Abstract

Adjustable Speed Drives (ASD) or Variable Frequency Drives (VFD) are well known today for its ability in achieving power efficiency. ASD is commonly used in fans, heat pumps and it is capable to achieve up to 30% of energy efficiency if installed in compressors. Despite the advantages of using ASD, ASD can cause harmonic problems to the source and to other sensitive equipments connected together in the line. In order to study the behavior of Total Harmonic Distortions (THD) produced by the network of ASDs, the network is set up in the laboratory and measurements of harmonic distortions are made under different loading strategies. The ASD is simulated in Matlab/ Simulink. Then, experimental and simulation results are analyzed and compared.
