摘要 超级电容的功率密度大,循环寿命长,很适合与能量密度大的蓄电池相结合,共同组成独立式光伏发电系统的储能部分。在此分析比较了两种储能器件的各项参数,针对光伏发电系统的特点,提出了一种应用于蓄电池与超级电容混合储能系统的充电控制方案。通过监视系统供电状态,减少蓄电池不必要的接入,达到延长蓄电池循环寿命的目的。实验结果表明,蓄电池与超级电容混合储能明显提高了系统的瞬时功率输出,降低了蓄电池的电流脉动,并减少其充放电循环次数,有效延长了蓄电池的使用寿命。 Ultracapacitor has the characteristics of high power density and long cycle life.A methodology of ultracapac-itor and battery hybrid energy storage in stand-alone photovoltaic system is proposed.According to the comparative test of the storage system with ultracapacitor or not.Use of ultracapacitor enhances the instantaneous power of the entire system,lower the pulsating current of battery.By reducing the number of recharge cycles of battery,new methodology lengthens the life of battery.
