摘要(Abstract)：

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。
