摘要
为提高STATCOM装置工作的可靠性,减小直流侧电压变化对输出的影响,基于Z源逆变技术,提出一种新型的Z源STATCOM拓扑结构。新型的Z源STATCOM是通过在传统的STATCOM装置的直流侧输入端增加Z源网络而成,克服了传统STATCOM装置易受直流侧电源电压影响的不足,增加了STATCOM装置直流侧电源的选择灵活性,提高其工作的可靠性。使用电力电子仿真软件Simplorer进行仿真,通过对比传统STATCOM与Z源STATCOM在不同工况下的补偿效果,证明Z源STATCOM在直流侧电源电压变化的情况下,工作稳定可靠。
In order to enhance the reliability of STATCOM devices, reduce the influence of the voltage of DC-side on the output, the novel Z-source STATCOM is proposed based on Z-source inverter technology. The new Z-source STATCOM is formed by adding the Z-source network at the DC input side of traditional STATCOM device. It overcomes the shortcoming of traditional STATCOM devices that are vulnerable to the voltage of DC- side, increases the choice flexibility of the power at DC-side of STATCOM device, and improves the reliability. Simplorer 7. 05 software is used as a tool of simulation. The result of the comparison between the Z-source STATCOM and traditional STATCOM shows that Z source STATCOM is stable and reliable when the DC-side voltage is unstable.
