Therefore, the ability for doubly fed induction generator (DFIG) variable speed wind turbine power converters to withstand abnormal conditions is strictly imperative in order to achieve its lifetime specifications and also fulfil the grid codes. During the fault by flowing the high current for a several micro seconds transient operations are very crucial for high power insulated-gate bipolar transistor modules. After clearance of an external short-circuit fault, grid-connected wind turbines should restore their normal operation without power loss caused by disconnections. The fast development of wind power generation brings new requirements for wind turbine integration into the network.
