Abstract: Power electronics converter as the connector of wind turbines and power network, provide wind generators motor control, and also output quality electricity. So the control strategies of electronic converters is very important. The control strategies of line side converter,generator side converter and low voltage ride through were analyzed. Finally,the future trend of converter control strategies was also given.
Key words: direct-driven wind generation system; line side converter control; generator side converter control; low voltage ride through control; control strategies
