摘　　要：随着风力发电、光伏发电、电池储能等新能源技术的发展,以及电脑、显示器、LED照明、变频空调和电动汽车等可用直流供电设备的普及,直流供电在建筑中的应用受到了越来越多的关注。建筑直流供电系统线路损耗小、电能质量好、运行效率高、方便新能源发电与储能系统的接入、不存在谐波和无功补偿等问题,可提供安全、灵活、高效的供电服务,有着广阔的应用前景。本文从建筑直流供电系统结构、电压等级、接地与保护、分布式储能和新能源发电系统接入、负载兼容性和关键设备等几个方面对建筑直流供电系统进行了综述,梳理提出了下一步需要深入解决研究、解决的问题。with the development of wind power generation, photovoltaic power generation, battery energy storage and other new energy technologies, as well as the popularity of available DC power supply equipment such as computers, displays, LED lighting, frequency conversion air conditioning and electric vehicles, the application of DC power supply in buildings has attracted more and more attention. Building DC power supply system has the advantages of low line loss, good power quality, high operation efficiency, convenient access of new energy power generation and energy storage system, and no harmonic and reactive power compensation problems. It can provide safe, flexible and efficient power supply services, and has broad application prospects. This paper summarizes the DC power supply system of buildings from the aspects of structure, voltage level, grounding and protection, distributed energy storage and new energy generation system access, load compatibility and key equipment, and puts forward the problems that need to be solved in depth.
