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.
