摘　　要：针对超大型数据中心专用变电站,对35~220 kV电压等级供电的变压器容量范围进行划分,取消柴油发电机组作为备用电源,由电网提供1~3路电源,分析电价政策尤其是两部制电价对供电方案的影响,计算主变压器和配电变压器单台最大容量,对比次级配电电压10~35 kV等级的经济性,提出变压器冗余配置及各电压等级电气主接线方案。建议A+级主机房配变M(1+2)配置,低压母线采用环形接线。For the special substation of the ultra large data center,the transformer capacity range of 35~220 kV voltage level power supply is divided,the diesel generator set is cancelled as a stand-by power source,and the power grid provides 1~3 power supplies,the impact of electricity price policy,especially the two-part electricity price on power supply scheme,the maximum capacity of the main transformer and distribution transformer is calculated,the economics of the secondary distribution voltage from 10~35 kV class is compared,and put forward transformer redundancy configuration and electrical circuit connection scheme at all levels voltage.It is recommended that the A+computer room distribution transformer is configured according to M(1+2)and the low-voltage busbar adopts ring wiring.
