Abstract :
An active yaw control scheme for a horizontal axis wind turbine is proposed. The control strategy is based on measurement of the generated output power, without any wind intensity and/or wind direction sensors. Special attention is given to some control parameters to make the yaw driver less sensitive to wind turbulence. Results obtained in the laboratory implementation are presented and discussed in this paper
