Abstract
In this paper a comprehensive review of electrified railway systems is carried out, identifying the electric power quality deterioration which may appear due to nonlinear dynamic traction loads. Following this topic, a computational simulation of Static Synchronous Compensator
Highlights
Rail transport is seen as the safest and more economical land transportation mode
In order to analyse the performance of STATCOM or Rail Power Conditioner (RPC) to compensate the power quality (PQ) problems in the electrified railway system, a preliminary study of the railway system powered by the V/V or Scott power transformers was carried out
It can be seen that the STATCOM needs to synthesize a much smaller compensation current when the railway system is powered by a Scott power transformer
Summary
Rail transport is seen as the safest and more economical land transportation mode. In addition, it is recognized as one of the main catalysts for the economic growth of nations [1]–[3]. Considering the aforementioned information, it is expected that when an electric locomotive is connected to the catenary, different power quality phenomena arise, namely: three-phase current unbalance, harmonics, low power factor, and other transient phenomena. Despite the need for reactive power to the traction system, in the case of an inductive load, its value must be reduced to avoid higher transmission energy losses This ambiguity can be mitigated by the addition of active power conditioners capable of locally produce the required (b). A comparative analysis of the two systems is presented; section 5 summarizes the main conclusion of this work
