Title:
風力発電装置及び出力制御方法
Document Type and Number:
Japanese Patent JP5244923
Kind Code:
B2
Abstract:
A wind turbine generator (10) derives the gradient of a change in output power of a generator (20) that generates power by rotation of a wind turbine rotor (16), and determines an increase/decrease in the output power of the generator (20) on the basis of the derived gradient of the change in output power. Then, when the frequency of a utility grid (42) has dropped, power control is performed on the basis of the determination results. Therefore, a decrease in the amount of power supplied to the utility grid (42) can be more effectively compensated for by accurately detecting output power fluctuations of the generator (20), using a simple configuration.
