Abstract: The virtual impedance technology is introduced to compensate the harmonics to reduce the harmonic distortion of the supply voltage, so as to improve the quality of supply voltage. This paper analyzes the influence of the harmonics generated by locomotive on the supply voltage, and the principle of virtual impedance technology to compensate the harmonics. Each harmonic component is decomposed from the output current of traction substation by the band-pass filter, and the virtual impedance is introduced into the control circuit to offset the equivalent impedance at the output of the traction substation, so as to reduce the harmonic distortion of the supply voltage. The scheme does not need to add additional compensation equipment, but needs to modify the control strategy to improve the quality of supply voltage.The control strategy is designed, and simulation based on MATLAB/Simulink is conducted. The results show that the proposed scheme can

significantly reduce the harmonic distortion of the supply voltage of the ac-dc-ac traction substation.

Key words: AC-DC-AC traction substation; power quality; multiple quasi proportional resonance(M-Q-PR) controller; virtual impedance;harmonic compensation
