Abstract

Abstract--Power quality is becoming a major concern of
today’s power system engineers. Harmonics play an important
and major roll in deteriorating power quality, called harmonic
distortion. Harmonic distortion is measured in terms of THD
(Total Harmonic Distortion). This paper presents harmonic
field measurement in power distribution network. The specific
case study has been conducted at C K Pithawalla college of
Engineering and Technology, Surat, Gujarat. It includes nonlinear
loads such as-personal computer, LCD, laptop, etc.
Harmonic measurement was conducted for individual loads.
The selected distribution network is simulated using MATLAB
software. Simulation and design of passive filter is presented in
METLAB for harmonic mitigation. Results of the same are
analyzed taking in to account IEEE standards limits for
harmonic distortion.
