多列运行列车的铁路轨道的电气建模是复杂的，由于解决的功率流的困难。列车的位置、速度和加速度都是瞬时变化的，这使得系统是非线性的。此外，变电站的不可逆性也是导致系统非线性的另一个原因。轨道交通系统的这些非线性特性使得电力系统的潮流分析更加复杂。本文采用一种简单的电气化铁路建模方法，避免了求解潮流的复杂算法。该方法主要依赖于建模的机械和电气特性的完整的轨道系统使用的仿真工具Simscape，它已被开发的MathWorks。该模型能够提供轨道电压和列车电压。通过实施储能系统（ESS），可以通过有效控制轨道电压和列车接触电压来提高电气化铁路的能源效率。
The electrical modelling of rail tracks with multiple running trains is complex due to the difficulties of solving the power flow. The trains' positions, speed, and acceleration change instantly which makes the system nonlinear. Additionally, the nonreversible substations are another reason for the nonlinearity of the system. These nonlinear characteristics of the rail system make the power flow analysis more complicated. In this paper, a simple method for modelling electric railways has been used to avoid complicated algorithms to solve the power flow. The method depends mainly on modelling the mechanical and electrical characteristics of the full rail track system using the simulation tool Simscape, which has been developed by MathWorks. The model is able to provide the track voltage and also the trains voltages. Through the implementation of Energy Storage Systems (ESS) it will be possible to improve the energy efficiency of electric railways by effectively controlling the rail track voltage and the trains contact voltages.
