The AC 2Ã25 kV power supply system is a widespread solution in high-speed railway networks. Owing to the operation of high-power trains in these systems, the 4Q converter generates a high amount and wide spectrum of harmonic currents, which may interface with the signaling systems, communication devices and utility power systems. In this paper, a new Active Railway Power Quality Compensator (ARPQC) based on two-phase, three-wire converter is proposed to suppress harmonics and improve the displacement factor of the system. In order to have an accurate analysis, a suitable model of 4Q converter and eight-conductor based Overhead Catenary System (OCS) together with autotransformers have been developed. The precise simulation results have been provided to verify the effectiveness of the proposed compensator.

Abstract
The AC 2Ã25 kV power supply system is a widespread solution in high-speed railway networks. Owing to the operation of high-power trains in these systems, the 4Q converter generates a high amount and wide spectrum of harmonic currents, which may interface with the signaling systems, communication devices and utility power systems. In this paper, a new Active Railway Power Quality Compensator (ARPQC) based on two-phase, three-wire converter is proposed to suppress harmonics and improve the displacement factor of the system. In order to have an accurate analysis, a suitable model of 4Q converter and eight-conductor based Overhead Catenary System (OCS) together with autotransformers have been developed. The precise simulation results have been provided to verify the effectiveness of the proposed compensator.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
