Abstract
In order to study the effect of high voltage ride through (HVRT) of doubly-fed wind power system under sator winding inter-turn short circuit (SWITSC) faulty condition,based on the multi loop theory,a simulation mode of doubly fed induction generator under SWITSC faulty condition was established,the S-function in the MATLAB/Simulink was established.On the basis of fault loop characteristics,mathematical model of DFIG wind turbine on ABC coordinate system and dq0 coordinate system were established under normal and fault condition,and the electromagnetic characteristics was analyzed briefly under SWITSC fault,then the capability of high voltage ride through of DFIG was analyzed,the reason and the transient process of wind farm voltage rise were analyzed.The standard of high voltage ride through was provided.Focused on the simulation results of HVRT of DFIG under SWTTSC faulty condition,the explanation was given.The results showed that SWITSC faulty destroyed capability of HVRT of DFIG to a great extent.关键词
