Economic impact of power quality (PQ) disturbances on industry is increasing day by day with widespread use of power electronics based devices. These disturbances should be detected quickly and accurately. Fourier transform (FT) has become a powerful tool to detect, classify and analyze various types of PQ disturbances in power systems and signal processing. In this paper, the fundamentals of Fourier series and FT with their types and distinctions over other disturbance detection methods are clearly discussed. An extensive literature review of more than 50 research papers on FT is also presented.
Key words: Power quality disturbances, literature review, harmonics, Fourier transform
