Harmonic pollution survey and simulation of passive filter using MATLAB

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 for domestic loads in power distribution network. The specific case study has been conducted at C K Pithawalla college of Engineering and Technology, Surat, Gujarat. It includes non-linear loads such as-personal computer, LCD, laptop, etc. Harmonic measurement was conducted for individual loads. The selected domestic load 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.
