POWER SUPPLY COMPUTATIONS OF ELECTRIC RAILROADS

RASCHETY ELEKTROZNABZHENIIA ELEKTRICHESKIKH ZHELEZNYKH DOROG

On an electrical railroad electrical supply system loads are continually changed as the result of changes of the modes of the trains, the track profile, the train weights, and their distribution on the supply section. The utilization of regenerative braking causes the appearance of negative loads in the traction network and in some cases in the substations as well. As the result of this the resulting loads on the feeder zone and, to a lesser degree, on the substations, are unequal. The greatest inequality of load is observed on suburban sections, caused by partial starting up and by short periods of energy usage by the trains. The article goes on to discuss the feeding regimen and voltage in the traction power supply, the influence of changes in voltage on the operation of the electrical rolling stock on single phase current roads, the influence of voltage on the throughput of the sections, the regulation of voltage, the longitudinal and transverse capacitance compensation, the traction networks, and their AC and Dc parameters: the calculation of instantaneous schemate, unidirectional feeding, junction feeding; methods of calculating electrical supply systems, calculation on the basis of the train traffic timetable, analysis methods; protection of the traction network from short circuit currents, and, finally, technical economic calculations of the electrical supply systems.
