Experimental Measurements and Computer Simulations of Home Appliances Loads for Harmonic Studies

Due to the advancement in power electronics industry, home appliances become more power electronics based. The widespread use of these nonlinear loads increases the harmonics in distribution systems and affects the voltage quality of power systems. In order to quantify the harmonics produced by LCD TV, regular refrigerator and Adjustable Speed Drive (ASD) washer precisely, accurate modeling of these loads are required. Firstly, experimental measurements have been carried out to quantify the harmonics injected by the loads. Then, Matlab Simulink is used to model and simulate these loads to give close results to the experimental measurements. Such models help engineers and researchers to evaluate the harmonics that exist within a residential sector.
