Fuzzy Logic for Harmonic Distortion Diagnosis in Power Systems

Harmonic distortion in power systems is an old problem which continues to grow in importance due to the proliferation of non-linear loads and of sensitive electronic devices. Thus, the need of standards to limit such distortion is required. Due to the time-varying nature of the distortion more advanced techniques are required to properly quantify their impact. This paper proposes the utilization of fuzzy logic to analyze, compare, and diagnose harmonic distortion indices in a power system
