Abstract
The proliferation of high-speed railway systems has intensified the demand for superior power quality in electric traction drives. This paper addresses the critical issues of harmonic pollution and electromagnetic interference in the alternating current (AC) transmission systems of high-speed railways by proposing an advanced rectifier control strategy. Through the use of an improved three-phase Pulse Width Modulation (PWM) technology, this paper presents a method to enhance the quality of voltage and current on the grid side, reduce harmonic pollution, and mitigate electromagnetic interference issues. The proposed method integrates a voltage-current dual closed-loop Proportional-Integral (PI) controller with Space Vector PWM (SVPWM) to achieve a stable, high-quality DC output. The system is modeled and validated through simulations in MATLAB/Simulink. It also aims to reduce the harmonic content and output undistorted current following smooth rectification. The results demonstrate a significant reduction in Total Harmonic Distortion (THD) to 0.45% and a power factor approaching unity, confirming the effectiveness of the strategy in enhancing the performance and stability of the electric traction system.
