河北某数据中心三联供电气系统的电气设计

The electrical design of the triple electricity supply system of a data center in Hebei Province

通过方案分析了三联供电气系统与数据中心电气系统的并网运行。发电机控制系统,根据装设于并网点的方向,判断元件和数据中心实时冷负荷需求,控制发电机发电量。发电机的发电量在不超过数据中心用电负荷的情况下,动态地调节输出,满足数据中心的冷负荷需求。当发电机发电量接近数据中心用电负荷时,开启电制冷机进行调峰制冷,以此获得一个能源利用效率最高的运行方案。

Through scheme analysis,the triple power supply electrical system and the data center electrical system are connected to the grid for operation,and the generator control system judges the real-time cooling load demand of the components and the data center according to the direction installed in the grid point,and controls the generation capacity of the generator.When the generating capacity of the generator does not exceed the power load of the data center,the output can be adjusted dynamically to meet the cooling load demand of the data center.When the generating capacity of the generator is close to the power load of the data center,turn on the electric refrigerator for peak load regulation and refrigeration,so as to obtain an operation scheme with the highest energy utilization efficiency.
