某机场交通中心光伏发电系统并网运行分析

Analysis of Grid-connected Operation of Photovoltaic Power Generation System in an Airport Traffic Center

本文中的机场交通中心为玻璃穹顶,在其顶部布设有薄膜光伏发电系统并在其低压变电室低压侧并网发电.光伏发电系统的引入改变了现状配电系统,根据光伏系统的发电容量及并网形式进行短路及潮流计算,通过计算分析光伏系统对现状配电系统的影响并提出光伏发电系统低压保护要点.

An airport traffic center is a glass dome,in which a thin-film photovoltaic power generation system is installed and connected to the grid at the low-voltage side of its low-voltage substation.The introduction of photovoltaic power generation system has changed the current distribution system.According to the generation capacity and grid connection form of photovoltaic system,the short circuit and power flow calculation are carried out.Through the calculation and analysis of the impact of photovoltaic system on the current distribution system,the main points of low-voltage protection of photovoltaic power generation system are proposed.
