摘　　要：配变轮换实现了被更换可用配变的再次利用,能有效降低配变改造成本.通过引入有向图,利用有向边准确描述了配变增容和减容的需求,并基于有向图单向连通路径、最大环路径和最长路径等提出配变轮换序列自动生成方法.算例分析表明,所提方法能求解"阶梯式"和"推磨式"配变轮换序列,能分析轮换序列中配变新增数量、闲置数量以及拆装次数,有利于分析配变轮换成本.Distribution transformer(DT)rotation could achiev the re-use of the replaced distribution transformer in the life cycle,and reduce the investment of DT upgrade.With the directed-graph,the requirement of increase and decrease of the DT capacity was exactly described by directed-edge.And an auto solution for transformer rotation arrangement was presented based on the connectivity path,maximum loop and maximum path in directed-graph.From the example,the proposed method could solve the transformer rotation arrangement of“mill”and“step”pattern,and could analyze the quantity of new DT,the quantity of idle DT,and the times of DT installation or uninstallation.That would be helpful to calculate cost of the DT rotation.
