PURPOSE: A method for controlling the pitch of a blade of a wind power generator is provided to make a wind speed reach from a cut-in speed at which the generator can generate power to a synchronized speed of the generator. CONSTITUTION: A method for controlling the pitch of a blade of a wind power generator is as follows: a step of maintaining the pitch angle of the blade in a feathering state (S10); a step of controlling the pitch angle of the blade over an optimal pitch angle before the synchronization of the generator if a wind speed is over a cut-in speed at which the generator can generate power (S20); and a step of controlling the pitch angle of the blade to the optimal pitch angle after the synchronization of the generator if the wind speed is over a synchronized speed of the generator (S30). [Reference numerals] (S10, S50) Feathering a blade pitch angle; (S20) Controlling the blade pitch angle before the synchronization of a generator; (S30) Controlling the blade pitch angle after the synchronization of the generator; (S40) Controlling blade pitch angle at a rated speed |
