This paper deals with two types of control method concerning induction generator used in wind power generating station. One is aiming at keeping the voltage magnitude of the node of the station and the other is aiming at keeping the constant power factor through the branch connecting to the station. Both of them are able to be in controllable area by adjusting generator reactive power using compensating capacitor. At first, the theoretical equations expressing terminal voltage and power factor for induction generator are derived, and then the compensating capacitor corresponding to the wind velocity variation is determined quantitatively. By using the proposed control method, it is confirmed to be able to keep the terminal voltage and operating power factor of wind power generation system to a target value even in the case when the abrupt deviation is caused by wind power disturbance.
