北京奥运会国际广播中心临电并网切换

Paralleling Temporary Power at the Beijing Olympic Games

国家电网的相关要求不允许市电与用户单位设施中的临电系统并列运行。但由于奥运会的特殊性,奥运会期间国际广播中心设施的连续供电必须得到保障,在获得特别许可后,针对国际会议中心建筑采用了能满足相关供电需求的并列运行设计(并网切换)。本文概要分析了该操作模式,包括为提高用电可靠性而采用的开关设备的并网能力应满足并网需求,电力公司和其它参与单位对该模式的相关要求。

Paralleling temporary power generated within an independently owned facility and the utility power source is not permitted by the China State Grid. Because of the unique importance of the Olympic Games and the critical need for continuous power to supply the central broadcasting facilities during these games, special approval is obtained to design and provide a system suitable for these needs, but only for the single building which was to serve as the central broadcasting center and known as the International Broadcasting Center. Following is a brief insight and overview of some of the considerations made to provide the high level of reliability needed to add the paralleling capability to this switchgear, and meet the demands required by the power bureau and other key entities involved.
