Abstract
Regenerative braking energy is one of the key technologies of urban rail transit system, but the application brings a large amount of problems, such as energy waste, temperature rising and grid voltage swing. This paper presents an approach to solve the above problems based on three-phase voltage source PWM rectifier, which can achieve energy bi-directional flow. The mathematical model for the rectifier is analyzed in detail. The double-closed-loop control strategy is adopted, namely, the inner current-loop track reference current and the outer voltage-loop keeps the output voltage constant. Finally, the simulation experimental results have proved the correctness and feasibility of regenerative braking energy system.
