PENIDO, Débora Rosana Ribeiro; ARAUJO, Leandro Ramos de; CARNEIRO JR., Sandoval  and  PEREIRA, José Luiz Rezende. Methodology for analysis of N-Conductor electrical systems using the Current Injection Method. Sba Controle & Automação [online]. 2010, vol.21, n.3, pp.308-321. ISSN 0103-1759.

In this work a new methodology for steady state analysis of n-conductor electrical systems is presented, with the capability to model a variety of components found in electrical power systems. The methodology is shown to be efficient and robust, with general application and it can be used to analyze balanced or unbalanced systems, radial or meshed, of transmission, sub-transmission, distribution or industrial, including large-scale power systems. The proposed methodology was called the N Conductor Current Injection Method - NCIM and is based on the Current Injection Method in rectangular coordinates, formulated directly in phase coordinates and uses the Newton-Raphson method as a solution process.

Keywords : Multi-phase power flow; current injection method; component modeling; unbalanced systems.
