Abstract EN
The braking process of electric locomotive is featured by short braking time, large braking power, large voltage fluctuations, etc.
Faced with the problem of low utilization of braking energy and high investment cost of the current regenerative braking energy utilization systems, an energy optimization scheme is proposed in this paper by combining the control strategy for energy storage and energy optimization.
The regenerative braking energy utilization system is modeled by analyzing the braking process of electric locomotive.
The instantaneous absorption reference powers of the energy storage subsystem and energy feedback subsystem in braking process are obtained according to the established mathematical model.
The energy storage subsystem uses super capacitor and adopts a power-current dual closed-loop control strategy.
The energy feedback subsystem adopts a voltage-current dual closed-loop control strategy.
Through the tracking control of the instantaneous power, a reasonable distribution of the regenerative braking energy is achieved between the energy feedback subsystem and energy storage subsystem, thereby increasing the utilization efficiency of the two subsystems.
Finally, the performance of the proposed scheme is verified by simulation and experiment.
