摘要

研究了一种基于无刷直流(BLDC)发电机的分布式风能转换系统(WECS)。采用三相PWM整流器和最大功率点跟踪算法控制无刷直流发电机转速，使风力发电机输出功率达到最优。在直流母线上接一个PWM电压源逆变器，用于对用户负载的交流电源进行电压和频率调节。对基于无刷直流发电机的无刷直流系统进行了子系统建模，并在MATLAB/SIMULINK环境中对其在不同风速条件和用户负荷下的动态特性进行了仿真。

Modeling and simulation of a brushless DC permanent-magnet generator-based wind energy conversion system

This paper deals with a brushless DC (BLDC) generator-based wind energy conversion system (WECS) for distributed electric power generation. Three-phase PWM rectifier and maximum-power-point-tracking algorithm are used for controlling the BLDC generator speed to achieve optimum energy output from the wind turbine. A PWM voltage-source inverter is connected to the DC bus for voltage and frequency regulation of AC supply to consumer loads. The BLDC generator-based WECS is modeled by sub-systems, and its dynamic behavior is simulated in MATLAB/SIMULINK environment for different wind-speed conditions and consumer loads.
