Harmonic current pollution is a one of the major power quality problem in electrical power
systems. In office buildings one of the main harmonic sources is a large numbers of
computer loads. Especially, personal computers apply harmonic distortions to their power
supply systems. In this study, harmonics models of equipments, a MATLAB
®
code and
single-phase Simulink simulation models are developed for office equipments in order to
analysis harmonic activity in neutral conductor.
