数据中心供电系统的新技术应用研究

随着IDC及云计算的快速发展，如何建设绿色节能和经济高效的数据中心已经成为国内各大运营商及政企关注的重点。传统UPS供电系统因效率低、能耗高、后备铅酸蓄电池不够绿色环保、投资效益较差等弊病一定程度上促成了各种新的替代供电技术的出现。针对模块化UPS、高压直流、DPS、飞轮UPS及动态UPS供电技术共五种新供电技术，重点从系统工作原理、实际应用模型、优劣和效益、建设投资等多个角度进行了深入的对比分析和研究，旨在为下一代绿色数据中心供电系统的规划建设提供决策依据。

Application Research of New Technology on Data Center Power Supply System

with the rapid development of IDC and cloud computing, how to build a green energy-saving ,economical and efficient data center has become the major concern of domestic telecommunication operation business ,government and enterprises. The traditional UPS power supply system has some disadvantages, such as low efficiency, high energy consumption, reserve lead-acid battery with not green and environmental protection, poor investment benefit,which bring about variety of new alternative power supply technology to some extent. Based on modularized UPS, HVDC, DPS, flywheel UPS and dynamic UPS, the paper gives comparative analysis and research on this five new power supply technology, including system working principle, application model, advantages a d disadvantages, benefit and construction investment and other perspectives, thus provides the decision basis for the planning and construction of next generation green data center power supply system.
