Development and Verification of Control Strategy to Avoid Soft Tower Resonance for Wind Turbine

Soft tower can significantly improve annual energy production (can be increased by 5%~20%) for low wind speed wind farm with high wind shear. It is of great significance to reducing the cost of energy. However, because of the intersection of tower first-order natural frequency with rotor speed 1P, t...

description Soft tower can significantly improve annual energy production (can be increased by 5%~20%) for low wind speed wind farm with high wind shear. It is of great significance to reducing the cost of energy. However, because of the intersection of tower first-order natural frequency with rotor speed 1P, there is a risk of resonance. Therefore, a soft tower control algorithm named speed exclusion zone controller is designed relying on the H125 high tower of 2MW D121 type wind turbine, which can realize speed crossing through adaptive control. The strategy can avoid long-term operation of wind turbine in the speed exclusion zone, and reduce abnormal load due to resonance. The feasibility of this control strategy at the design stage was tested by Bladed software and verified on the prototype. The results show that the speed exclusion zone control strategy of soft tower can effectively solve the 1P resonance problem of soft tower wind turbine.
