Small hydropower plant project

U radu je prikazana mogućnost izgradnje male hidroelektrane na rijeci Gackoj u Ličko-senjskoj županiji. Područje spada u ekološki značajno područje stoga podliježe posebnim propisima kojih se mora pridržavati. Analiziran je protok rijeke i raspoloživi pad, odabrana lokacija planiranog zahvata hidroelektrane te izrađeno tehničko rješenje. Iz prikupljenih podataka protoka višegodišnjeg razdoblja napravljena je statistička analiza i izvršena usporedba krivulje trajanja protoka prema dvije metode, Gaussova i Log Pearson III distribucija koja je odabrana kao mjerodavna. Na temelju instaliranog protoka odabrana je vrsta turbine i snaga generatora, izračunati investicijski troškovi hidroelektrane, prihodi od prodaje, prikazan je rok povrata investicije odnosno ekonomska opravdanost izgradnje, dok je u konačnici rada dan shematski prikaz turbine i strojarnice te tlocrt male hidroelektrane.The scope of the thesis is to present the possibility of building a small hydropower plant on the Gacka River in Lika-Senj County. The area belongs to an ecologically significant area, therefore it is subject to special regulations that must be followed. The flow of the river and the available net head were analyzed, the location of the planned hydropower plant was selected and a technical solution was developed. A statistical analysis was made from the collected flow data of a multi-year period and a comparison of the flow duration curve was made according to two methods, Gaussian and Log Pearson III distribution, which was chosen as the authoritative one. Based on the installed flow, the type of turbine and the power of the generator were selected, the investment costs of the hydropower plant, sales revenues were calculated, the investment payback period, i.e. the economic justification of the construction, was presented, and at the end of the work, a schematic representation of the turbine and powerhouse and the floor plan of the small hydropower plant was given
