘要
Abstract
Generator stator ground faults are the most common faults in the control rod drive system of a nuclear power plant.Accurately solving the winding fault location is of great significance for rapid fault maintenance and power supply recovery.Based on the spatial structure characteristics of the generator stator winding of the rod-controlled power supply system,the geometric modeling of the winding potential distribution characteristics under the Zig-Zag winding connection mode is carried out.Based on the spatial distribution characteristics of winding potential,the winding fault location method is constructed to realize the precise positioning of the whole winding.PSCAD/EMTDC simulation analysis and dynamic simulation test verify the accuracy of the proposed method,and prove that it is not affected by the grounding fault location,transition resistance and generator operation status.关键词
