Harmonic Analysis on an Industrial Plant- a case of petrochemical plant

Recently there are increasingly many loads generating harmonic currents in the industrial plant according to the technology improvement in the power semiconductor devices. This paper presented a result of harmonic analysis study on a petrochemical plant containing many harmonic sources such as rectifiers, UPS, soft starter, and variable speed drives. Alternatives in the quantity of harmonic filters are simulated and compared to keep the harmonic distortion within the limit specified in the IEEE standards.
