The energy transmission system has a variable flow volumetric pump (10) driven by the output shaft (8) of a wind turbine (2). Two conduits (20A, 20B) connect the hydraulic pump to a hydraulic motor (30) which drives an electric alternator (32). The hydraulic pump has axial pistons driven by a variable inclination plate. The transmission is controlled by a closed loop servo system which has a speed detector (33) measuring the rotational speed of the alternator, and a regulator (40) receiving the output from this detector and using it to control the angle of inclination of the plate in the variable flow pump. |
