Reactive power and harmonic distortion control in electric traction systems

Abstract

Electric traction systems generate various power quality problems that have an important impact on its distribution network. In this paper a DC electric traction system was modeled in order to generate the problems that its operation implicated. Once the power quality phenomena were replicated a compensation device, SVC, was added to de distribution network to improve voltage and also a filter was installed in the same node to reduce wave distortion. Finally the possible events that can appear if the original configuration of the compensator device is changed are evaluated.
