Efficient Energy Management for Onboard Battery-driven Light Railway Vehicle

초록

With the requirements for reducing emissions and improving energy or fuel economy, railway industries and researchers are focusing on developing battery powered LRT without overhead catenary wires. The battery-driven railway vehicles enable to recover braking energy while operating catenary-free sections. Therefore, a sophisticated energy storage system and appropriate battery-powertrain management are essential for obtaining the highest possible reduction of greenhouse gas emission and energy consumption and at the same time an increase of the vehicle performance. In this research, architecture of power electronic subsystems including onboard battery energy management is described. In addition, the advanced electrical eco-driving architectures to meet the demands for increased electric loads are analyzed and implemented. The requirements of power electronic components and battery management are presented by using a battery-driven LRT model under development. Finally, proposed eco-driving control strategies and performance evaluation with the sophisticated energy management are verified through simulations.
