Energy-saving Cruising Control Method Developed Based on the Analysis of Energy Consumption Data of Electric Multiple Units

In electric railroads, inverter-controlled vehicles have been used for a long time. In recent years, efficiency of each subsystem of energy-saving traction drive systems has been increased. However, the energy efficiency during operation has not been studied, especially during cruising control. This study developed a method to analyze and reduce powering energy consumption in cruising control based on operation data obtained by an IoT remote monitoring system. The study also showed the achievement of energy saving by performing simulation.
