| 中文摘要: |
| 蓄电池的充放电管理一直是其控制器的关键.为提高光伏系统中蓄电池的充电效率,延长蓄电池使用寿命,采用脉宽调制的三段式充电策略(快速充电、脉冲式恒压充电及浮充电),利用MATLAB/Simulink软件平台对整个系统进行建模并仿真,为光伏系统中蓄电池的充放电管理提供了参考与依据.仿真结果验证了系统仿真模型的可用性和通用价值以及蓄电池控制策略的可行性和合理性,并表明在此蓄电池管理策略下可提高蓄电池充电效率,延长其使用寿命. |
| 英文摘要: |
| Battery charge and discharge management is always the key issue of its controller. To improve the battery charging efficiency of the photovoltaic system, and to extend the battery life, the charging strategy based on three-pulse-width modulation (fast charging, constant voltage charging with pulses and float charging) is employed in this paper. And the model of the entire system using MATLAB/Simulink software is established to give a reference for battery management in the photovoltaic system. The simulation results verify the feasibility and reasonability of the system simulation model and the battery control strategy. The results also indicate that the battery charging efficiency can be improved with this strategy, and the battery life can also be extended. |
