直流配电的优势及低压直流系统故障分析和保护电器的选择

Advantages of DC Distribution and Fault Analysis on Low Voltage DC System and Protective Appliance Selection

随着分布式发电的大力发展和国家对新能源的大力扶持,越来越多的直流配电网和直流微电网项目纷纷落地。介绍了直流配电网回归的动力,以实际计算数据论证了直流供电相较交流供电的优势,并分析了直流配电系统中保护电器选择时的注意事项。

With the vigorous development of distributed power generation and the country’s strong support for new energy,more and more DC distribution network and DC microgrid projects have also landed.The return dynamics of DC distribution network was introduced.The advantages of DC power supply were demonstrated based on actual calculation data.The matters needing attention of selecting protective appliances were analyzed in the DC distribution system.
