Dual-rotor wind turbine with high-soft tower can break the limits of wind energy utilization of conventional single-wheel wind turbines and improve the efficiency of wind energy utilization in low wind speed areas. The natural frequency of the flexible tower is within the operating speed range of the wind turbine

so there is a speed exclusion zone. Based on the normal operation control of wind turbine

a resonance crossing control algorithm is proposed to prevent the resonance between the wind turbine impeller and the tower during operation.The algorithm finds the resonance interval through Campbell diagram

and adds speed control on the basis of optimal torque control to achieve fast resonance crossing. A large number of simulation tests were carried out on a simple wind turbine model developed on Simulink for steady-state wind and in three scenarios with different turbulence intensities. The simulation results show that the algorithm can achieve fast and effective resonance traversal under all the above conditions.
