摘　　要：在离网型风电系统中,由于风力和风向的不断变化,系统输出功率会产生脉动的波动,进而影响系统的稳定性。储能系统能够在一定程度上平滑系统输出的功率波动,改善发电系统输出功率的稳定性。简要地叙述了应用于离网型风电系统中的储能技术研究现状,提出了一种使用超级电容器和蓄电池并联的复合储能系统,在PSIM软件中建立了该系统的模型,同时进行了系统实验的回路制作研究。仿真实验结果表明,系统对频率为0.2~9 Hz的输入波动具有很好的抑制效果。In wind power generation system, the output power will occur pulse wave which will influence the stabilization of the whole system, due to the variation of the wind direction and wind power. The energy storages system can smooth the fluctuation of output power and improve the stabilization of the generate electricity system. This paper analyzed the development of the compose energy storage system in the wind power generation system, and then proposed a kind of the composite energy storage system, established the model of this composite energy storage system in the PSIM. Through simulation experiment, it is showed that the system can easily smooth the fluctuation, when the frequency of the input power is 0.2-0.9 Hz, and the reality control and drive circuit of the composite storage system was tested.
