基于不同集成方案的浮式风-浪联合发电系统动力响应研究OA

To achieve cost-effective development of offshore wind and wave energy,this study in-tegrates the oscillating buoy wave energy converter(WEC)into the Haiyou Guanlan floating offshore wind turbine(FOWT).This integration aims to enhance power generation efficiency while reducing the motion response of the FOWT.Based on the potential flow theory and Morison formulation,the hydro-dynamic coupling analysis of the floating foundation and WEC is realized in AQWA,and the aerodynam-ic influence of blades is simulated in detail in FAST by using blade element momentum theory to realize the full coupling analysis.The accuracy of the numerical model was validated using data from physical model tests.Four WEC integration schemes were evaluated for their effects on the motion response and power generation efficiency of the FOWT.Results indicate that integrating a six-buoy WEC array be-tween the central and side columns of the semi-submersible foundation effectively suppresses the pitch motion of the wind turbine.Under extreme conditions,the maximum value and standard deviation of the pitch motion were reduced by 16.2％and 10.3％,respectively.Compared to the single FOWT,the hybrid power generation system achieved a 13.9％increase in power generation efficiency.The findings demonstrate that WEC integration significantly enhances power generation efficiency and reduces the motion response of the FOWT.
