Abstract

Electrical power quality defines the health of power system which includes voltage and current quality, reliability of power supply and maintaining sinusoidal nature of waveform. Voltage flickers and fluctuations, poor power factor and harmonics are the most common power quality issues in steel producing plants due to Electric Arc Furnace (EAF), electrical drives and welding machines. Non-linear characteristics of EAF are the major sources of power quality issues that mainly include harmonic production and large reactive power variations. In this paper, harmonic analysis is carried out in steel plant. The measured harmonics crosses the permissible IEEE standard limit. Shunt Passive filter is designed in proposed work for reducing harmonics mainly focusing on dominant 5th and 7 th Harmonics. The performance of passive filter with EAF is simulated in MATLAB as well as CYME software. Hardware and software results are also presented in this proposed work.
