摘　　要：为了更好地处理贯通同相牵引供电系统中的潮流分析问题,本文提出了一种避免复杂矩阵计算的简单潮流算法。通过探讨贯通同相牵引供电系统中的等效模型,将同相补偿装置等效为受控电流源后采用戴维南定理对该等效模型进行分析;通过推导贯通同相牵引供电系统中列车节点、牵引所端口的电流分配规律进行单列车状态下供电系统的快速潮流计算,再通过叠加定理处理多列车状态下的潮流计算。In order for better resolution of problems for analyzing the power flow in through co-phase traction power supply system,the paper puts forward a simple power flow algorithm to avoid the complex matrix computation.By discussion of equivalent model in the through co-phase traction power supply system,the co-phase compensation device is equivalent to a controlled current source,and the equivalent model is analyzed by Thevenin theorem;by rapid power flow calculation for power supply system under condition of single train running on the basis of train node and current distribution regularities of port of traction substation in the though co-phase traction power supply system,and the power flow calculation under condition of multi-train running is then processed.
