摘要

海上浮式风机在海洋环境中会受到多种因素的影响，这些海洋环境会显著改变浮式风机的运动状态，进而使风机的发电性能发生改变。研究了不同风浪条件下海流对半潜型浮式风力发电机运动响应的影响，并比较分析了海流对风力机发电功率的影响。选取半潜型浮式平台和5 MW风力机作为研究对象，采用OpenFAST、FAST to AQWA(F2A)和AQWA软件进行仿真。首先，在稳态风规则波、稳态风不规则波和湍流风不规则波3种环境条件下，分别计算了浮式平台的纵荡、垂荡、纵摇运动响应以及发电功率；然后，计算添加海流因素之后上述海况下的运动响应和发电功率。结果表明：海流主要对纵荡运动产生较大影响，最大差异达到13%，但对垂荡运动和纵摇运动的影响相对较小；在3种环境条件下的发电功率计算中，海流对风力发电机的平均发电功率和最大发电功率没有影响，工况间的差异小于1%，但在较复杂的工况下，发电功率的标准偏差差异较小，海流不会对发电功率的变化震荡程度产生影响。

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.
