摘要：

为提高独立光伏系统的供电可靠性和光伏利用率，该文针对所选取设计地的气象数据，以及家用负载耗电量等条件，利用蓄电池容量计算式，计算系统中蓄电池放电小时率，并合理选择蓄电池型号。在最大功率跟踪条件下，根据光伏系统安装地的实际地理、气候、负荷情况，对发电系统中光伏电池阵列容量进行选择合理配置。利用Matlab中的Simulink工具箱构造小型太阳能发电系统，通过在光照强度和负载变化的条件下，研究蓄电池的响应特性和系统的功率平衡性能。仿真结果证实，合理选择蓄电池具备良好的充放电特性，能快速调节系统输出功率满足负载需求。

Abstract: In order to improve the power supply reliability and photovoltaic efficiency of the independent photovoltaic system, the battery capacity calculation formula is used to calculate the battery discharge hourly rate, and the rationally select battery type. In the formula, the selected weather data and the household load consumption are considered. Under the condition of maximum power tracking, according to the actual geographic, climatic and load conditions of the installation site of the photovoltaic system, the capacity of the photovoltaic cell array in the power generation system is selected and rationally configured. The household solar power generation system is constructed by using the Simulink toolbox in Matlab, which can be simulated by changing the photovoltaic cell array and the capacity of the battery in the system. The response characteristics of battery and the power balance performance of the system are also discussed. The simulation results confirm that reasonable selection of battery will contribute good charge and discharge characteristics, and it can quickly adjust the output power of the system to meet the load demand.
