变电站变压器经济运行方式的研究

基于变电站变压器组合运行技术特性的分析，提出了计算变电站多台变压器组合经济运行方式的“最小交点损失法”。这种方法可直接推广应用于三绕组变压器组合经济运行的情况。实际应用结果表明，本文的方法简单、实用、有效。

Study of Economic Operations of Substation Transformers

Based on the technique characteristic analysis of substation trandformer combination operation,an effective method called cross point minimum loss is presented to decide the operation mode of transformers in a substation,by which the active power loss of substation is minimized.The method is easy to extend for threewinging transformer combination operation.Practical use shows that the proposed method is simple and effective.
