Abstract：Due to the large power consumption，large number of transformers and large installed capacity of the data center，keeping the transformers at the optimal state may reduce the electric energy loss of the transformers and facilitate the energy saving and consumption reduction of the data center. In combination with the actual load characteristics and operation states of the data center，the evaluation criteria and specific methods for the economic operation of transformer are concluded，which will be used in the analysis of economic operation of transformer in a Class A data center so as to put forward the corresponding optimization suggestions.

  摘要：由于数据中心用电量大、变压器数量多、装机容量大，将变压器控制在最佳经济运行状态下可以降低变压器电能损耗，对数据中心节能降耗具有重要作用。结合数据中心变压器实际负载特性和运行状态，经过一定的推导，得出变压器经济运行评判标准和具体评判方法，运用此方法对某A级数据中心变压器进行经济运行状态分析，进而提出相应的优化建议。
