Abstract This paper proposes a harmonic impedance measuring apparatus based on single phase cascaded H-bridge converters. The apparatus adopts the hierarchical control strategy to inject harmonic currents into traction power supply systems (TPSSs) with controllable frequencies and amplitudes. Power flow relationship between TPSSs and the apparatus is established. Working principle of the apparatus is clarified. The proposed control strategy is composed of three levels. The top power control level is employed to absorb active power and compensate the loss of this apparatus. The second harmonic control level is utilized to generate harmonic currents. The third voltage balancing control level is applied to balance the capacitor voltage of H-bridge converters. Theoretical analysis and simulations about the performance of this apparatus are carried out. Experiment results in laboratory scale confirmed that the apparatus can measure system harmonic impedance precisely.

Key words： High-order resonance traction power supply system harmonic impedance cascaded H-bridge hierarchical control
