Formulación y simulación de flujos de potencia desbalanceados basado en una descomposiciónpor fases

Abstract

In an analysis of power flows, electrical systems are approximated to balanced characteristics, with the operating conditions of the system in a stable state. The approaches made in them reduce the real understanding of the system, which is why the present work has a focus on the existing imbalance in the systems. The present article exposes the elaboration of an open source software for the calculation of the power flows in electrical systems with unbalanced conditions, in the representation of the equipment in phase components, this allows any change to be made in any of the phases of a element that complies with the system and observe which is the affectation that it receives under all these modifications. The software takes as a basis for the development of this work is the Newton-Raphson Rapid Decoupled method, which allows to include the analysis of the generators and their respective voltage regulator. This work demonstrates its validity by means of two electrical systems, which are sometimes different unbalance conditions, to obtain the real operating variables of the system.
