This paper presents an integrated hybrid railway power quality control system (HRPQC) to deal with the power quality problems in the electrical railway supply system. The prominent advantage of HRPQC is that, in the premise of adopting a hybrid compensating scheme for better performance, it can integrate the active system with the main transformer without other expensive low-frequency high-power auxiliary transformers. HRPQC's mathematical model, control idea, and transforming relationship in harmonic frequency are first presented. Second, the harmonic-suppressing mechanism and the resonance characteristics are analyzed in detail. Finally, simulation and experimental results verify the effectiveness of the proposed compensating system.
