海流对半潜型浮式风力发电机运动响应及发电功率的影响
Effects of ocean current on motion response and power output of semi-submersible floating offshore wind turbines
摘要
Abstract
Floating offshore wind turbines(FOWTs)are affected by various factors in the marine environment,which can significantly alter their motion states and thereby affect their power generation performance.The influences of ocean currents on motion response of the FOWTs under different wind and wave conditions are investigated,and their impacts on power output are also studied.A semi-submersible floating platform equipped with a 5 MW wind turbine is selected as the research object,and simulations are conducted using OpenFAST,FAST to AQWA(F2A),and AQWA software.The surge,heave,and pitch motion responses of the floating platform,as well as the power generation output,are calculated under three environmental conditions:steady wind with regular waves,steady wind with irregular waves,and turbulent wind with irregular waves.The motion responses and power generation output are then recalculated after the incorporation of ocean currents.The results indicate that ocean currents primarily have a significant impact on surge motion,with a maximum difference of up to 13%,while their effects on heave and pitch motions are relatively minor.In the calculation of power output under the three environmental conditions,ocean currents show no influence on the average or maximum power generation output of the wind turbine,with differences of less than 1%between cases.Additionally,under more complex conditions,the standard deviation of power generation output exhibits minimal variation,suggesting that ocean currents do not affect the fluctuation intensity of power output.关键词
