铰接式基础风力机多目标优化及动力响应研究
Multiobjective optimization and dynamic response of an offshore wind turbine with an articulated foundation
摘要
Abstract
Aiming at the foundation design and optimization of a new type of wind turbine with an articulated foundation,a high-dimension mathematical model with three-objective optimization is established by comprehensively considering the operational safety and stability,economic cost,and motion performance of an articulated offshore wind turbine.The model adopts a type of nondominated sorting multiobjective genetic algorithm(NSGA-Ⅲ)based on the reference points to optimize the foundation dimension of the wind turbine and uses the fuzzy optimization method to perform fuzzy evalua-tion on the obtained Pareto solution,thereby obtaining the optimal scheme satisfying different evaluation indices.Based on this,the aerodynamic,hydrodynamic,and structural coupling analysis method was adopted to construct the motion control equation in the time domain for the analysis of the dynamic response.The calculation results showed that under the rated wind speed and oceanic conditions,the designed wind turbine with an articulated foundation meets the require-ment of safe power generation.Meanwhile,compared with the initial design scheme,the articulated foundation structure based on the multiobjective optimization algorithm and fuzzy evaluation displays superior motion and load performance and is more economical.The related algorithm and optimization process also provide a new idea and reference for subse-quent optimization design work with different foundational forms.关键词
