Abstract

Nowadays, harmonic distortion has been known as a significant problem to maintain power quality. Some harmonics in the power signals are dangerous to sensitive equipment and also cause to power loss. Therefore important to detect harmonics and use different harmonic mitigation techniques to get clean or pure signal for safe operation of the connected equipment and minimize power loss. This project is about modeling/simulation and the effect of using 6 pulses and 12 pulse rectifier circuit commonly found in power distribution system. The model was implemented using MATLAB/Sirnulink with the SimPowerSystem Block Set. The 6 pulse rectifier circuit is involving most AC drives because of its low cost and simplest structure. The 12 pulse rectifier circuit is known to be more expensive, but produces the reduced input current harmonics and voltage ripples. The aim of this research is to detect the harmonic by using 6 pulses and 12 pulse rectifier circuit and analyze the harmonic by using Fast Fourier Transform (FFT) method, plot the stylized spectrum of distorted signal in software MA TLAB with power system frequency and calculate the total harmonic distortion that will be useful for solving problems that related to the power quality.
