Abstract:Nesimetrije, ki se pojavijo v elektroenergetskem sistemu, lahko imajo izvor v nesimetričnem odjemu električne energije ali pa v samih elementih prenosnega sistema (transformatorjih, prenosnih vodih ....). Prav pri slednjih so napetostne in tokovne nesimetrije posledica elektromagnetne sklopljenosti med vodnik in sistemi, ki so asimetrično razporejeni v glavah stebrov. Izpeljani izrazi za izračun parametrov voda so bili uporabljeni kot vhodni podatki v modelu dvosistemskega prenosnega voda z enim zaščitnim vodnikom. Model je bil zasnovan v programskem okolju Matlab-Simulink, s katerim so bile opravljene simulacije medsebojnih vplivov in tokovnih nesimetrij. Analiza je bila izvedena za različna obratovalna stanja relativno kratkega voda in v nadaljevanju za vod z vkomponirano transpozicijo vodnikov. V razcepljenem vodu smo poiskali tisto optimalno kombinacijo prepleta faznih vodnikov (transpozicijo), v odvisnosti od razdalje, pri kateri je bila tokovna disimetrija na vhodu vzankanega kraka najmanjša.

Title:MUTUAL INTERRACTION BETWEEN TWO CIRCUITS OF A DOUBLE - CIRCUIT POWER LINE
Abstract:Asymmetries appearing in electromagnetic system originate from asymmetric power consumption or from power transmission elements (transformers, transmission lines etc.). Voltage and current asymmetries in the latter occur due to electromagnetic coupling between conductors and asymmetrically positioned systems in pylon heads. In the diploma thesis derived equations for the calculation of transmission line parameters are used as input data for a model of double circuit power line with one protective conductor. The model is developed in Matlab/Simulink environment in which simulations that consider mutual interactions and current assymetries are performed. Firstly an analysis of various operational statuses of a relatively short power line is conducted. It is followed by the analysis of a power line with transposition of the conductors. In a divided transmission line the optimum relations for transposition of conductors, at which current asymmetry in the wire junction, is minimum, is determined.
Keywords:trasmision line, double circuit line, current asymmetry, wireless power transmission, mutual interaction, electromagnetic coupling, power losses, line transposition
