    Abstract: A closed loop turbine speed control system for a turbine power production system including a closed loop hydrostatic transmission system for the transfer of energy from a wind turbine rotor to a generator. A displacement actuator is arranged for receiving a displacement control signal from the control system and for controlling a displacement of the displacement motor. The control system includes a turbine rotor speed feedback control loop for calculating the displacement control signal based on deviations of a turbine rotor actual rotational speed from a turbine rotor set rotational speed. In addition a hydraulic pressure meter measures the hydraulic pressure of the hydrostatic system and provides a hydraulic pressure signal as an input to a pressure feedback control loop for stabilizing the displacement control signal based on the hydraulic pressure signal.
