Abstract
- Kinetička energija riječnih struja slabo je istražena za mogućnost proizvodnje električne energije. Zbog toga ima malo novih prijedloga za iskorištavanje tog oblika energije. Ovdje se prikazuje metoda iskorištavanja hidrokinetičke energije riječne struje koja je nastala kombinacijom tradicionalnog vodnog kola i Darrieus turbine. Vodno kolo koristi se zbog povijesno-turističkog značaja, a Darrieus turbina dodaje se zbog povećanja ukupne snage takvog postrojenja. S obzirom na male dimenzije mikro hidroelektrane tog tipa potrebno je precizno odrediti najpovoljnije lokacije. Za te lokacije najvažniji je podatak o brzini i dubini vodotoka jer snaga pri iskorištavanju hidrokinetičke energije ovisi o trećoj potenciji brzine, a dubina je bitna zbog toga jer se Darrieus turbina uranja u vodu. Stoga se model optimizacije lokacija radi na temelju podataka dobivenih mjerenjem hidroloških karakteristika vodotoka pomoću ADCP (Acoustic Doppler Current Profiler) uređaja.<br />The kinetic energy of river currents is weakly researched for the possibility of production of electrical energy. Thus there are very few new suggestions for the exploitation of this energy form. This paper shows a method of exploiting the hydrokinetic energy of river currents created by combining the traditional water wheel and the Darrieus turbine. The water wheel is used due to its historic and traditional meaning and the Darrieus turbine is added due to the increase of the overall power of such a facility. Considering the small dimensions of a micro hydroenergy power plant of this type it is necessary to precisely determine the most favorable locations. For these locations the most important data are the speed and depth of the water flow because the power in using hydrokinetic energy depends upon the third exponent of speed, and depth is important because the Darrieus turbine is immersed in water. Thus, the model of optimizing locations is done based on the data received by measuring the hydrological characteristics of the watercourse using the ADCP (Acoustic Doppler Current Profiler) device.
