Résumé

The increasing use in the industry of non-linear loads based on the power electronic elements introduced serious perturbation problems in the electric power distribution grids. One of the parameters of this system is the waveform which must be as close as possible to a sinusoid. Line currents of three-phase and twelve bridge rectifier suffer from high total harmonic distortion of current (THDi). In this paper we makes an analysis and investigation of harmonics currents propagation in real electric power system with one or tow non-linear loads , the first is a three phase full-wave bridge rectifier (P6) and the seconde is a twelve-pulse bridge (P12) installed in deferent nodes 1 and 2 into an existing distribution network (radial type). In our work we present that this THDi is higher than IEEE standards.
