Title:
WIND POWER GENERATOR
Document Type and Number:
Japanese Patent JP2017053307
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a wind power generator device capable of substantially improving a power generation efficiency under a low wind speed by accelerating and rotating a rotor.SOLUTION: Control means 4 repeats a control in such a way that when wind speed detecting means 17 detects a prescribed average wind speed, changing-over means 9 changes over a power regenerative type motor 3 to a motor mode and accelerates and rotates the rotor 2 until rotation speed detecting means 17 detects that a peripheral speed of the rotor 2 reaches a specified value, thereafter the motor 3 is changed over to the power generator mode by the changing-over means 9 to generate power and when the wind speed detecting means 17 detects again the prescribed average wind speed, the changing-over means 9 changes over again the motor 3 to the motor mode and the rotor 2 is accelerated and rotated.SELECTED DRAWING: Figure 1
