Ajuste de protecciones de un área de subestaciones de
baja tensión de Metro de Madrid

Este documento contiene el ajuste de las protecciones de las líneas de 15 kV (ca) que alimentan las subestaciones de tracción de una área del Metro de Madrid. También contiene el ajuste de las protecciones de las catenarias de 1500 V (cc) que alimentan esa área Metro de Madrid.
Este documento incluye seis secciones. En la sección 4.2 se define al caso de estudio para corriente alterna. La sección 4.3 proporciona el ajuste de las protecciones en 15 kV (ca). En la sección 4.4 se define al caso de estudio para corriente continua. La sección 4.5 detalla el ajuste de las protecciones en 1500 V (cc).

This Master’s Thesis deals with the study of alternating current and direct current protections. Their setting is theoretically studied. The case study and its data are then exposed to present the proposed settings. Finally, the results are compared with actual data.
To make this possible, real data have been collected. The information obtained consists of a unifilar diagram and a protections settings table for each substation in that area. These tables present information about phase and homopolar protections setting parameters.
This document includes protective devices’ settings in 15 kV (ac) lines that feed traction substations in a determinate Metro de Madrid area. It also incorporates protective devices’ settings in 1500 V (dc) catenaries that feed that area.
It contains six sections, highlighting among them section 4.2, which defines the case study of alternating current, section 4.3, which provides protective devices’ settings results in 15 kV (ac), section 4.4, which defines the case study of direct current, and section 4.5, which details protective devices’ setting results in 1500 V (dc).
