| 摘 要： | 提出了无刷励磁同步风力发电机励磁系统设计方案，采用可控硅静止励磁装置向交流励磁机定子励磁绕组提供直流电，励磁机发出交流电经过旋转整流器供给风力发电机励磁。只需跟随风速变化，控制励磁机的励磁从而可以控制同步发电机的励磁，使得输出电压恒定。在额定风速以下，获得最大风能利用系数，额定风速以上，保证输出功率恒定。并提出了基于单神经元自适应PID控制算法的控制器设计，该系统具有可靠性高、抗干扰能力强、硬件简单和系统可扩展性强的特点。

| Abstract: | This paper presents design scheme of wind brushless synchronous generator excitation system. SCR static excitation devices are used to AC exciter stator field winding to provide DC, AC from the exciter through a rotating rectifier supply wind turbine excitation. Simply follow the changes of wind speed, to control the main exciter, thereby control the excitation of synchronous generator, so that constant output voltage can obtained. Below the rated wind speed, the largest wind energy utilization factor can o... |
