Book Description
Abstract : Steady-state performance of various recursive and non-recursive algorithms are tested in this report according to the test signals given in the IEEE Standard C37.118.1-2011. Phase magnitude and phase angle of the power grid signals have been estimated using Discrete Fourier Transform (non-recursive), Discrete Fourier Transform (recursive), Least Square, and Wavelet Transform Algorithms. Frequency estimation is performed using Discrete Fourier Transform, Weighted Least Square, and Zero Crossing methods. These algorithms are evaluated in LabView software and tested by generating test signals in a Simulink model. Furthermore, Total Vector Error (TVE) is calculated using dynamic test signals as per the IEEE Standard C37.118-2011. Performance of different algorithms are analyzed for various cases and the value of TVE is compared with the permissible error limits given in the standard.

Book Description
THE WEIGHTED LEAST SQUARES FIT OF A REAL TONE WITH ARBITRARY AMPLITUDE, FREQUENCY, AND PHASE, TO A GIVEN SET OF REAL DISCRETE DATA, IS REDUCED TO A ONE-DIMENSIONAL MAXIMIZATION O FA FUNCTION OF FREQUENCY ONLY. This function is manipulated into a form that can be efficiently calculated by one FFT of a complex sequence that is related to the available real data and the arbitrary real weight sequence utilized. The decoupling of the complex FFT outputs, to yield the two functions that are necessary to conduct the coarse search in frequency, is accomplished in an extremely simple fashion. A refined interpolation procedure then fits a parabola in the region near the maximum and gives a fine-grained estimate of frequency. An explanation of the apparently anomalous behavior near zero and Nyquist frequencies is given, which shows that in the limit, a constant plus linear trend is being fitted to the discrete data. A program is presented for the complete procedure, including evaluation of the best frequency, amplitude, and phase of the fitted tone. The technique is applicable to short data records, without any approximations, and for arbitrary weight sequences.

Book Description
The book addresses a relevant field of digital processing and measurement of signals in distribution networks. The importance of the covered topic is evidenced by extensive foreign and domestic professional literature, in the form of publications in leading international journals, and numerous professional and scientific books. For the past two decades, the author has published a number of papers both in international journals and at leading world conferences, further verifying the results he has achieved in this field. It should be noted that he is also the holder of several national patents, which were created precisely as a result of working on the problems of processing complex signals of voltage and current. Readers of this book will be the students of master and doctoral studies both in the country and abroad and experts in the field of signal processing. It is a valuable source for future authors of professional and scientific papers, as a basis on which to start when developing completely new techniques for processing complex signals not only in the power system, but also in other fields of engineering and everyday life.
