Estimation of synchrophasor Using Taylor Fourier Transform

Abstract: This paper proposes a modified version of the syn- chrophasor estimation algorithm which uses the non-orthogonal transform defined as a Taylor-Fourier Transform (TFT) and which is based on a Weighted Least Squares (WLS) approx- imation with respect to a second order of Taylor model. The main objective of the project is to measure the magnitude and phase angle of dynamic electrical signal by using Taylor transform algorithm. In this work, a adapted TF-WLS algorithm for Phasor estimation has been introduced to improve the performances under transient conditions. The algorithm depend on adaptation to detect fast changes and enhance Phasor estimation Index terms-Taylor Fourier Transform (TFT),Weighted Least Squares(WLS), Synchro Phasor
