This overview paper presents and compares different methods traditionally used for
estimating damped sinusoid parameters. Firstly, direct nonlinear least squares fitting the …

We present a single synchrophasor estimation (SE) algorithm that is simultaneously
compliant with both P and M phasor measurement unit (PMU) performance classes. The …

Featured Application Real-time measurement of amplitude, phase, frequency and rate of
change of frequency (ROCOF) of current and voltage AC signals in power transmission and …

In view of the demand for accurate modal identification, and based on the characteristics of
free vibration response, this paper introduces a new window function for Fourier Transform …

This paper describes the discrete Fourier transform (DFT) interpolation algorithm for arbitrary
windows and its application and performance for optimal noncosine Kaiser-Bessel and …

A complex-valued least-squares (CLS) framework is proposed in order to enhance the
accuracy of the smart discrete Fourier transform (SDFT) algorithms for power system …

Several window functions are currently applied to improve the performance of the discrete
Fourier transform (DFT) harmonic detection method. These window functions exhibit poor …

We address here the issue of jointly estimating the angle parameters of a single sinusoid
with Wiener carrier phase noise and observed in additive, white, Gaussian noise (AWGN) …

In this paper, a new method for the simultaneous estimation of power components and
frequency is presented. The method is based on the application of the unscented Kalman …

In this article, the estimation of the frequency of a complex exponential in noise is reviewed.
We examined both the undamped and damped cases and presented robust, accurate, and …
