温室的高能耗有碍于其发展,引入可再生能源是温室节能减排的有效举措。本文介绍了一种将光伏发电及控制技术应用于温室的方法,太阳电池组件直接安装在温室室顶,通过与市电并联及少量蓄电池配置保证供电可靠性和功率平滑性,并基于无线通信技术实现温室环境因子参数的采集和远程监控。该系统不但能够根据设定目标自动地调节温室内部环境,而且能够监视整个系统的能量流动情况。温室运行结果表明,该系统能够满足冬季温室用电,并部分解决夏季温室用电,大大减少对化石能源的需求,达到节能减排的效果。
The development of greenhouse is limited by its high energy consumption, application of renewable energy in greenhouse is an effective way for energy saving. In this paper, an approach of photovoltaic(PV) power generation and control technology is applied to greenhouse. The PV panels were installed directly on the top of the greenhouse. The PV system generates power for the greenhouse by parallel with the mains and a small amount of batteries were applied to ensure the reliability and smoothness of power supply. Besides, based on the wireless communication technology, a remote monitoring system was developed to acquire the greenhouse environmental factors and demonstrate relative data. The proposed system not only adjusts the environment parameters of greenhouse automatically according to the reference value, but also monitors the energy flow of the entire system. Results show that the system satisfies the needs of power for greenhouse in winter, as well as the partial in summer, thus greatly reducing the need for fossil fuels and achieves the goal of energy saving.
