WIND TURBINE GENERATOR AND TIDAL CURRENT GENERATOR AND OPERATION METHOD THEREOF |
摘要 |
An object of the invention is to provide a wind turbine generator or a tidal current generator which is equipped with a hydraulic transmission and achieves a superior power generation efficiency, and a operation method thereof. The wind turbine generator 1 comprises a hydraulic pump 12 of a variable displacement type which is rotated by the main shaft 8, a hydraulic motor 14 of a variable displacement type which is connected to the generator 20, and a high pressure oil line 16 and a low pressure oil line 18 which are arranged between the hydraulic pump 12 and the hydraulic motor 14. The pump controller 32 obtains a target torque of the hydraulic pump 12 at which a power coefficient becomes maximum, and then sets a displacement Dp of the hydraulic pump 12 based on the target torque and the pressure in the high pressure oil line 16. The motor controller 34 sets a displacement Dm of the hydraulic pump 14 based on a discharge amount Qp of the hydraulic pump obtained from the displacement Dp of the hydraulic pump 12 so that the rotation seed of the generator 20 becomes constant. |
