北京南站供配电系统设计研究

Research on Design of Power Supply and Distribution System for Beijing South Railway Station

研究目的:北京南站是目前亚洲最大的火车客站,其开放的设计思路和大胆的构思彻底改变了以往旅客站房的设计风格和结构,同时也给供配电系统设计提出了新的要求,为此对其进行研究,提出可行的设计方案。研究结论:电力供应以外部电力系统供电为主,站区为了满足京津城际铁路和京沪高速铁路区间用电需求,设置10kV配电所及变电所,站房设置10kV变配电所;应急电源系统采用柴油发电机组和EPS相结合的方式,构成北京南站的主供电系统。并采用了三联供系统和太阳能光伏发电系统,当外部电源停电时可有效发挥其独立发电功能,为部分负荷提供电力保障。

Research purposes： The Beijing South Railway Station is the largest railway passenger station in Asia and its open design thought and boldness of concept thoroughly changed the traditional design style of station building and the building structure, so it brought about new requirement for design of power supply and distribution system. This paper gives an introduction to the research on the design of power system and presents a feasible design scheme.Research conclusions：The power supply chiefly depends on national power supply network, the 10 kV power distribution station and substation were installed in the station area for meeting the requirement of power supply to Beijing - Jianjin Intereity Railway and Beijing- Shanghai High -speed Railway, and the 10 kV power distribution station was installed for the station building. The diesel generator sets were installed as the emergency power supply along with the EPS. All these were composes of the power supply and distribution system for Beijing South Railway Station. In addition, the triple power supply and solar photovohaie generating system were installed and they could supply power for some customers when the outside power failed.
