COMPOUND MATRIX PARTITIONING AND MODIFICATION FOR THE SOLUTION OF BRANCHED AUTOTRANSFORMER TRACTION FEEDS

The increasing use of autotransformer feed schemes in AC electrified r ailways, as a result of their obvious advantages, motivates a detailed analysis of the behaviour of these systems. A novel compound matrix p artitioning and modification method for the solution of a branched aut otransformer feed system is presented. The introduction of branch line s in the autotransformer feed model has stimulated the development of a new solution technique which is very well matched to the problem for mation. Results are cited which indicate that the proposed method can achieve a very efficient and reliable solution.
