Propagation of higher harmonics of voltage and current in the power system at changing location of nonlinear load

The paper presents the results of the analysis of voltage and current distortions of the power system containing nonlinear load at changing location. The calculations are done for the power system consisted of overhead line 110kV, transformer station 110/15kV, overhead line 15kV and transformer station 15/0.4kV. Simulations were performed in the Microcap environment.
