"Wind Turbine Generator And Tidal Current Generator And Operation Method Thereof"
Abstract: 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 ef-ficiency, 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.
