Abstract

There are lots of issues existed with the Power Supply System in DC Building, and it is controversial as these issues have not been solved completely. In recent years, worldwide attention has been focused on proposing the standards of “HVDC power supply system” or “up to 400Vdc power feed system” following with the development of the power supply system in data center. Many attentions from the worldwide research organizations or institutions have pointed out that these standards can be applied with DC Building. In this paper, the standards of the main organizations and institutions on HVDC power supply system are introduced. Then some definitions of the issues among the standards of these organizations or institutions are analyzed and compared. The requirements for designing the power supply system in DC Building are discussed based on the above issues, including the system topology and the key power electronic converters interfaced to the system. The analysis can be referenced for designing the equipment of the Power Supply System in DC Building and helpful for popularizing the DC Power Supply Technology.

直流建筑供电系统设计要求的分析与研究

直流楼宇供电系统存在着许多问题，这些问题还没有完全解决，引起了广泛的争议。近年来，随着数据中心供电系统的发展，国际上纷纷提出“高压直流供电系统”或“高达400Vdc供电系统”的标准。国际上许多研究机构的关注都指出这些标准可以应用于DC建筑。本文介绍了主要组织机构对高压直流供电系统的标准。然后对这些组织或机构的标准中问题的定义进行了分析和比较。在此基础上，讨论了直流楼宇供电系统的设计要求，包括系统拓扑结构和与系统接口的关键电力电子变换器。分析结果可为直流建筑供电系统设备的设计提供参考，对推广直流供电技术有一定的帮助。
