Coordinación de protecciones y análisis de fallas en circuitos de distribución, caso del circuito Y410

Protection coordination and fault analysis in distribution circuits, case study of circuit Y410

Abstract

The Y410 circuit of the distribution network of the municipality of Camagüey has a large extension, its layout is rural, and it has a high number of interruptions. In the initial section there are important clients such as Frigorífico and IPVCE. Since the greatest number of effects do not occur in this initial part, it was proposed to study this circuit with the objective of moving the Nulec Y230 from its position to the position of the disconnector C214. In addition, the possibility of synchronizing the PSFV ¨Antonio Pías Gómez I¨ and the PSFV ¨Antonio Pías Gómez II¨ of 2.5 MWp each to this circuit was studied. The circuit was modeled, carrying out the flow of loads, the study of short circuit levels and the coordination of electrical protections. The results of the study allowed the connection of the photovoltaic systems, but not the movement of the Nulec Y230 to the position of the C214.
