Abstract

Increases the operating rate of windmills by improving control in the event excessive loads are detected on the movable parts of the windmill. The windmill driving system (5) includes: a plurality of driving devices (10), each of which has a driving gear (24a), and the driving gear (24a) is arranged on the movable part of the windmill (101) One of the structures, and meshes with the ring gear (107) of the other structure provided in the movable part of the windmill; the state quantity detection part (80), which is used for each driving device on a plurality of The load generated between the driving gear and the ring gear of the driving device is monitored; and the control part (110), in the case that the state quantity detection part (80) detects that the load is abnormal, the control part (110) makes the load Reduced control.

Description

technical field [0001] The present invention relates to a windmill drive system used for a movable part of a windmill and a windmill. Background technique [0002] For example, as disclosed in JP2015-140777A, as a windmill used as a wind power generation device, the following windmill is known. machine, etc.; and blades (wings) that are provided rotatably with respect to a rotor (hub, main shaft portion) provided in the nacelle. This wind turbine has a yaw drive device, a pitch drive device, or the like as a drive device that rotates one structure body relative to the other structure body among the movable parts of the wind turbine. The yaw driving device rotates the nacelle as one structure relative to the tower as the other structure according to the wind direction. The pitch drive device adjusts the pitch angle of the blade by rotating the shaft portion of the blade as one structure with respect to the rotor on the nacelle side as the other structure. In many cases, mu...
