In this paper a low computation effort Taylor-based Weighted Least Squares (TWLS) synchrophasor estimator that takes into account the contribution of the 2nd harmonic is proposed.

Abstract
In this paper a low computation effort Taylor-based Weighted Least Squares (TWLS) synchrophasor estimator that takes into account the contribution of the 2nd harmonic is proposed. That algorithm, called Simplified TWLS-H(2) algorithm, requires the evaluation of only four Discrete-Time Fourier Transforms samples and the related weighting coefficients. The achieved estimation accuracy is compared with that provided by different versions of the TWLS algorithm published in the literature through computer simulations performed under different steady-state and dynamic conditions suggested in the IEEE Standard C37.118.1-2011 for synchrophasor measurements for power systems for the M-class of performance. The comparison is based on the Total Vector Error (TVE), the Frequency Error (FE), and the Rate-of-change-of-Frequency Error (RFE) parameters.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione
