ANALYTICAL EXAMINATION ON MODELS OF RAILWAY ELECTRIFICATION AT 3 KV DC WITH FEEDER AT -3, -6 & -12 KV DC
The ever increasing demand for high transport capacity in the railway sector, understood both as and increase in speed and as traffic density, brings about the need for a study of the problem of the potentiation and amplification of the existing structures. In the case of lines electrified at 3 KV dc, the increase of the potentiality of the system composed of catenary, track and substations, apart from the increase in the number of the lastnamed, mainly consists in the oversizing of the overhead conductors, in the parallel connection at half-distance (only for double track lines) and in the stabilization of the substation voltage amplitude. Outside these possibilities, alternative solutions, based on non-conventional systems, are to be taken into consideration. This memorandum, taking up proposals previously made in other publications, carries out an analytical study on the possibilities of an alternative potentiation system of the lines by means of the application of "transformers into direct current" (DC/TR) installed along the line and fed by means of a feeder at -3, -6, -12 kV dc.
