Sažetak
The Norton equivalent model for harmonic load modeling is used widely. The parameters of the model are usually calculated analytically. These calculations are based on measured or simulated waveforms of the voltage or current. In this case the harmonic analysis is needed to obtain the harmonic spectra. After this step the model parameter values are calculated for each harmonic separately. The relative phase shifts of all measured harmonic voltages and currents are most important for correct calculation of Norton model parameters. The different estimations in power network are used to determine the phase shifts. The use of the evolutionary algorithm to determine the voltage and current harmonic phase shifts is research in the paper. The proper optimization problem is defined and one of the evolutionary algorithms is used to solve the problem. The method verification will be done by comparison of simulated wave forms obtained by a computer program.
