SYMMETRICAL COMPONENTS FOR POWER SYSTEM ANALYSIS

Last but not the least; the author would like to thank his beloved family members, who gave their full support, financial backings and motivation when he needed it most. v ABSTRACT Power flow solutions are needed in both for planning and operation studies. Power flow studi[r]

336 9.1. INTRODUCTION The method of symmetrical components, as developed by Fortescue [1] , has been used to analyze unbalanced operation of symmetrical induction machines since the early 1900s. This technique, which has been presented by numerous authors [2–5] , is described i[r]
