摘要(Abstract):

为明确数据中心分布式供能系统可用性与经济性的匹配关系,以上海地区为例建立数据中心分布式供能系统模型,对其进行供能成本与供能可用性匹配关系探讨,结果显示:在上海地区现有条件下燃气分布式供能系统按照数据中心冷、电负荷进行装机匹配及系统设计时,系统综合能源利用效率最高,数据中心用能成本最低,且满足数据中心供能可用性要求。为提高数据中心供能系统可用性,对燃气分布式供能系统原动机进行冗余配备,配备1台备机即可满足数据中心供能系统可用性要求,且系统运行模式的调整对于系统可用性与经济性匹配关系不会造成根本性影响,此时限制数据中心分布式供能系统可用性的主要因素是供气管网的可用性,2台乃至更高数量的备用设备不会显著提高数据中心分布式供能系统的可用性,反而会提高系统单位供能成本,影响系统效益。
To formulate the matching of availability and economy of the distributed energy supply system in a data center, the paper, taking Shanghai as an example, establishes a model of the system in the data center and discusses the matching of energy supply cost and energy availability. The results show that under the existing conditions in Shanghai when the gas distributed energy system is designed and installed according to the cooling and electric load of the data center with the highest comprehensive energy utilization efficiency of the system, lowest energy consumption cost of the data center, and availability requirement of the energy supply of the data center met. To improve the reliability of the energy supply system in the data center, redundant allocation of the prime mover of the gas distribution system can meet the reliability requirements of the data center, and the adjustment of the system operation mode will not have a fundamental impact on the matching relationship between the system availability and economy. In this case, the main factor limiting the availability of the distributed energy supply system in the data center is the availability of the gas pipe, and two or more standby equipment cannot improve the availability of the distributed energy supply system of the data center, rather it will increase unit cost of energy supply of the system and affect the system benefits.
