Darrieus wind turbine electric generating system
A wind electric system intended to provide power to a power grid, for use with a wind turbine which has no starting torque. The generator is one which can function as a motor as well. When the wind is too light to permit generation, an overriding clutch mechanically disconnects the generator shaft from the turbine shaft. The clutch has also the capability of locking the generator shaft to the turbine shaft in response to a control signal. When wind speed is great enough to permit generation and the turbine is stopped, a control signal is issued locking the generator shaft to the turbine shaft. Power from the power grid causes the generator to function as a motor and accelerate the turbine to permit it to be rotated by the wind. The clutch is then returned to overriding operation and electrical generation continues until wind speed again becomes too light.
