摘　　要：为有效进行偏航迎风控制,提高对风精度,提出了一种新型的偏航系统控制算法——VANE-HILL CLIMB- ING,该算法的核心内容是在大范围风向变化时采用风向标控制算法,而在小范围风向变化时则采用功率控制算法。采用PSCAD仿真软件建立了双馈电机的仿真模型,给出了程序流程框图,进行了仿真实验。通过仿真,得到仿真曲线,并进行了分析,结果表明该算法有效可行,提高了对风精度,增加了系统的输出功率。In order to carry out yawing control effectively, a new algorithm for yawing control system-VANE-HILL CLIMBING control algorithm was proposed, which adopts Vane control algorithm in large change scale of wind and Hill Climbing algorithm in small changing scale of wind. Modeled doubly-fed wind turbine generator simulation model was set up with PSCAD, also the flow chart, and simulation with PSCAD were carried out. The simulation curves was educed and analyzed. The result show that the new algorithm is valid, which can enhance the accuracy of yawing and the output power of system.
