Abstract
En una sociedad moderna el suministro fiable y de calidad de energía eléctrica es
imprescindible. Los transformadores son una parte imprescindible para mantener las
cualidades antes mencionadas de dicho suministro por lo que un fallo en estos equipos
puede acarrear consecuencias muy graves.
El presente proyecto está dedicado a crear un programa para el análisis de una
base de datos aportada por la empresa CEIS. El objetivo es analizar dicha base de datos
con dicho programa y así poder detectar fallos en transformadores con más precisión.
Dicha base de datos se ha ido formando a lo largo de los años por multitud de registros
correspondientes al análisis de gases disueltos de una gran variedad de transformadores
El código se ha programado en Matlab. El objetivo del programa no es tanto
extraer conclusiones sobre los transformadores incluidos en la base de datos, como
dotar al usuario de una potente herramienta para analizar una gran cantidad de datos de
una manera sencilla y práctica. Todas las funciones del programa pueden verse en el
apéndice 1.
Entre los diferentes métodos para el análisis de la base de datos se ha optado por
el método Duval por presentar mejores características respecto al resto de métodos. Con
el objetivo de hacer un análisis más profundo de la base de datos se han dividido y
estudiado todos los registros según tres criterios (potencia, tensión y edad).
In a modern society, a reliable and quality supply of electric energy is essential. Transformers are an essential part to keep the qualities of those supplies. For these reasons, a failure in those equipments can bring very serious consequences. This project is dedicated to create a program for analysis of a data base given by the company CEIS. The goal is to analyze this data base with the program; and to be able to detect failures in transformers more precisely. This data base has been made for years with many records from a great transformers variety. The code has been programmed in Matlab. Program’s goal is not to extract transformers conclusions, which are including in the data base; but to give the user a good tool to analyze several pieces of data easily and with less effort. All programs function can be seen in appendix 1. Within the different ways to analyze the data base, the Duval method has been chosen because gives betters results respect to the others. In order to do a deeper analysis, the records of the data base have been divided according three characteristics (power, voltage and age).
