【摘要】 数据中心的冷、电负荷需求量大,全年负荷稳定,且冷电比与天然气分布式能源系统的供电供冷比例接近,适宜采用分布式能源系统。通过对某数据中心的用能需求进行分析,在保证数据中心安全用能的基础上,设计了规模合适的分布式能源站方案,即内燃机+烟气-热水型溴化锂机组+离心式电制冷机+蓄冷罐模式,实现了数据中心绿色低碳运行。评价结果显示:天然气分布式供能方案是建立基于低碳能源的供能模型,充分利用峰谷电价差,降低运营成本,提高经济性;能源站总体经济性可行,能耗低、碳排放量低、节能减排效果佳,在数据中心周边有稳定可靠的廉价天然气气源、碳交易价格合适时,该方案具有一定的推广意义。更多还原

【Abstract】 The demand for electricity and cooling load in data centers is large and steady.The cooling-to-power ratio of data centers is close to that of gas-fired distributed energy systems,which means distributed energy systems are suitable for data centers. Through the analysis on the power demand of a data center,a scheme of a distributed energy station with an appropriate scale which can ensure the safe power supply to the data center is designed. The scheme takes internal combustion engine,gas and hot water type LiBr-H2 O refrigerator,centrifugal electric refrigerator and cold storage tank,which can realize the green and low-carbon operation of the data center.The gas-fired distributed power supply scheme is made based on a low-carbon energy-supply model. The evaluation results show that this scheme makes full use of the offpeak electricity,reduces operating costs and improves the economy.The power station is economically feasible,with low energy consumption,decent energy saving and emission reduction effect.This scheme is practicable for the data centers wherever there are reasonable carbon trading prices and stable,reliable and cheap gas sources nearby.更多还原
