MODEL CALCULATING THE INSTANTANEOUS MODE PARAMETER A TRACTION POWER SYSTEM MOVING ELECTRIC LOCOMOTIVES

Abstract

Based on the methods of analysis for calculating the electrical parameters of the mode of the traction power supply systems identified deficiencies related to the readability of the calculation and use of non-sinusoidal currents difficulties in that peculiar modern traction complexes with semiconductor converters. Using the methods of electrical engineering theory developed a model for calculating a continuous instantaneous mode parameters of the traction power supply systems, is different from the calculation methods that have been used previously by the fact that the original data is not averages, and pre-defined instantaneous values of electric current and speed. The model, in contrast to these methods is not large discreteness calculations, which greatly improves the quality of the calculation of the sudden change between the different modes of operation of electric and informative value in the calculation of power quality. The possibility of continuous operation for the entire simulation interval based on the location of the place of electric locomotives that move count distribution of voltage drop, loss of power and non-sinusoidal voltage coefficient for each of the electric contacts in place.
