摘要
未来电力系统将以区域交流输、配电网络和直流网络共存的形式存在,直流配电作为直流生态系统中的中间部分,起到以直流的形式承接高压输电网并向负载馈送电力的关键作用,引起人们的广泛关注。在直流配电网发展驱动力分析的基础上,分别介绍直流配电在国内外的发展现状,提出未来交直流混联电力系统、直流配电电压等级序列、直流配电典型应用场景及网络架构3个方面的初步设想。并详细介绍德国亚琛大学10k V校园直流配电网的网络拓扑结构。勾勒出未来直流配电网的轮廓,推动能源互联网的发展,为构建新型智能配电网提供创新思路。
The future power system will be in the form of regional alternating current（AC） transmission, AC distribution network and direct current（DC） network coexistence. As the middle part of the whole DC system, DC distribution network plays a key role in the connection of high voltage power transmission network and power loads. On the basis of analyzing the drives of DC power distribution network, the paper introduced the development status of DC power distribution in China and abroad. Then the preliminary ideas of three aspects of the future of the power system, the DC distribution voltage level sequence, the typical application scenarios of the DC distribution and the network architecture were presented. This paper also introduced the network topology of the 10 k V DC pilot project of Aachen University campus in Germany. The outline of the future DC distribution network, the development of the energy internet, and the innovative ideas for the construction of new intelligent distribution network were also introduced.
