Abstract : Power quality has become prime criteria in modern scenario of power system analysis. Today, non-linear loads make up a large percentage of all electrical demand. Non-linear loads draw current in short pulses during the peak of the line voltage. These non-sinusoidal current pulses introduce unanticipated reflective currents back into the power distribution system and these currents operate at frequencies other than the fundamental frequency. This investigation is mainly based on the issues relating to the power quality of induction furnace, as it is considered as one of the major non-linear loads among industries. Power quality analyzer is used at the installation of induction furnace to observe the harmonics generated by the electrical appliances. The Simulink model of induction furnace is developed in MATLAB based on the related schematic and wiring diagram of the installation. The possible implementation of passive filters is exhibited to reduce harmonics with the Simulink model of induction furnace. Wavelet transform technique is also implemented to mitigate the harmonics.
