The patent relates to improvements in wind turbines and in particular to a system for optimising the energy converted from a wind turbine situated in a gusty environment.
A wind turbine system comprises a wind turbine 1, a regenerative drive system 2, a wind-speed sensor 4 for measuring local wind speed, and a controller 3. The wind turbine 1 comprising a motor-generator system 6 which is operatively connected to the regenerative-drive system 2, the motor-generator system 6 being drivable as a motor by the regenerative drive system 2 to increase a rotational speed of the wind turbine 1, and being operable as a generator by the regenerative drive system 2 to decrease a rotational speed of the wind turbine 1. The controller 3 is operatively connected to the wind-speed sensor 4 and the regenerative drive system 2, and is operable to control operation of the regenerative-drive system 2 to thereby control the rotational speed of the wind turbine 1 in response to signals received from the wind sensor 4 indicative of gusting changes in the local wind speed.
