独立光伏发电系统充放电控制策略

为了提高蓄电池的充电效率和延长蓄电池的使用寿命,提出了一种新的光伏发电系统充放电控制策略.该控制策略用双蓄电池代替以前的单一蓄电池,在充电过程中,蓄电池按照光伏系统提供的电流进行充电,根据蓄电池的充电电压特性和内部的温度特性来判别充电终止电压.同时,采用电压、温度微分模糊控制算法,既能防止光照强度、温度等外部环境发生变化而导致对蓄电池充电的提前切除,又可保护蓄电池的过充.仿真结果证明,该控制策略能显著提高蓄电池的充电效率和延长蓄电池的使用寿命.

Independent photovoltaic power generation system charge and discharge control tactic

In order to improve the efficiency of the battery charge and extend the battery life,developed a new charge-discharge control tactic which uses dual batteries to replace the previous single battery.In the whole process of charging with the photovoltaic system,the charging voltage of the termination based on the battery charge voltage and internal temperature characteristics;at the same time with voltage,temperature differential fuzzy control algorithm can prevent the external light intensity,temperature and...
