| 摘要 |
A wind turbine power production system (1) with a closed loop hydrostatic transmission system (10) for the transfer of mechanical energy from a wind turbine rotor (2) to an electric generator (20) where the hydrostatic transmission system (10) comprises a closed loop with a pump (11) and a motor (12) connected by tubes or pipes (13, 14). The assembly of the hydrostatic transmission system (10) and the turbine rotor (2) is arranged to rotate about a vertical axis (8), and the rotating motor (12) is arranged on or near the ground in the tower (4).
