Abstract：[Purposes] To address the issues of resonance and harmonic current amplification caused by using a single passive filter for harmonic control in high-speed railway traction networks，and to further improve the effectiveness of harmonic suppression，a collaborative harmonic control scheme combining a passive power filter （PPF） and an active power filter （APF） is proposed.[Methods] Based on practical conditions， starting from the equipment composition of the high-speed railway traction power supply systemto the establishment of a harmonic transmission model for the traction network，this paper briefly explains the complex mechanism of harmonic transmission. Combined with literature analysis，it provides a detailed comparison of the advantages and disadvantages of existing harmonic control strategies for highspeed railway traction networks，thereby supporting the scheme design.[Findings] A model was constructed according to the harmonic characteristics and transmission features of the high-speed railway traction network，and the effectiveness of the hybrid filtering scheme was verified through simulation analysis.[Conclusions] This scheme can effectively suppresssystem resonance while achieving efficient harmonic control in the high-speed railway traction network.
