Identification Of Harmonic Source For Electric Arc Furnace Load Using Fast-Fourier Transform

Harmonic pollution has become a major problem in electrical power networks which can cause problems like the reduction load’s lifetime, failure of protection devices to operate efficiently, instabilities of power system interference in operating systems and all these can contribute to economic losses and downtime. Therefore, harmonic source identification is one of the major problems. Proper identification of the harmonics source is an essential for developing penalty based schemes for harmonic generation and for the design of mitigation equipment to reduce harmonic. This dissertation aims to identify and analyze the harmonics source in power system using Fast-Fourier Transform (FFT) with effective cost efficiencies using single-point measurement approach. The sources of harmonic that been focused in this study is Electric Arc Furnace and finally, the applicability of the modelling system is tested with another harmonic source, Rectifier. The signification finding of this research shows the harmonic sources location can be identified by referring to the relationship between fundamental impedanc
