Abstract For the purpose of managing power quality of traction power supply system caused by electric locomotives, a railway power static conditioner is discussed in the paper. In order to improve the treatment effect and control performance of power regulator, a novel double-loop control block diagram is constructed. Taking into account the importance of current tracking, a recursive integral based double-hysteresis control method is proposed, which combines the characteristics of two control methods and effectively improves response speed and control accuracy. In order to maintain DC-link voltage to ensure normal operation of regulator, a composite pseudo-PI control method is proposed based on energy balance principle, which can achieve a smooth and stable control for DC-link voltage. Finally, simulation and experimental results confirm the correctness of proposed control method, and it can improve power quality of traction system effectively.

Key words： Power quality railway static power conditioner negative sequence current recursive integral control pseudo-PI control double-hysteresis control
