1. **文件性质与范围**:本文为《基于组件的离网太阳能能源系统设计指南》(2024年10月),涵盖纯光伏系统及光伏+燃油发电机混合系统的设计规范,适用于直流(DC)耦合和交流(AC)耦合配置。 2. **核心设计步骤**: - **负载评估**:需详细记录直流/交流设备的功率(W)、每日使用时间(h)及能耗(Wh),示例中AC负载最大需求223VA,日耗能1860Wh(湿季)。 - **电池选型**:根据自主天数(Days of Autonomy)、放电深度(DOD)及温度修正系数确定容量,示例中需匹配电池电压(12V/24V/48V)。 - **光伏阵列 sizing**:需考虑辐照量(如乌干达10°倾斜角数据)、温度衰减、污垢损失及老化因子(约0.46)。 - **逆变器匹配**:DC耦合系统需匹配控制器电压/电流;AC耦合系统需匹配PV逆变器的输入功率及电压窗口。 3. **混合系统特殊要求**: - 燃油发电机可作为备用电源(阴天时启用)或日常供电,需计算运行小时数及容量(如表8中降载因子)。 - 系统效率损失需纳入设计(DC耦合系统效率约80%,AC耦合约75%)。 4. **文档与合规**:需结合当地安装规范,提供系统原理图、物料清单及报价,并强调远程监控与维护的重要性。
