直流配电网的发展及优势分析

Research on the Development and Advantage of DC Power Distribution Grid

随着分布式电源的快速发展及直流负荷的迅猛增长,交流配电网已经不再适应未来电网的发展,而直流配电网的优势日益显现。文中对直流配电网发展历程进行了回顾,并以美国及日本的直流配电网为例对其结构进行了介绍,然后对交流配电网的弊端及直流配电网的优势进行了重点阐述,结果表明,直流配电网优于交流配电网,具有经济、高效、可靠等诸多优势,是未来电网的发展趋势。

With the rapid development of distributed power supply and the rapid growth of DC load, the AC distribution grid is no longer suitable for the development of the future power grid, and the advantages of DC power distribution grid is becoming more and more obvious. The development trend of the future power grid, the development process of the DC distribution grid were reviewed, and in the United States and Japan, DC power distribution grid as an example on the structure are introduced, and advantages of AC power distribution of malpractice and DC distribution grid has carried on the key elaboration. The result in this paper shows that, DC power distribution grid is better than that of AC power distribution grid, with economic, efficient, reliable, and other advantages.
