New sequence voltage detector for Distributed Generation with high-harmonic distortion using Fourier Linear Combiner

This paper presents a positive negative and zero sequence detector for Distributed Generation with high harmonic distortion. This detector, named Sequence Detector Fourier Linear Combiner (SDFLC) uses a modification of Fourier Linear Combiner and Fortescue Transform to instantaneously estimate the amplitude, phase and frequency of all phase and all components from a three-phase signal. The SDFLC demonstrate a robust and reliable algorithm to detect high harmonic problems. In this paper, its structure was completely presented and tested to a sort of detection problems.
