Calculation algorithm and method for optimizing electricity consumption for the railway traction system

Abstract

Abstract This article presents a calculation algorithm for establishing the electricity demand consumed by the railway electric traction system on a railway section, as well as methods for lowering power consumption and cost. In order to conceive the calculation algorithm, the following variables are taken into account: the number of trains in circulation on the section, the slope of the section, the train speed and the speed restrictions. For factors that substantially increase electricity consumption, but can be controlled, optimal values are computed using specific equations in the MATLAB program. The optimal values are implemented using the train’s timetable or a railway control system (SCADA). A decrease in power consumption of 5% can be expected with this method.
