Title:
CONTROL UNIT FOR WIND POWER GENERATION DEVICE, WIND POWER GENERATION DEVICE, CONTROL METHOD AND CONTROL PROGRAM FOR WIND POWER GENERATION DEVICE, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/177232
Kind Code:
A1
Abstract:
A control unit for controlling the power generation output of a wind power generation device provided with a windmill and a generator for generating power by means of the rotation of a rotor of the windmill. The control unit is configured to carry out a temporary power generation output increase process, which has a rated output mode for controlling the power generation output of the generator so as to approach a rated value, and has a first control for, when the rotor rotational speed of the windmill assumes a prescribed rotor rotational speed reduced state in the rated output mode, reducing the torque applied to the generator and suppressing a reduction in the rotor rotational speed, and a second control for subsequently increasing the torque and temporarily increasing the power generation output in a state in which a reduction in the rotor rotational speed has been suppressed.
