Abstract The application of photovoltaic power generation system as emergency power supply in civil buildings should be used with grid-connected photovoltaic power generation system with energy storage devices. Configuration of the storage battery capacity should meet the emergency loads. Comprehensive economic and technical analysis should be made in determining whether a photovoltaic power generation system is appropriate as an emergency power supply.

Key words　Grid-connected photovoltaic power generation system Emergency power supply Reliability Storage battery Emergency lighting

摘　要　民用建筑中利用太阳能光伏发电系统作为应急电源应选用有储能装置的并网光伏发电系统。蓄电池组容量应按满足应急负荷需要配置。光伏发电系统是否宜作为应急电源应作经济技术方面的综合分析。
