摘要
为了获得最大的风能,提高风力发电机的发电效率,对风力机偏航控制系统进行了研究。该系统采用主动迎风的方式,通过风向传感器测得机舱的相对风向,由DSP计算出偏航角度,采用细分控制技术控制偏航步进电机正转或反转,从而实现偏航控制系统自动跟踪风向。实验表明,采用DSP控制,实时性较好,细分技术控制的步进电机,运行精度较高,系统能快速、准确使机舱对风。
In order to capture the maximum wind energy and improve the efficiency of wind turbine, the yaw control system was researched. This system takes the initiative to windward. The relative wind direction is measured by the wind sensor. According to the relative wind direction, yaw angle is calculated by the DSP and generate the drive pulse. Then the stepping motor is controlled to turn or turn over by the subdivision control technology to make the turbine windward. Through this way, the yaw control system can track the wind direction automatically. Experimental results show that using DSP control, the real-time performance of yaw system is good and operation precision of stepping motor is high by the subdivision control technology. Therefore, the yaw system tracks the wind direction quickly and exactly.
