| 摘 要： | 超级电容器是风电潮流优化控制系统中的关键储能元件之一,而高效可靠的串联均压策略是其实现中大功率场合应用的前提,为较好地实现均压效果,引入了一种超电容电压均衡控制策略的模型,并在此基础上提出了一种新颖的超电容电压均衡方法—相邻电感储能电压均衡法。该方法实时检测超电容组中各电容器电压,以电感为能量传递媒介,以半导体开关管为控制开关,将电压高的电容器能量转移到电压低的电容器中,实现了各超电容器的电压均衡。在详细介绍了该方法的工作原理后,给出了控制开关占空比的调节规律和电感参数的设计原则。最后,对两组串联超级电容器模块分别进行了仿真和实验,结果表明该方法极大地改善了超电容模块的电压一致性,电压均衡速度快、精度高,在风电潮流优化控制系统中有较高的应用价值。
