Orodje za analizo rezultatov sistema SUMO pri topologiji N-1

Bogataj, Oskar (author), Blažič, Boštjan (mentor)

Podjetje Eles v sklopu projekta SUMO (Sistem za ugotavljanje mej obratovanja) razvija sistem za napovedovanje maksimalne dovoljene tokovne obremenjenosti nadzemnih vodov in transformatorjev, in sicer s pomočjo podatkov vremenskih modelov in merjenih atmosferskih spremenljivk ter trenutnih in napovedanih obremenitev elementov omrežja. Diplomska naloga opisuje izdelavo programskega orodja, ki analizira rezultate SUMO pri topologiji N-1. Orodje z uporabo vrtilnih tabel programa Microsoft Excel omogoča hitro analizo rezultatov sistema SUMO. Uvoz podatkov je omogočen preko poizvedb iz podatkovne baze PostgreSQL. Za razumevanje delovanja orodja je treba poznati tako številne elemente, ki sestavljajo orodje, kot tudi ozadje projekta SUMO. V diplomski nalogi najprej predstavim obremenitve nadzemnih vodov, projekt SUMO in posamezna orodja, ki sem jih uporabil za izdelavo tega orodja. Sledi opis izdelave zadnje različice orodja. Opis postopka izdelave je razdeljen na več faz, ki opisujejo izdelavo posameznih elementov orodja in razlagajo vlogo členov v orodju. V zadnjem delu prikažem način uporabe orodja in testiranje zmogljivosti orodja. Pri načinu uporabe sta prikazana izpis in filtriranje podatkov. Pri testiranju pa je prikazan napredek v hitrosti orodja in njegovi zanesljivosti v primerjavi s prvo različico orodja.

Abstract

As part of the SUMO project, the company Eles is developing a system that predicts the variable maximum permissible current load of power lines and transformers, using weather model data and measured atmospheric variables, as well as current and predicted loads of network elements. This thesis describes the development of a tool that analyzes SUMO results for N-1 topology. The tool enables a quick analysis of SUMO system results in the Microsoft Excel pivot tables and the data is being imported through queries from a PostgreSQL database. To understand how the tool functions we first need to know both the many parts that make up the tool as well as the background for the SUMO project. Therefore, in this thesis, I first present the loads of power lines, the SUMO project, and the individual tools I used to develop this tool. The following is a description of development of the latest version of the tool. The description of the development is divided into phases describing the construction of individual tool elements and explaining the role of the element in the tool. The last section shows how to use the tool (namely data display and data filtering) and also the testing of the tool, where progress in speed and reliability is shown compared to the first version of the tool.
