Assessment of hydroelectric power potential of Vogršček reservoir |
Sekundarni povzetek: |
In this thesis we discussed the accumulation Vogršček. The main purpose was to assess the energy potential of the accumulation Vogršček taking into account the actual use of water for irrigation. In the first part we described the dam. In the second part we reviewed the hydrological data and other project documentation available about the accumulation. Then we calculated the water balance of the accumulation. We took into account all losses, biological minimum and need for irrigation. In the third part we calculated the energy production for the variant, in which we took into account the hypotheses that in the first year
accumulation only fills up and that the water level in the reservoir should at all times be above the minimum operating water level. The last hypothesis says that the accumulation is full at normal operating water level. In the fourth part we calculated energy production for the
second variant - optimized system, which considered the same first two hypotheses as did the third part. In this part we also took into account that the water level of the accumulation at end of March every year has to be at least at normal operating water level and that the reservoir is full at maximum water level. In both variants, we performed the calculation for several different scenarios, so that we gradually increased the installed power flow and tried to figure out when the production of energy is at its maximum. In the last part, we designed all the technical parameters of the powerhouse, sketched a design and calculated the cost of the investment that would be required to build such power plant. The objective was to determine whether the investment in the construction of the power plant was justified and provide a comparison with the original study of energy use done by the IBE. |

V diplomski nalogi smo obravnavali akumulacijo Vogršček. Glavni namen je bila ocena energetskega potenciala akumulacije Vogršček z upoštevanjem dejanske rabe vode za
namakanje. V prvem delu smo opisali pregrado in akumulacijo Vogršček. V drugem delu smo najprej pregledali hidrološke podatke in ostalo dostopno projektno dokumentacijo o akumulaciji Vogšček. Nato smo izračunali vodno bilanco akumulacije. Pri tem smo upoštevali vse izgube, biološki minimum in potrebe po namakanju. V tretjem delu smo izračunali energetsko proizvodnjo za varianto, kjer upoštevamo predpostavke, da se akumulacija prvo leto le polni in, da mora biti višina vode v akumulaciji ves čas nad minimalno obratovalno gladino ter še zadnjo predpostavko, ki pravi, da je akumulacija polna pri normalni obratovalni koti. V četrtem delu smo energetsko proizvodnjo izračunali za drugo varianto - optimiziran
sistem, kjer smo upoštevali enaki prvi dve predpostavki kot v tretjem delu ter še predpostavki, da mora biti akumulacija konec marca tekočega leta vsaj na višini normalne obratovalne kote ter, da je akumulacija polna, ko izkoristimo tudi visokovodni volumen, torej pri maksimalni koti obratovanja. Pri obeh variantah smo izračun izvedli za več različnih scenarijev tako, da smo postopoma povečevali instaliran pretok elektrarne ter poskušali ugotoviti, pri katerem imamo optimalno proizvodnjo. V zadnjem delu smo zasnovali še vse tehnične parametre in izrisali načrt strojnice ter izračunali strošek investicije, ki bi bila
potrebna za uresničitev take mHE. Cilj je bil ugotoviti ali je investicija v izgradnjo mHE Vogršček utemeljena in podati primerjavo s prvotno študijo energetske rabe, ki jo je naredil IBE. |
