Abstract

The magnetic levitation technique is introduced into the wind yaw system to reduce the yaw power. Permanent magnet in the nacelle and stator winding in tower are designed to suspend the nacelle. And the wind yaw structure including the disc motor rotor and variable speed gear is proposed to drive suspension nacelle for wind direction. Based on the nacelle suspension mechanism, the disc rotor excitation current model is constructed, and then the nacelle yaw load torque model is given with the consideration of the wind and the nacelle suspension state, and then the whole dynamic model of the yaw disc motor is finished. In view of nonlinear and the high disturbance, the sliding mode speed controller is designed with the load torque observer to acquire the current reference, and then two PI current controllers are designed to realize wind yawing for wind direction. Based on simulation platform, the wind suspension yaw structure and the control strategy are verified with the stable nacelle suspension air gap and the yaw speed under the variation of load torque
