| 摘 要： | 为了提高风能利用率、风力发电能量转换效率,提出一种新型的外转子永磁风力发电机.建立了永磁发电机的数学模型,针对双PWM变频器的特点提出了控制策略对变流器进行控制,通过变流器交-直-交的变换,将发电机发出的变频变幅值交流电转化为可用的恒定频率的交流电,并通过对变流器的控制实现了最大风能俘获的功能.

| Abstract: | Exterior rotor generator improves the efficiencies of wind and wind-energy conversion. Its mathematical model is built in this paper. Based on the characteristics of the double PWM frequency changer, we propose a control strategy for controlling the converter. By means of the AC-DC-AC converter, we convert the generator output with varying-frequency and varying-amplitude into a constant-frequency AC for applications. The optimal usage of wind power is also realized. |
