Based on this, the power of the motor can be obtained by combining the electric braking torque, and the braking intensity can be calculated based on the vehicle speed. The energy management system then derives the optimal electric braking torque based on the braking intensity and sends it to the braking controller.
The resulting available braking energy lies between 4000 and 6000 kWh/day per substation, depending on the train headways. This energy could then be used through a storage system to supply several of the electrical loads of the passenger station, saving energy and reducing the greenhouse effect gases production to the environment.
