Abstract


The article discusses the possibility of providing the required accuracy in modeling real traction network environment MatLab. Analyzed the influence of the number of cells in the block diagram of traction network on the accuracy of calculation of voltage drops, which are the criteria for the evaluation of the simulation model. By using these schemes and the corresponding instantaneous calculations achieved acceptable accuracy for engineering calculations. It should also be noted that the pattern of electric railway is of importance not only the amount of load, but their arrangement, namely, the error caused by inaccurate placement of the instantaneous load. In places with a matching coordinate EPS cell boundaries such error does not occur.
