为了确定配电网中压馈线之间的负荷转供情况，结合线路的最大负荷电流、允许载流量和多种约束条件，提出了基于“N-1”准则的负荷转供实用测算和分析方法。在了解馈线联络情况的基础上，确定由单馈线或多馈线承担负荷转供的可能性；在满足多种约束条件下，计算、分析并获得馈线首端故障后的转供负荷容量和多种转供方案。通过对变电站各回馈线转供数据进行汇总，可以得出变电站不同故障情况下的负荷损失率。经过实际配电网转供的工程应用，验证了测算分析方法的实用性和有效性。

To determine the load transfer between medium voltage feeders in distribution network, combining with the maximum load current and allowable peer ampacity of the lines and some constraints, a practical method is proposed to calculate and analyze the load transfer based on N-1 security criterion. On the basis of understanding the basic connection relation between the feeders, the possibility of the load transfer is determined, which might be supported by a single feeder or multiple feeders. The transfer capacity and the transfer solution schemes to meet the constraints could be calculated, analyzed and obtained when a feeder starting terminal was in failure. The load loss rate under different fault conditions of one single substation could be obtained by summarizing all the transfer information of the lines from the substation. The practicability and the effectiveness of the method have been verified through the practical engineering application in a real distribution network.
