摘　　要：由于交流配电网的电压跌落、电网谐波、电压不稳定等问题,直流配电网成为近年的研究热点。相较于交流配电网而言,直流配电网铺设线路成本较低,在输电过程中线路电能损耗有所减少,拥有较大的供电容量以及可靠性,同时较为环保。能够有效解决电能质量问题、易于分布式电源、储能电池接入等特点,得到了供电企业和研究学者的广泛重视。对直流配电网的拓扑结构、优势和特点、关键技术环节等领域进行了全面的阐述,对直流配电网在中国的发展进了总结和展望。The frequency of voltage drop, power grid harmonics, and voltage instability and so on in AC power distribution network is gradually increasing. The domestic and foreign research scholars now turn to the new field of DC power distribution network. Com-pared with AC power distribution network, DC power distribution network has the advantages of low cost, low transmission loss, high power supply capacity, high reliability, environmental protection, high power quality, easier for distributed power and energy storage to access and other characteristics. In this paper, the topology, advantages and characteristics, key technology of DC distribu-tion network are described, and the development of intelligent DC power distribution network in China is summarized and prospected.
