Title:
WIND-POWER GENERATION DEVICE, CONTROL METHOD FOR WIND-POWER GENERATION DEVICE, WIND-POWER GENERATION SYSTEM, AND CONTROL METHOD FOR WIND-POWER GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2011/016278
Kind Code:
A1
Abstract:
Even when the frequency of an electric power system suddenly varies, the electric power system is stable. Disclosed is a wind-power generation device (1) comprised of a rotor (7) rotated by wind power, a power generator (5) driven by the rotation of the rotor (7), and a control device (20) by which, when the frequency of an electric power system (13) is equal to or less than a predetermined rated frequency, and the number of rotations of the power generator (5) is equal to or more than a first predetermined value, the generated power of the power generator (5) is increased while the number of rotations is decreased. Thus, even when the frequency of the electric power system (13) varies, the variation of the frequency can be suppressed, and the electric power system (13) can be stabilized.
