摘要
我国风能资源丰富,开发潜力巨大,尤其是在农业生产中已凸显其重要地位。通过对步进电机进行控制进而调节发电机叶片的偏向角,使叶片始终处于正面迎风的状态,从而保证风力发电机时刻输出最大功率。为此,以步进电机为传动机构,采用单片机C语言编程,以L298和L297等芯片构成步进电机驱动电路,制作出偏航控制系统的仿真模型。实测表明,系统具有功率输出最大、硬件结构简单、软件编程容易和价格低廉等特点。
In our country, the abundant wind power energy is a huge exploit potential market, especially in the ture production. On the basis of the deeply research into the working principle of the step motor, the regnlatio agriculn of the leaves biased angle had been controlled by using the single - chip C programming and the driver IC L298, L297 to control the step motor, so that the leaves are always been in the positive wind state and the maximum output power of wind generators had been ac yaw control system had step motor drive system easily and inexpensive. quired. By using the PORTEL software the Printed - Circuit - boards and schematic sheets of the been obtained. The experiment results show that the system which had been designed by using has the features such as the maximum power output , the simple hardware, software programming
