The aim of the work is to substantiate the optimization of the structure of the DC traction power supply system with variation of train flows and traction loads. Such optimization should be performed after the reformatting of the train schedule and the subsequent impossibility of increasing the energy performance. The methodological basis for the optimization of the existing power supply system of the traction line is the use of a hybrid traction power supply system with an asymmetric arrangement of active generators.entraction power systemtrain schedulespecific poweroptimization of power supply of electric rolling stockКУЕРArticle
