直流市政供电系统的方案研究与设备应用

Scheme Design and Technology Research for Municipal DC Power Supply System

随着直流负荷日益增多,且直流电源占比越来越大,传统的交流供电网络已经难以适应现代智慧城市供电需求。针对市政供电不同场景,提出了多种直流配用电系统方案。给出了直流配用电系统设计方案,介绍了直流配用电关键设备,对典型的直流供电场景进行了分析,并列举了一些典型应用场景的拓扑结构。通过工程案例验证了该方案具有良好的应用和推广价值。

Nowadays,the DC load is increasing day by day,and the proportion of DC supply is getting higher,the traditional AC power supply network is hard to meet the demand of the modern smart city.This paper proposed several solutions of DC power supply for different scenarios of municipal power supply.This study presented the design scheme of the DC power distribution system.It introduced the crucial equipment for DC power distribution,analyzed the typical DC power supply scenarios,and enumerated the topology of some typical application scenarios.These engineering cases verify that the scheme has good application and promotion value.
