Abstract: A hydraulic transmission for a wind turbine that includes a rotor, one or more blades mounted to the rotor, a hydraulic pump mechanically connected to the rotor, and a hydraulic motor. The hydraulic pump and the hydraulic motor are connected to one another by a high pressure circuit. The hydraulic pump maybe a variable displacement hydraulic pump and the hydraulic motor may include a variable displacement hydraulic motor. The wind turbine, including the rotor, the blades of the rotor, the hydraulic pump, and the hydraulic motor may be controlled according to different approaches.
