20.500.12556/DKUM-16790 OPTIMIZACIJA SREDNJENAPETOSTNIH 20 KV DALJNOVODOV Z DIFERENČNO EVOLUCIJO IN METODO KONČNIH ELEMENTOV OPTIMIZATION OF MEDIUM VOLTAGE 20 KV TRANSMISSION LINES WITH DIFFERENTIAL EVOLUTION AND FINITE ELEMENT METHOD V diplomski nalogi je opisan model srednjenapetostnega 20 kV daljnovoda in zgradba ter vrste omenjenih daljnovodov na distribucijskem območju Elektra Maribor d.d. Za sam potek izračunov in modeliranje sta uporabljena programska paketa EleFAnT in MATLAB. Cilj raziskave v diplomskem delu je optimizacija geometrije in postavitve položaja vodnikov v srednjenapetostnem 20 kV daljnovodu. Optimizacijski parametri so posamezne vertikalne in horizontalne razdalje med samimi faznimi vodniki. V današnjem času se optimizacijski problemi rešujejo s tako imenovanih evolucijskim optimizacijskim algoritmom, ki deluje na osnovi biološke evolucije v naravi. V zaključku diplomskega dela so s pomočjo optimizacijskega algoritma Diferenčne evolucije določene vse razdalje med posameznimi faznimi vodniki in stebrom tako, da je jakost električnega polja oz. gostota magnetnega polja pod daljnovodom najmanjša. The following diploma work describes a model of medium voltage 20 kV power line along with the structure and types of previously mentioned power lines in the distribution area of Elektro Maribor d.d. Programme packages EleFAnt and MATLAB were used for calculating and modeling. The goal of the research work is optimization of geometry and placement of position of guides in a medium voltage 20 kV power lines. Optimization parameters are single vertical and horizontal distances between the phase guides. Nowadays optimization difficulties are solved with so called evolutionary optimization algorithm that works on a base of evolution in nature. At the and of this diploma work all of the distances are set between the single phase guides and the power pole, so that the strength of the electrical field or density of magnetic field is the smallest under the power line itself. This was done with the help of an algorithm called differential evolution. srednjenapetostni 20 kV daljnovod električno polje magnetno polje optimizacija diferenčna evolucija metoda končnih elementov medium voltage 20 kV transmission line electric field strength density of magnetic field optimization differential evolution finite elements method true true false [M.
