| 摘 要： | 为实现较大风速变化范围内的功率控制,提出了将Buck变换器应用于小型风力发电系统的结构。采用几何参数法(K-G法)设计了Buck变换器的电感,并基于PWM开关模型建立了Buck变换器的小信号交流模型。在Matlab环境下分别建立了Buck变换器的电路仿真模型和传递函数的仿真模型,并利用该模型构建了以蓄电池和电阻为负载的风力发电系统模型。对Buck变换器的实验研究和对蓄电池充电的仿真研究结果表明,Buck变换器能满足风力发电系统功率控制的要求。

| Abstract: | To realize power control within the wide wind speed range,the paper presents a circuit structure of small wind-power generation systems with application of Buck converter.The inductor is designed by the geometric parameters method(K-G method),and a small-signal alternate model is built based on the model of the PWM switch.The circuit simulation model and transfer function model of Buck converter are developed under MATLAB environment,accordingly,the model of the small wind-power generation systems is built with using secondary battery and resistance as load.The control of constant voltage charging and floating charging and experimental study are carried out.The simulation and experiment results show that Buck converter can satisfy the requirement of power control. |
