Abstract

Hidroelektrarne so trenutno največji proizvajalec obnovljive električne energije na svetu. Njihova največja prednost je, da ne onesnažujejo okolja, ko enkrat obratujejo. Težava pa je njihova umestitev v okolje, zato je treba narediti kar nekaj izračunov in analiz preden se tak objekt lahko začne graditi. Namen tega diplomskega dela je na primeru potencialne hidroelektrarne, ki bi lahko stala na Muri, preučiti proizvodnjo električne energije glede na vrsto in število turbin ter z uravnavanje zgornje in spodnje vode. S takšno analizo dosežemo, da bo elektrarna lahko obratovala pod najbolj optimalnimi pogoji in prispevala k ekonomski upravičenosti njene izgradnje. Analiziral sem, kakšen vpliv imajo ti dejavniki na proizvodnjo EE in poiskal razporeditve delovanja posameznih turbin za potencialno hidroelektrarno na Muri. V ta namen sem uporabil programsko okolje Excel, ki ponuja možnost izračunov proizvodnje električne energije pretočne in pretočno-akumulacijske hidroelektrarne za različne tipe in število turbin, različne padce ter različne velikosti akumulacije. Izračuni so izvedeni na podlagi urnih pretokov med letoma 2018 in 2019. Rezultati kažejo različno proizvodnjo električne energije in povprečne moči glede na izbrane podatke elektrarne in so navedeni v tabelah in grafični obliki. Na podlagi analize rezultatov sem ugotovil, da se iz električnega vidika najbolj splača izgradnja pretočne HE s tremi agregati s Kaplanovo turbino. Z večjim številom turbin bi lahko še pridobili na zmožnosti regulacije pretoka skozi turbine, vendar je bil izračun zasnovan za analizo maksimalno treh turbin.

Secondary title: Analysis of potential hydro power plant on river Mura
Secondary abstract: Hydropower plants are currently the largest producers of renewable electrical energy in the world. Their greatest advantage is that they do not pollute the environment once they are operational. However, the challenge lies in their integration into the environment, which necessitates various calculations and analyses before such a facility can commence construction. The purpose of this dissertation is to examine, using the example of a potential hydropower plant that could be situated on the Mura River, the production of electrical energy based on the type and number of turbines, as well as the regulation of upper and lower water levels. Through such an analysis, the aim is to ensure that the power plant can operate under the most optimal conditions and contribute to the economic justification of its construction. I analysed the impact of these factors on electrical energy production and determined operational schedules for individual turbines for the potential hydropower plant on the Mura River. For this purpose, I utilized the Excel software environment, which offers the capability to compute the production of electrical energy for both run-of-the-river and run-of-the-river with storage hydropower plants with various types and numbers of turbines, different drops in water levels, and diverse reservoir sizes. The calculations are based on hourly flow rates between the years 2018 and 2019. The results indicate diverse electrical energy production and average power output depending on the selected power plant parameters, presented in tables and graphical representations. Based on the analysis of the results, I concluded that from an electrical perspective, constructing a run-of-the-river hydropower plant with 3 units equipped with Kaplan turbines is the most financially viable option. With a greater number of turbines, additional benefits in flow regulation through the turbines could be obtained, although the calculations were designed to analyse a maximum of three turbines.
