5kW家用光伏并网发电系统设计

5kW Home Photovoltaic Grid-Connected Power Generation System Design

我国是发展中大国,工业发展与国民用电对能源的依赖性非常大,太阳能不仅清洁无污染而且是可无限再生的一种能源。对太阳能的利用推动了光伏发电产业的发展,小型的家用光伏发电能直接惠利于民,在近年来受到了广泛关注。设计装机容量为5 kW的光伏并网发电系统,足以满足一般家庭的生活用电。通过简单介绍光伏发电产业的现状和前景,设计了光伏并网发电系统的各个模块,包括光伏电池的原理、电池组件的设计、主电路的设计以及控制系统的设计。

China is a large developing country,industrial development and national electricity are very dependent on energy.Solar energy is not only clean and pollution-free,but also an unlimited renewable energy.The use of solar energy promotes the development of photovoltaic power generation industry,and small household photovoltaic power generation can directly benefit the people,which has been widely concerned in recent years.This paper designs a photovoltaic grid connected power generation system with an installed capacity of 5 kW,which is enough to meet the domestic power consumption of ordinary families.In this paper,the status and prospects of photovoltaic power generation industry are briefly introduced,and each module of photovoltaic grid connected power generation system is designed.Including the principle of photovoltaic cells and battery module design,main circuit design,control system design.
