| 摘 要： | 研究了一种小型离网型风力发电系统,系统采用三相不可控整流方式进行整流,使用Lc滤波电路对输出直流纹波进行滤波,采用Boost电路作为斩波稳压电路,利用PID控制反馈使输出电压稳定在600V左右。系统逆变部分采用三相五电平SPWM逆变器,可以使输出电压谐波减少,提高输出电能质量。最后对系统进行了仿真,仿真结果验证了此方法的有效性。

| Abstract: | This paper briefly introduces a small off-grid power generation system. Using three-phase uncontrolled rectifier is used and LC filter is carried out to reduce the dc output ripple, the boost circuit is adopted as Chopper voltage regulation circuit, the output voltage is stability kept on the vicinity of 600V with the usage of PID control, Three-phase SPWM inverter is adopted as five level inverter part, which can reduce the output voltage harmonics, improve power quality. Finally, the system simuration is debugged, simulation results demonstrate the effectiveness of this method. |
