Title:
WIND POWER GENERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/049502
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a wind power generation device that, when a plurality of control functions are executed simultaneously with pitch angle control, ensures stability by securely activating a control function that is to be given precedence and improves reliability. The present invention comprises: a blade that rotates by receiving air flow; a pitch angle control device that controls the pitch angle of the blade with a plurality of control functions; and an output adjustment means for the plurality of control functions of the pitch angle control device are provided. The pitch angle control device selects a control function, of the plurality of control functions, that has precedence on the basis of the state of the wind power generation device. The output adjustment means limits pitch angle output for at least one of the plurality of control functions other than the control function that has precedence.
