光伏幕墙是玻璃幕墙的一种特殊形式,是以幕墙的形式将光伏组件安装在建筑物上,使它既具有玻璃幕墙的建筑物围护结构功能,又可以利用太阳能发电的双重用途。本文所述工程中光伏发电系统的并网方式采用不可逆流并网发电,即光伏并网系统所发的电由本地负荷消耗,多余的电不允许通过低压配电变压器向上级电网逆向送电。
Photovoltaic curtain wall is a special form of glass curtain wall, is the curtain wall in the form of photovoltaic modules installed on the building, making it both glass curtain wall building envelope structure function, but also can make use of dual-use solar power generation. The grid-connected method of photovoltaic power generation system in this paper adopts non-reversible flow and grid-connected power generation, that is, the electricity generated by the grid-connected photovoltaic system is consumed by the local load, and the excess power is not allowed to reversely transmit power to the upper-level power grid through the low-voltage distribution transformer.
