    Abstract：Based on load characteristics of cooling source，lighting，elevator and landscape lighting，etc. of commercial office buildings，in combination with statistical data of electricity consumption and characteristics of transformer，load calculation and transformer loss of commercial office buildings are analyzed with the conclusion that it is more effective in energy saving when less sets of large capacity transformers are used instead of more sets of small capacity transformers are used under the precondition that operation reliability is not affected. In addition，proposals are made in respect of related coefficients value in load calculation and transformer configuration of commercial office buildings.

    Key words：commercial office building；hourly electricity consumption；load calculation；load factor；dry-type transformer；no-load loss；load loss；cooling source load

 

    摘 要：从商务办公楼的冷源、照明、电梯、景观照明等负荷的特点入手，结合用电量统计数据及变压器的特性，对商务办公楼的负荷计算、变压器损耗进行分析，得出变压器在不影响运行可靠性的情况下采用大容量少台数比小容量多台数节能的结论，同时给出商务办公楼负荷计算相关系数取值及变压器配置的一些建议。
