城市住宅小区屋顶并网光伏发电系统的实现

为了促进光伏发电技术的商业应用,针对城市住宅小区的特点,提出了一种屋顶太阳能并网光伏发电系统方案.对屋顶太阳能电池组件的布置和分组串接技术、光伏系统外置设备的防雷保护技术、并网逆变器控制保护技术以及光伏系统负荷选择等问题进行了研究.结合浙江省慈溪市天和家园住宅小区屋顶太阳能并网光伏发电系统的应用,具体介绍了该系统所采用的技术措施及做法.实践表明,这些方法与措施能够满足要求.

Realization on rooftop grid-connected photovoltaic generating system in city housing district

In light of the characteristics in city housing district, a scheme of the rooftop grid-connected photovoltaic generating system was put forward, to promote the commercial application of solar photovoltaic power generation technology. The technologies such as the disposal and grouping in series of rooftop photovoltaic plants, lightning protection of the outer equipment of the photovoltaic system, control and protection of the grid-connected inverter and the load choice of photovohaic system were studied further. The technical measures and ways adopted by this system were illustrated by application of the rooftop grid-connected photovoltaic generating system at Tianhe housing district in Cixi city of Zhejiang province. Practice indicates that these measures and ways can satisfy the demands.
