Abstract :
In this paper, a regenerative energy conversion system for subway is proposed. In order to simulate the actual voltage and current fluctuation in subway system, a active simulator, which is based on PWM AC-DC converter, is developed and implemented. Also, the energy storage system is designed using bi-directional DC-DC converter and super capacitors. The theoretical explanation is carried out and the validity of the proposed system is verified by simulation and experimental results.
