The calculation of equivalents of electrical circuits is a circuit analysis strategy of simplification with theoretical importance since the most primary developments of circuits theory up to the more elaborated theories which support fault analysis, power flux analysis, system protection and electromagnetic transients. In this document it is proposed a new methodology, via graph theory, for obtaining equivalent networks to be used on power flow studies with ANAREDE. The graph of the National Interconnected System (SIN), with its four electrical islands is presented alongside the graph of a real equivalent network with 120 buses on the vicinities of Joairam 230/69 kV substation, in Recife-PE.
