光伏发电站消防设计研究

Research on Fire Protection Design of Photovoltaic Power Station

大中型光伏发电站由光伏阵列区和升压站组成。结合某光伏发电站工程情况,对其消防设计进行探讨。根据《光伏发电站设计规范》(GB 50797-2012)14.5.4条规定,含逆变器、就地升压变压器的光伏方阵区不宜设置消防水系统。根据光伏发电站工程的特点,光伏阵列区主要由电气设备组成,白天直流侧始终带电,不适合采用水消防。升压站内消防灭火设施主要为消防给水系统、灭火器配置系统和火灾自动报警系统。

Large and medium-sized photovoltaic power stations consist of photovoltaic array zones and booster stations. This paper discusses the fire protection design of a photovoltaic power station project. According to the code for design of pv power station（GB 50797-2012） 14.5.4, It is not suitable to set up the fire water system in the photovoltaic square zone with inverter and local boost transformer. According to the characteristics of photovoltaic power station project, the photovoltaic array area is mainly composed of electrical equipments. During the day, the dc side always has a point,and it is not suitable for fire protection water system. The fire extinguishing facilities in the booster station mainly include fire water supply system, fire extinguisher configuration system and automatic fire alarm system.
