Análisis de Factibilidad de la reconfiguración del sistema de subtransmisión de la E.E.R.C.S. C.A. por la Inserción de nuevas subestaciones y cambio de nivel de voltaje

Abstract

The present work focuses on the optimization of subtransmision system the E.E.R.C.S. C.A., through line optimal switching to improve losses, voltage profiles and reduce short-circuit currents; this by implementing a programming routine developed in Phyton language that uses Digsilent Power Factory software (specialized software for network analysis), this routine performs an exhaustive search and determines the optimal configuration of the system; the parameter will be switching from 1 to 5 lines at a time. As a first part, is done the analysis of the current subtransmision system the E.E.R.C.S. C.A., determining the parameters that have to be improved; for this, the MATPOWER tool (mathematical analysis software) is used, which is a free the MATLAB package; finally, a comparison is made between the two software’s used. The second part of the study analyzes how the system behaves with the insertion of a generation substation using MATPOWER and the insertion of a reduction substation for distribution using Digsilent Power Factory. As a third part, the optimization of the system in the current state is carried out and a configuration is proposed with the insertion of a reduction substation for distribution, using the exhaustive search routine for optimal line commutation. Finally, an analysis of the change the voltage level from 69 kV to 138 kV in a specific line is presented, which presents parameters to improve, whit this intended to verify the feasibility of this change, determining the configuration so that the system works in optimal conditions.
