A Harmonic Mitigation Strategy for High-Speed Railway Traction Networks

Abstract： [Purposes] Aiming at the harmonic control problem in high-speed railway traction power supply systems，a hybrid harmonic mitigation strategy is proposed to further improve the harmonic suppression performance in high-speed railway traction networks.[Methods] The strategy combines an active power filter （APF）and a passive power filter （PPF），employs an improved detection algorithm to enhance thedynamic compensation performance of the APF，and designs a collaborative filtering system with single-tuned and high-pass branches.The approach is verified through Matlab/Simulink simulations. [Findings] Simulation results show that the system's total harmonic distortion （THD） is significantly reduced by using the hybrid topology strategy，demonstrating the eectiveness of APF-PPF collaborative filtering.[Conclusions] The strategy can reduce the capacity requirement of the APF while achieving precise suppression of specific frequency harmonics.
