Abstract

Dynamic model of a wind generation system with a supercapacitor based energy storage system is developed. The supercapacitor system has been interfaced with the wind generation system through a STATCOM. Decoupled P-Q control of STATCOM is implemented by introducing suitable transformation on its injected current. The controller parameters are obtained through a search based optimization technique. The effectiveness of the STATCOM supercapacitor energy storage was examined for very low voltage situations. Simulation studies demonstrated that the STATCOM supercapacitor control can achieve significant withstand capability for reasonable low voltage duration. System transients are adequately suppressed and normal conditions are quickly restored.
使用基于超级电容器的储能系统的风力发电系统的快速低压穿越
建立了基于超级电容器储能系统的风力发电系统的动态模型。该超级电容器系统通过STATCOM与风力发电系统连接。通过对注入电流进行适当的变换,实现了STATCOM的P-Q解耦控制。通过基于搜索的优化技术获得控制器参数。研究了STATCOM超级电容器在极低电压条件下储能的有效性。仿真研究表明,STATCOM超级电容器控制可以在合理的低电压持续时间内获得显著的耐压能力。系统瞬态得到充分抑制,并迅速恢复正常状态。
