| 摘 要： | 系统频率控制能力随着电力系统风力发电渗透率的增加而降低,为了扩大风能比率,讨论了双馈风力发电机对系统惯性响应和频率控制的影响,分析了增加辅助惯性控制回路参数的作用。在此基础上,提出了一种利用双馈感应发电机更有效参与系统频率调节的新方法,该方法利用双馈感应发电机的快速功率控制能力,瞬时释放转子的部分动能,提供早期频率支持。仿真计算表明,新方法可以更有效地改善系统频率响应。

| Abstract: | To augment wind energy rates,we investigated the contribution of doubly fed induction generator(DFIG)to system inertial response and frequency regulation,and analyzed the influence of auxiliary loop parameters on the inertial response.Accordingly,we also introduced a novel algorithm to enhance the participation of doubly-fed induction generator(DFIG)in existing frequency regulation mechanisms.The proposed approach adopts the fast response capability associated with DFIG,and allows the kinetic energy stored ... |
