Doubly-fed induction generators (DFIGs) have been widely used in wind generation because of their less loss and simple control strategy. There are many ways to reduce the current and voltage fluctuation in fault duration in DFIG and crowbar circuit is a widely used method. However, the crowbar circuit cannot limit the current and voltage after fault very effectively. This paper analyses the model...
Nowadays, wind power has been developed very fast in China and the installed capacity of wind turbine has been increased rapidly. As an important wind driven generator, doubly-fed induction generator (DFIG) has been applied very popularly for its many advantages, such as less converter losses and simpler control methods. When the grid voltage dip occurs, a crowbar beside the rotor-side converter is...
