摘要
配电网中拥有众多变压器且容量大,进行配电变压器的节能降耗研究是很有必要的.对某商用大楼的配电变压器能耗现状进行分析,通过理论计算,从运行方式、减少三相不平衡、调整运行电压、减小负荷波动、无功补偿、更换变压器等的节能效果进行对比,提出了配电变压器节能优化改造方案.
Abstract
It is necessary to conduct the energy-saving research of the large-capability transformers used in distribution network in great numbers.This paper analyzes the energy consumption of the distribution transformers in a commercial building.Through theoretical calculation,the energy-saving effects are compared in terms of operation mode,three-phase load unbalance reduction,running voltage adjustment,load fluctuation reduction,reactive compensation and transformer replacement.Finally,the energy-saving optimal retrofit scheme for distribution transformers is presented.
