Abstract. This paper presents a novel approach based on the use
of adaptive network-based fuzzy inference systems (ANFIS) to estimate electric
and magnetic fields around an overhead power transmission line. There are
many numerical methods for electric and magnetic field estimation in the
surroundings of power transmission line, but it usually takes substantial
execution time, especially when the high accuracy of obtained solutions
is required. An ANFIS used for simulation of this problem was trained using
the results derived from the previous research performed by the authors
of this paper. It is proved that proposed approach ensure satisfactory
accuracy and time efficiency, and can be a very useful alternative for
such investigations.

APROKSIMACIJA ELEKTROMAGNETNOG POLJA U
OKOLINI DALEKOVODA POMOĆU ADAPTIVNOG NEURO-FAZI
SISTEMA
Ovaj rad predstavlja novi pristup baziran na korišćenju ANFIS-a za estimaciju
električnog i magnetnog polja u okolini dalekovoda. Postoje brojne numeričke
metode za estimaciju električnog i magnetnog polja u okolini dalekovoda
ali obično je znatno vreme izračunavanja, posebno kada se zahteva velika
tačnost. ANFIS koji je korišćen za simulaciju ovog problema je obučen
korišćenjem rezultata dobijenih u prethodnim istraživanjima autora ovog
rada. Pokazano je da predloženi metod obezbeđuje zadovoljavajuću tačnost
i vreme izvršenja i da može biti vrlo koristan alternativni metod za
rešavanje razmatranog problema.
