ABSTRACT

The emerging development of non - linear loads such as power electronic devices in industry is responsible for injecting harmonics into the electrical network. The static power converters like Variable Frequency Drives (VFD) are mostly used in industries for energy efficiency and process control of an induction motors. This situation cultivates deterioration of voltage and current waveform (i.e.) usually VFD drawn the current from the utility that’s not same as applied sinusoidal voltage waveform. This paper aims to build a simulation model of gas cooling plant to evaluate characteristics of harmonics at different case studies with help of Electrical Transient and Analysis Program (ETAP). Generally, harmonic analyser in ETAP, studies the power network and is subjected to harmonic current injection and harmonic voltage at multiple frequencies and real time network is elucidated from voltage and current harmonic distortion at dominant harmonic frequencies individually. In this project, the harmonic pollution is analysed in ETAP and mitigation techniques are recommended which are that single tuned filters should be installed for worst case condition and simulation results of ETAP shows that harmonic voltage and current are well within the limit value as per IEEE 519 -2014 standard and provides theoretical lookout for the improvement of power quality in the power network.
