摘　　要：为计算含单相变压器的配网潮流,本文从绕组等值电路入手,建立单相变压器的导纳矩阵模型。该模型考虑了变压器的所有节点,为一个四阶的方阵。最后,以10节点配网为例,实现含单相变压器的配网的潮流计算,而且通过方案比较得出含单相变压器的配网的电压质量高,损耗小,投资效益好。In order to calculate distribution power flow with single-phase transformer by winding equivalent circuit,admittance matrix model of single-phase transformer is built in this thesis.The paper states that the model considers all the nodes in the transformer for a fourth-order square.In addition,taking 10-node distribution network as an example,the calculation of distribution power flow with single-phase transformer is realized and through scheme comparison.Finally,the result is achieved that the Voltage quality of distribution network with single-phase transformer is high,its wastage is small,an its investment is in a good return.
