摘　　要：基于粒子群算法编写风力机叶片优化程序,利用Matlab/Simulink接口嵌入到FAST主程序之中实现叶片优化程序与FAST之间的交互,以实现风力机最大发电功率为优化目标,完成风力机叶片气动外形的自动寻优。该方法可考虑实际海况及风力机搭载平台对叶片优化结果的影响,可同时考虑风向分布对优化结果的影响。NREL 5 MW风力机低风速下的优化结果表明,经过优化后的风力机功率提高1.5%。当考虑实际风力机布置海域风向分布情况时,加权优化结果表明风力机最大功率可提高3.8%。Optimization program of the wind turbine blade has been developed based on the PSO algorithm in this manuscript. The program is embedded into the main program of the FAST by using the MATLAB Simulation interface to realize the interaction between the blade optimization program and FAST. The simulation goal aims at realizing the maximum power output and completing the automatic aerodynamic shape optimization of the wind turbine blade. The simulation method not only takes the influence of the actual sea condition and the deployment of the platform on the optimization result into consideration,but also considers the influence of the wind direction distribution. The optimization results at low wind condition showed that the power output of the optimized wind turbine has increased 1.5%. The weighted optimization result showed that the power output has increased 3.8% when the wind direction distribution is considered.
