Abstract

To adapt to the complex and changeable offshore environment, optimize the tower structure of the floating wind turbine unit to efficiently utilize wind resources and reduce steel costs. Taking a ship-mounted wind turbine as the research object, the dynamic response of the floating platform is introduced as an important constraint condition that affects the bending deformation of the tower. The numerical optimization model of the floating platform wind turbine tower is established to achieve the goal of optimizing minimum weight, with tower construction requirements and regulations as basic constraint conditions, and the genetic algorithm is used to optimize the model. The optimization results show that the optimized results reduce the mass of the tower by 35 % and increase the stiffness by 25% under the premise of ensuring stable power output.
