The Comparison of Three-Phase and Co-Phase Shunt Active Power Filters for Harmonic Elimination in AC Electric Railway Systems

This paper presents the comparison of harmonic elimination in AC electric railway system using two different active power filters, a three-phase shunt active power filter (TP-SAPF) and a co-phase shunt active power filter (CP-SAPF). The indicator for performance evaluation of two shunt active power filters is the total current harmonic distortion (%THDI) on the three-phase and two-phase sides of the AC electric railway system. Simulink/MATLAB program is used to simulate the harmonic elimination in the considered AC electric railway system. The simulation results show that the TP-SAPF can compensate harmonic only the three-phase side of the system. On the other hand, the CP-SAPF can provide good performance to eliminate harmonic on both the three-phase and two-phase sides of the system. Furthermore, the %THDI values of the source currents after compensation are followed by the IEEE std 519-2014.
