Simulation Research on Energy Saving Scheme of Metro Vehicle Regenerative Braking

In the primary period, only resistance braking and mechanical braking are adopted by metro vehicles. It will bring the temperature and energy loss increasing and is not good for energy saving. With the simulation data and under the different working diagrams of vehicle, we calculate and analyze changes of saving energy with regenerative braking or with resistance braking. Results show that regenerative braking is more economical.
