Comparative Analysis of MRT Jakarta Traction System Considering Electric Train Vehicles with Non-Regenerative and Regenerative Braking

The development of electric train vehicles that can perform regenerative braking has an impact on reducing energy consumption in vehicles and traction substations. This paper presents the performance of the Jakarta MRT system with non-regenerative braking vehicles and regenerative braking vehicles. This study aims to determine how much regenerative braking impacts energy consumption. This paper uses the MRT Jakarta Phase 1 Lebak Bulus-Bundaran HI data. A single vehicle is modeled to obtain a single vehicle profile, including speed, power consumption, and energy consumption. The single vehicle profile is configured with headway and dwell time to obtain the catenary drop voltage and traction substation energy consumption. The calculation results show that regenerative vehicles decrease single-vehicle and total traction substation energy consumption, but catenary losses increase. Overall, total traction substation energy consumption decreases by 43.45%.
