采用爬山控制算法控制風力機偏航機構，與常規的偏航控制系統必須依賴風速風向傳
感器不同的是，該方法不需要風速風向傳感器裝置，只要測量風力發電機的輸出電壓和電流，根據風力機輸出功率的變化，不斷尋找最大功率點，由DSP 控制器發出指令調節偏航電機的起停和轉向，通過減速傳動裝置，從而快速有效的控制機艙始終處于迎風狀態。文中給出了1.5MW 雙饋風力機偏航控制系統的軟硬件設計，用PSCAD 軟件進行了仿真。采用DSP 控制器，實時性好，數據處理速度快，采用大的傳動比，使得機艙具有對風快速、平穩特點。

Abstract:Applying Hill-Climbing control algorithm to a yaw setup for wind turbine,it is
independent of any anemoscope and wind direction measure device compareing to general yaw control system.Only through measuring the voltage and current of the turbine output and
according to the changes of the turbine output power , the on-off and rotating derection of the yaw motor can be adjusted by controller, accordingly the turbine cabin will be always on windward status through gearing-down.The paper presents the software and hardware design of yaw control system for 1.5MW DFIG,and simulates the theory analyse by dint of PSCAD software. It also has a good real-time and fast data processing performance with DSP controller，and because of designing larger drive ratio of gearing,cabin of the system has a faster and balanced windward characteristic.
