VSC-HVDC, with voltage source converter technology, has strong controllability and is an ideal solution for wind farm grid connecting. This paper studies the control strategy of VSC-HVDC in wind farm grid connecting. By controlling the frequency of wind farm at wind farm side converter station, squirrel cage induction generator can be operated at variable speed, and therefore the utilization of wind energy is improved at low wind speeds. For double fed induction generator (DFIG) wind farm, the convertor station controls the frequency at rated value that has obtained also a very good effect.
