Abstract :
In recent years, a number of power harmonics/interharmonics have been produced due to the increasing use of power electronic systems and time-variant non-linear loads in industry. This phenomenon causes a worse power line pollution in power system. However, it is still a big challenge for DFT to analyze or measure interharmonics. Therefore, this paper unveils the dilemma for using DFT tool in modelling Interharmonics. Some critical cases study with implementation results are introduced and discussed for details.
