摘要
直流电源系统直接关系到电网的稳定运行和设备安全,也是集中式地面光伏电站在事故和紧急情况下的重要电源供给。针对当前光伏电站直流系统的研究较少,以50 MWp集中式地面光伏电站为例,全方位的探讨了直流电源系统的总体设计,详细研究了蓄电池组的个数、容量计算,并对直流电源系统的布置、接地防护等进行分析,并提出了防范措施,可作为大中型地面集中式光伏电站升压站直流系统设计的依据。
The DC power system directly affects the stable operation of the power grid and the safety of equipment.It is also an important power supply for centralized ground photovoltaic power stations in case of accidents and emergencies.While few researches are done on the DC power system of photovoltaic power stations.The overall design of the DC power system for 50 MWp centralized ground photovoltaic power station is discussed in detail,including the calculation of the number and capacity of the storage battery packs,and the layout,grounding protection and preventive measures of the DC power system.It can be useful reference for the design of the DC system of booster station in large and medium centralized ground photovoltaic power stations.
