独立光伏发电系统广泛应用于航标设备,通常需要储能系统来保证供电的稳定性和持续性。为了吸收光伏电池发出的脉动功率,从而抑制直流电源的电压波动,并满足向负载提供短时大功率的需求,提出了采用超级电容器和蓄电池混合储能方案,并进行了充放电系统分析,针对超级电容和蓄电池充放电特点,提出了充放电控制策略。
Independent photovoltaic power generation systems are widely used in aids to navigation equipment, usually require energy storage system to ensure the stability and continuity of power supply. In order to absorb the pulsating power emitted by photovoltaic cells and thus suppress the voltage fluctuation of the DC power supply and meet the demand of providing short-time high power to the load, a hybrid energy storage scheme using supercapacitor and battery is proposed and the charge-discharge system is analyzed. Super capacitor and battery charge-discharge characteristics, proposed charge-discharge control strategy.
