Abstract
Transformatori su jako bitne komponente elektroenergetskih sustava. Njihova pouzdanost i dugovječnost utječe na stabilnost i učinkovitost cijele elektroenergetske mreže. Stoga je bitno kontinuirano pratiti i procjenjivati stanje transformatora kako bi se osigurala pravovremena intervencija i spriječili kvarovi koji mogu uzrokovati ozbiljne poremećaje i gubitke. Nakon upoznavanja s pojmovima strojnog učenja i obrade podataka naredni cilj je bio metodama strojnog učenja razviti model i aplikaciju koja će predvidjeti stanje transformatora na temelju analiza ulja te predložiti i uputiti u potrebne postupke održavanja. Uspoređeno je nekoliko algoritama za klasifikaciju, a najbolje rezultate je imao Random Forest algoritam koji je potom korišten u izradi aplikacije. Aplikacije je jednostavna za korištenje te upućuje korisnika kako bi trebao postupiti. Aplikacija je realizirana u Streamlit razvojnom okruženju koristeći Python programski jezik.
Abstract (english)
Transformers are very important components of power systems. Their reliability and longevity affect the stability and efficiency of the entire power network. Therefore, it is essential to continuously monitor and assess the condition of transformers to ensure timely intervention and prevent failures that could cause serious disruptions and losses. After familiarizing ourselves with the concepts of machine learning and data processing, the next goal was to develop a model and application using machine learning methods to predict the condition of transformers based on oil analysis and to suggest and guide the necessary maintenance procedures. Several classification algorithms were compared, and the Random Forest algorithm produced the best results, which was then used in the application development. The application is easy to use and guides the user on how to proceed. The application was implemented in the Streamlit development environment using the Python programming language.
