摘要

直流输电相关技术的发展使得构建一个多级直流网络配电系统成为可能。首先详细分析了直流配电电压等级序列制定的基本原则与主要约束条件。在分析各电压等级直流配电能力基础上，以负荷需求为基本出发点，综合考虑相关设备制造水平、电网结构优化需要等方面，提出了一套高压、中压、低压以及超低压相互配合的直流配电网电压等级序列。最后通过具体算例，简要分析了多级直流配电的经济性。

Abstract

With the development of DC power transmission technology

it is possible to develop a multi-level DC distribution system. This paper firstly analyzes the basic principles and main constraints to design DC distribution network voltage class series. Based on the analysis of DC power distribution capacity with each voltage level

a set of DC distribution network voltage class series is proposed in which high voltage

medium voltage

low voltage and ultra-low voltage cooperate with each other. The related equipment manufacturing level and power grid topology optimization should be taken into account in voltage class series based on load demand. Finally

the economy of multi-level DC distribution is briefly analyzed. This work is supported by National Natural Science Foundation of China (No. 51277083).
