Modeliranje verige hidroelektrarn na Soči

JUG, DEAN (avtor), Čepin, Marko (mentor)

Hidroelektrarne so ključni dejavnik pri proizvodnji električne energije in pri zagotavljanju zanesljivosti delovanja elektroenergetskega sistema. Magistrsko delo je razdeljeno na tri dele, ki se med seboj povezujejo in zaključujejo v enovito celoto. V prvem delu so predstavljene delitve hidroelektrarn, opis delovanja hidroelektrarne, predstavitev glavnih delov, ki sestavljajo hidroelektrarno, predstavitev celotne verige hidroelektrarn na reki Soči z njenimi specifičnimi obratovalnimi posebnostmi. V drugem delu je predstavljen model verige. V tem delu je opisano sestavljanje modela, posamezni deli modela, njegove značilnosti in delovanje. V zadnjem delu je predstavljena validacija modela oziroma primerjava med rezultati iz modela in realnimi podatki, pridobljenimi z meritvami na objektu. V analizi delovanja modela, se je primerjalo vse pomembne dele verige, ki vplivajo na točnost delovanja modela. Analiziralo se je kote bazena v akumulacijah, pretoke vode skozi turbine in dvige spodnje vode pri posameznih HE. Primerjava rezultatov med rezultati modela in realnimi vrednostmi je pokazala zadovoljivo delovanje modela. Večjih odstopanj ni bilo opaziti. Napake so se povečevale, ko je voda potovala proti zadnji HE v verigi, vendar so še vedno bile v dopustnih mejah, ki so omogočale pravilno delovanje modela verige.

Izvleček

Hydroelectric power plants are a key factor in the production of electrical energy and ensuring the reliability of the operation of power system. The master's thesis is divided into three parts, which connect each other. The first part presents hydropower plants, a description of the operation of the hydropower plant, the presentation of the main parts of the hydropower plant, the presentation of the entire chain of hydropower plants on the Soča river and its specific operational features. The second part presents the model of the chain of hydropower plants. In this section, we describe how the model is composed, describe the individual parts of the model, its characteristics and operation. The last part presents the validation of the model, the comparison of results from the model and the real data obtained from measurements on the object. In the analysis of the functioning of the model, all relevant parts of the chain were compared, which influence the accuracy of the model's operation. Accumulations, the flows of water through turbines and the rise of the lower water in individual hydropower plant were analysed. Comparison of the results between the results of the model and the real values showed satisfactory operation of the model. No major deviations were observed. The errors increased as the water traveled towards the last of the HPP in the chain, but they were still within the permissible limits that allowed the chain to function properly.
