Analiza proizvodnje električne energije v mali hidroelektrarni

HRAST, MATIJA (author), Čepin, Marko (mentor)

Analiza proizvodnje električne energije je eden od temeljnih kriterijev pri odločitvi ekonomske upravičenosti izgradnje male hidroelektrarne. Da opravimo analizo proizvodnje električne energije, je potrebno poznati malo hidroelektrarno kot celoto. Namen diplomskega dela je na primeru izbrane male hidroelektrarne preučiti hidrologijo in posledično proizvodnjo električne energije. Tako je nastalo diplomsko delo, ki je razdeljeno v tri ključne dele. V prvem delu so predstavljene delitve malih hidroelektrarn glede na moč, padec in vrsto dotoka ter je izpeljana enačba moči hidroelektrarne, ki je osnova za izračune letne proizvodnje električne energije. V drugem delu so opisani sestavni deli male hidroelektrarne s poudarkom na tipih turbin: Francis, Kaplan in Pelton ter njihovi izkoristki v odvisnosti od pretoka. V tretjem delu so predstavljene osnovne karakteristike izbrane male hidroelektrarne Kneža. Analizirani so hidrološki podatki za podan vodotok. Na osnovi predstavljenih podatkov smo v računalniškem programu izračunali in z grafi primerjali letno proizvodnjo električne energije za primere, da bi v elektrarni obratovale Francisova, Kaplanova in Peltonova turbina izbrane nazivne moči. Rezultati kažejo različne količine proizvodnje električne energije v izbranih primerih. Identificirana je varianta, pri kateri je količina proizvedene električne energije največja.

• Title: Analysis of electric energy production in a small hydro power plant

Abstract

The analysis of electrical energy production is one of the basic criteria for determining the economic viability of constructing a small hydropower plant. In order to analyse the electrical energy production, it is necessary to know the hydroelectric power plant as a whole. The purpose of the diploma thesis is to study the hydrology and consequently the electricity production on the case of the selected small hydroelectric power plant. The result of this is the diploma thesis, which is divided into three main parts. The first part presents the types of small hydropower plants, divided by power, head range and different site layouts. A hydroelectric power equation of hydropower plant is derived, which is the basis for the analysis of electrical energy production. The second part describes the components of a small hydropower plant with an emphasis on the turbine types: Francis, Kaplan and Pelton and their efficiencies, which depend on the flow. The third part presents the basic characteristics of the selected small hydropower plant Kneža. The hydrological data for a given river flow are analysed. On the basis of the presented data the annual electricity production was calculated in a computer program and a comparison was made between the graphs exemplifying the Francis, Kaplan and Pelton turbines working at the rated power. The results show different amounts of electric energy production in the selected cases. A variant is identified where the amount of electric energy produced is the greatest.
