摘    要:针对微风、弱光条件下,风能、太阳能发电系统中储能设备效率低的问题,提出超级电容器阶梯式快速储能模型,并以超级电容器和锂电池为基本储能元件设计了阶梯式快速混合储能系统。基于超级电容器快速充放电的特点,将多个超级电容器串联,设计了一种阶梯式快速储能设备。利用锂电池能量密度大的特点,将阶梯式快速储能设备与锂电池结合,设计实现了一种阶梯式快速混合储能系统。该系统可实现充电、控制、保护和显示等功能。经过试验验证,该系统可解决风力、光伏发电机在微风、弱光状态下,电池低电压运行的储能问题,有效提高了微能的利用率。

关 键 词:超级电容器  阶梯式  储能  控制策略  测试

Abstract:Aiming at the low efficiency of energy storage devices of wind energy and solar power generating system under the condition of breeze and weak light, a model of stepwise super capacitor to storage energy rapidly is proposed, and a stepwise hybrid energy storage system which takes lithium battery and super capacitor as the basic energy storage components is designed. Based on the feature of super capacitor charge and discharge, an energy storage device is designed by setting multiple super capacitor in series connection. Using the feature of high energy density of lithium battery, this paper designs and implements a device combining stepwise fast storage system with lithium battery. This system realize the functions such as charging, controlling, protection, displaying and so on. The test verifies that the system can solve energy storage problem in low voltage operation under the condition of breeze and weak light and enhance the effectiveness of micro power source of utilization.
Keywords:super capacitor  stepwise  energy storage  control strategy  test
