摘要 近年来,电气化铁路迅速发展,牵引供电系统承担着将电能从电力系统输送到高速行驶列车的任务。因此,研究和精确建立牵引供电系统数学模型是十分必要的。本文基于Carson理论和电磁场理论对牵引网的串联阻抗矩阵和并联导纳矩阵进行计算,并结合多导线等值简化原则实现阻抗和导纳矩阵的降阶处理,分别对牵引供电系统内器件建立Matlab数学仿真模型,实现对牵引供电系统精确建模。 In recent years, electrified railways have developed rapidly, and the traction power system has been tasked with transporting electricity from the power system to high-speed trains. Therefore, it is necessary to study and accurately establish the mathematical model of traction power supply system. Based on the theory of Carson and electromagnetic field theory, a series of traction network series impedance matrix and admittance matrix of parallel calculation, and combined with multiple conductor equivalent simplification principle of order reduction treatment of impedance and admittance matrix, respectively to the traction power supply system components to establish the mathematical simulation model of Matlab can realize accurate modeling of the traction power supply system.
