摘要
介绍了一个与建筑结合的小型光伏微网系统的实现方法,以蓄电池双向逆变器为核心,确定了主从型光伏微网系统的设计方案并加以实现。结合具体应用地点的气象数据、具体建筑的空间及用电负荷情况,确定了以年发电量最大为目标的各部分光伏组件的安装容量。搭建了光伏发电系统和能源管理系统,完成系统实时监测和数据记录功能并实现了微网系统运行模式切换功能。在此基础之上,实现了光伏降温水循环系统,解决了由于光伏背板升温引起的峰值功率下降而造成的系统发电效率下降的问题。实验测试结果表明,该系统能稳定运行于联网模式和孤岛模式,改进的光伏电池板降温水循环系统提高了系统发电总量。
The design of a small-scale building integrated photovoltaic micro-grid system was presented, which was a master-slave system with bi-directional battery inverter as the core of the system. According to the specific meteorological data, construction space and electricity load, the maximum annual generation capacity and various parts of the PV modules installed capacity were simulated. A photovoltaic energy system and management system were established, which had the function of real-time data monitoring and logging, and switched different micro-grid operation mode. On this basis, the photovoltaic cooling water system was presented to solve the decline in peak power generation of the system caused by the increase of the temperature of the photovoltaic panel. Experimental results show that the stability of the system can run in networked mode and island mode, and cooling water system of photovoltaic panels improve the total system power generation.
