Study on the influence of lateral damping strategy of offshore wind power on tower vibration

Abstract:
Due to the complex operating conditions of offshore wind turbines, the tower is in vibration for a long time, which will not only reduce the output performance of the turbines, but also directly affect the operation accuracy and fatigue life of the relevant parts of the turbines. There are hidden safety hazards, and then affect the effective power generation and operation life of the turbines. This paper takes the offshore wind turbine as the research object and aims to mitigate tower vibration. A control system model based on lateral damping strategy is established. The simulation of offshore variable load conditions is carried out and simulated with GH software. The torque vibration of spindle rotating hub, tower vibration and power output of the wind turbine system are analyzed with the addition of lateral damping, and the correctness of the lateral damping strategy control system model and the effectiveness and advancement of lateral damping strategy to mitigate tower vibration are verified. To provide technical support for further improving the stability of offshore wind turbine operation and ensuring the safe and effective operation.
