An advanced teaching method for the analysis of balanced operations of overhead transmission lines has been described in this paper. The proposed educational method combines theoretical, simulation and experimental approaches with the purpose of a higher-level knowledge achievement. Several exercises have been defined and implemented in the teaching process. Some characteristic overhead transmission line steady state regimes, such as Ferranti effect, natural load flow and capacitive overhead transmission line behaviour, have been analysed. The special analysis has been carried out in order to determine the basic characteristics of the switching transients. Software package MATLAB/Simulink has been used for the estimation of system parameters and for the simulation analysis. Different overhead transmission line models have been compared and useful modelling guidelines have been recommended. Experimental calculations have been performed by using a physically scaled system consisting of multiple Pi sections representing 100 km length 400 kV overhead transmission line. The proposed method has been tested within High Voltage Engineering undergraduate course and useful application feedback from students has been obtained.
