Title:
WIND TURBINE GENERATOR
Document Type and Number:
WIPO Patent Application WO/2016/152640
Kind Code:
A1
Abstract:
Provided is a wind turbine generator, wherein the rated rotational speed of a wind turbine is maintained by an electric motor, and fluctuations in torque caused by lift of the lift-type blade due to rotation are made uniform by regulating fluctuations in the amount of current withdrawn, enabling a stable voltage to be achieved. This wind turbine generator comprises a main shaft (4), a motor (7) which rotates this, and a controller (9) that detects fluctuations in load of the motor (7) and automatically adjusts the amount of electric current withdrawn, wherein the main shaft (4) is rotated at a rated engine speed by the motor (7), thereby maintaining a rated voltage, and fluctuations in torque generated in the main shaft (4) due to the lift generated in the lift-type blade (6) of the wind turbine are made uniform by automatically adjusting the amount of current withdrawn, enabling a stable voltage to be output.
