Research on Model of Rail Potential Distribution and Its Simulation

With the traction current of electric locomotive increasing,the rise of rail potential becomes a considered problem.In this paper,based on the establishment of rail potential distribution model and the simulation used MATLAB,the potential and current distribution on the rail are depicted.The main parameters and other factors affecting the rail potential distribution are also discussed.The train factor was introduced to amend the peak of the rail potential.Finally,the calculated data of the rail potential under normal circumstances is compared with the actual data to verify the correctness of the model.
