摘　　要：配电网通常为多相且呈辐射状。为了便于进行潮流计算及优化,提高计算效率,本文推导了基于辐射配电网的一种线性近似潮流方程。该方程可以方便的应用于配电网的重构、恢复以及最优潮流等问题中。采用IEEE 13,34,37,123节点标准配电测试系统进行测试,验证了所提方法的准确性。Distribution networks are usually multiphase and radial. To facilitate power flow computation and optimization and improve computational efficiency,a linear approximation of the power flow equation was proposed based on the radial distribution network. This equation can be easily used for the problems to reconstruct the distribution network reconfiguration,as well as restoration and optimal power flow. Case studies of the IEEE 13,34,37,123 node test feeders show the effectiveness and exactness of the proposed method.
