摘要
对机场数据中心/机房的供电方案现状进行分析,现有UPS方案在可靠性、运行成本、PUE指标等多个方面存在弊端;以高压直流(HVDC)供电技术发展及应用为基础,分析机场各个级别机房内IT设备类别及机场主流使用的IT设备电源输入单元,阐述HVDC在机场数据中心/机房应用的可行性及带来的PUE降低、OPEX降低等经济和社会效益。给出4种适合机场实际应用的HVDC方案,分析方案实施时需要注意的重点事项;提出在绿色机场建设中引入HVDC方案将是趋势。
After analyzing the current status of electric power supply program in airport data center /computer room, it is found that the existing UPS program has the drawbacks in terms of reliability, OPEX, PUE indicators and other aspects. Based on the development and application of high voltage direct current （HVDC） power supply technology, the IT equipment types in all computer rooms and IT equipment power input units mainly used in airport are analyzed and the feasibility of the application of HVDC in airport data center/computer room and the economic and social benefits brought by the reduction of the PUE and OPEX are illustrated. Given four HVDC programs that suitable for the practical application of the airport, key issues which should be paid attention to in the implementation of the program are discussed and the idea that it is the trend to introduce the HVDC program in the construction of green airport is put forward.
