摘要

本文研究了一种最大功率点风能电池充电系统的动力学特性和直流变换器的实现。讨论了5千瓦以下风力发电机所需的设计规范以及风能系统不同组件的建模。通过实现一个功能发电机，实现了不同风速下最大功率点跟踪的DC - DC变换器的占空比控制。功能发电机根据发电机转速调节变流器的占空比。为了研究占空比控制方法和系统的稳定性，利用MATLAB Simulink对系统进行仿真，确定系统的响应。结果表明，所提出的占空比控制方法在最大功率点跟踪中是有效的。同时，系统对高频干扰的响应是稳定的。

Dynamics of Maximum Power Point Wind Energy Battery Charging Systems

In this paper the dynamics of a maximum power point wind energy battery charging system and the implementation of a DC to DC converter is investigated. The required design specifications for a sub 5 kW wind generator are discussed as well as the modelling of the different components of the wind energy system. The duty cycle control of the DC to DC converter for maximum power point tracking at different wind speeds is done by implementing a functional generator. The functional generator adjusts the duty cycle of the converter according to the generator speed. In order to investigate the duty cycle control method and the system’s stability the system is simulated with MATLAB Simulink to determine the response. It was found that the proposed duty cycle control method is effective in maximum power point tracking. Also, that the system’s response is stable for higher frequency disturbances.
