Computation of Nonlinear Load Harmonic Currents in the Presence of External Distortions

This paper deals with the issues of computation nonlinear load harmonic currents in presence external distortions based on real measurements help passive harmonic. Such values are necessary when modeling an equivalent as current sources distortions. The filter allows to separate and internal distortions, which is determining a single consumer. influence various parameters load, such filter, impedance power supply transformer, consumer, taking into account generation from grid side, consumer considered. It shown that source distortion has practically no effect error estimating magnitudes load. obtained simulation results were confirmed experimentally laboratory test bench. Recommendations for selection have been developed minimize
