Abstract

Considering the influence of the tower vibration such as fore-aft/ side-to-side in the offshore wind turbine, the Passivity-based Control (PBC) method is proposed to suppress the tower vibration based on the offshore Permanent Magnet Synchronous Generator (PMSG). The PCH model of the tower is established and the energy compensation of the system is adopted to increase the damping of the tower. In comparison with PID controller, the PBC method not only suppresses the vibration of the tower effectively while reduce the fatigue load of tower, but also reduces the influence of maximum capture of wind energy and the drive-train torsional vibration, stabilizing the output power of the generator. The effectiveness and superiority of the PBC method proposed is verified by the theoretical analysis and the simulations by comparing with PID.
