摘要
直驱风力发电系统使用不控整流电路实现交直变换,在风速较低时发电机输出电压很低,需要在整流电路后加上Boost升压斩波电路实现升压,以保证后接逆变电路正常工作。阐述了直驱风力发电系统构成,详细分析了直/直升压变换电路的原理与设计方法,给出了升压斩波电路各元件的参数选择,并对2.2 kW实验系统完成了设计、制作。运行结果表明,变换电路能够实现直/直升压变换,系统效率较高,具有很好的实际应用价值。
The uncontrolled rectifier was used in direct driven wind power system to convert AC into DC. The output voltage of generator was small when wind speed was low, and the Boost convertor was needed to promote DC voltage, so as to ensure inverter work normally. The constitution of the wind power system was expatiated, the principle and design method of DC/DC boost convertor were analyzed in detail, and the element parameters of the convertor were chose. The 2.2 kW testing equipment was worked out, and the result of operation show that, the convertor can carry out promoting voltage, its efficiency is high, and it has good usefulness.
