| 摘 要： | IEEE相关标准对分布式发电系统注入电网的谐波电流作出了严格的限制.通过分析电网低次谐波电压对双馈风力发电系统定子电流总谐波畸变率(THD)的影响发现,传统基于定子电压定向的双馈风力发电系统并网发电矢量控制策略在大容量变流器控制中存在着缺点,即因为控制带宽低而无法有效抑制电网低次谐波电压引起的定子谐波电流,从而在较大工...

| Abstract: | IEEE standards have defined the maximum permitted harmonic current injected to the grid by distributed resources.According to the analysis of the stator current total harmonic distortion(THD) influenced by grid harmonic voltage in doubly-fed induction generator(DFIG),there is a drawback of grid-connected vector control for DFIG in high power converter.Due to the low control bandwidth,this control strategy cannot suppress the harmonica current of stator.So the power quality cannot fulfill the IEEE standards ... |
