| 摘 要： | 通过研究永磁同步发电机转速与DC-DC转换器中占空比的关系,提出一种基于调整DC-DC转换器的占空比实现最大功率点跟踪的方法。针对在最大功率点附近由于占空比不稳定导致输出功率振荡的现象,采用一种在最大功率点附近变占空比步长的方法,并在Matlab/Simulink下进行建模仿真,验证此方法能使风力发电机快速达到最大功率点。

| Abstract: | By studying the relationship between the perma- nent magnet synchronous generator speed and duty cycle of DC-DC converter, a tracking method is proposed to achieve maximum power point based on controlling the duty cycle of DC-DC converter. In view of the phenomenon of output power oscillation caused by duty cycle instability near the maximum power point, a method of changing step size of duty cycle is used. A model in Matlab / Simulinkthen is simulated to verify that this method may allow the wind generator to reach the maximum power point quickly. |
