Embodiment Construction

[0028] An embodiment of the wind power generator and the yaw rotation driving method of the wind power generator according to the present invention will be described below with reference to the accompanying drawings.

[0029] figure 1 It is a block diagram showing a schematic configuration of the wind power generator of this embodiment.

[0030] like figure 1 As shown, the wind power generation device 1 has: a windmill tower 2, a nacelle 3 arranged on the upper end of the windmill tower 2, and a rotor hub 4 arranged on the nacelle 3 and capable of rotating around a substantially horizontal axis. A plurality of windmill blades 5 are installed radially around the rotor hub 4 around its axis of rotation. As a result, the force of the wind blowing to the wind turbine blade 5 from the direction of the rotation axis of the rotor hub 4 is converted into power to rotate the rotor hub 4 around the rotation axis. This embodiment describes the case where three wind turbine blades 5 ar...

Abstract

A yaw drive device is completely or partially eliminated and electric power consumption in a nacelle is reduced. Moment with respect to the axis of an impeller tower is calculated, and an angle command value with respect to the axis of the impeller tower is calculated by adding a yaw control command value to a reference command value for canceling the calculated moment. Then, a pitch angle command value for each impeller blade is set based on the angle command value with respect to the axis of the impeller tower.

Description

technical field [0001] The invention relates to a wind power generating device and a yaw turning driving method of the wind power generating device. Background technique [0002] The wind power generation device is provided with a windmill generating unit capable of swinging and turning on the upper end of the windmill tower, and the windmill generating unit has a windmill and a generator driven by the windmill to rotate. The wind power generation device pivots the wind turbine generating unit relative to the wind turbine tower according to the direction of the wind (rotation on a substantially horizontal plane) so that the wind turbine receives wind force from the front. [0003] In the above-mentioned wind power generation device, the ring gear is fixedly arranged on the tower side, and the pinion gear meshing with the ring gear is arranged on the side of the wind turbine generating unit, and the yaw of the wind turbine generating unit is performed by driving the pinion to...
