Abstract

This paper deals with the voltage and frequency control of the generated electricity from a permanent magnet wind-turbine. The wind turbine is directly connected to a permanent magnet synchronous generator in order to avoid the losses associated to the gearbox so that only an AC/DC/AC power converter is used to control the variable voltage and frequency. The AC/DC converter is a three phases diode bridge rectifier, the DC/DC converter consists of a Boost converter which keeps the voltage level nearly constant over the whole wind speeds to supply satisfactory a single-phase DC/AC inverter which has four insulated gate bipolar transistors since a single-phase output with constant voltage and frequency is desired.The simulation of the whole system including the permanent magnet synchronous generator and it is verified that the design of the AC/DC/AC power converter and its control strategy work very well and can be readily used in RL loads in rural areas.

农村发电用永磁风力发电机AC/DC - DC/DC - DC/AC变换器控制系统设计与仿真

本文研究了永磁风力发电机组的电压和频率控制问题。风力涡轮机直接连接到永磁同步发电机，以避免与齿轮箱相关的损耗，因此仅使用AC/DC/AC电源转换器来控制可变电压和频率。AC/DC转换器是一个三相二极管桥式整流器，DC/DC转换器由一个Boost转换器组成，该转换器在整个风速范围内保持电压水平几乎恒定，以提供令人满意的单相DC/AC逆变器，该逆变器具有四个绝缘栅双极晶体管，因为需要具有恒定电压和频率的单相输出。通过对包括永磁同步发电机在内的整个系统的仿真，验证了所设计的AC/DC/AC功率变换器及其控制策略的有效性，可以很好地应用于农村地区的RL负载。
