Abstract
In this paper, a practical approach to velocity profile optimization for electric multiple unit was presented. The study focuses on a case of fast urban railway, which is a popular mean of transport across Tricity, Poland. Based on observations and measurements, a potential for improvement of energy efficiency by modifying the speed profile was recognized. In order to conduct necessary calculations, simulation model of railway vehicle was developed using Matlab/Simulink software. Accuracy of results provided by the model was proven against values registered during real train run. Various velocity profiles, including constant-speed and coasting were considered, indicating room for improvement of both vehicle drivetrain efficiency and total energy consumption. Next, velocity profile optimization algorithm was proposed, using Matlab Optimization Toolbox. Calculated optimal run was compared with the measured data, showing notable savings in both running time and energy. Applicability of the developed algorithm was discussed, underlining advantages of the presented approach.
