Abstract: PURPOSE: A method of controlling wind power generator is provided to recover the frequency quickly when the electric power network falls into a problem such as the generator breaks down or load increases and to supply more electricity to the power network. CONSTITUTION: An inertial control method for wind power generator has four different steps for controlling the generator. The first step includes acquiring the frequency information calculated by using the voltage of the generator or the voltage which has been received from the power network of the generator. The next step is to receive the velocity information of the rotator of the generator, and the third step is to calculate the kinetic energy of the generator by utilizing the velocity information of the rotator. Last two steps include calculating individual droop coefficients of the generator and controlling the generator by using the calculated droop coefficients.
