摘要
对独立光伏发电系统中铅酸蓄电池的充电特性进行了分析,提出根据蓄电池端电压的变化预测蓄电池内过充电反应状况,采用变电流充电方法进行快速充电。根据负载和蓄电池的变化调节光伏发电系统的工作状态,优化控制充电过程。仿真研究表明该方法能够避免蓄电池发生过充电和最大限度地避免欠充电,从而延长其使用寿命,同时提高了光伏系统的工作效率,实现系统优化运行。
The charge characteristics of lead-acid battery for photovohaic （PV） power system are analyzed. A charge control strategy, which controls the charge process by means of regulating the operation of PV system in accordance with the variable of load and battery terminal voltage that forecast overcharge state is presented in order to perform fast charge. Simulation results show that the suggested control method can avoid overcharge and under charge as possible, so the lifetime of battery can be extended. At the same time, PV system achieves optimal operation as well as improving the efficiency of system.
