Abstract: 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.

Keywords: photovoltaic power generation; short circuit; power flow analysis; distribution protection;
