Effects of harmonic distortion on the active and reactive power measurements in the time domain: A single phase system
(
IEEE Computer Society
, 2001 , Conference Paper)
A new application of the least error squares (LES) estimation algorithm is given for identifying, in the time domain, the active and reactive power from available samples of voltage and current waveforms. The digital ...
Frequency and harmonics evaluation in power networks using fuzzy regression technique
(
IEEE Computer Society
, 2001 , Conference Paper)
A new technique for frequency and harmonic evaluation in power networks is proposed in this paper. This technique is based on fuzzy linear regression and uses the digitized voltage samples, which are fuzzy numbers, to ...
Harmonic modeling of linear and nonlinear loads based on Kalman filtering algorithm
(
Elsevier
, 2004 , Article)
Most harmonic nonlinear load modeling techniques developed in the last two decades, assume that the load connected to the load bus has a constant admittance, inductive or capacitive, which depends on the mode of operation ...
Fuzzy linear parameter estimation algorithms: A new formulation
(
Elsevier
, 2002 , Article)
In this paper, we present a new formulation of a fuzzy linear estimation problem as one of the linear programming where the objective is to minimize the spread of the data points, subject to constraints on each measurement ...

, 2003 , Article)
A new technique for frequency and harmonic evaluation in power networks is proposed in this paper. This technique is based on fuzzy linear regression and uses the digitized voltage samples, which are fuzzy numbers, to ...
A new digital transformation for harmonics and DC offset removal for the distance fault locator algorithm
(
Elsevier
, 2004 , Article)
This paper presents a new application of Park's transformations to identifying the positive sequence of the fundamental components of the three-phase voltage or current signals needed for fault locator algorithm. The problem ...
Identification of individual types of harmonic loads in an electric power system-bus
(
Elsevier
, 2004 , Article)
Some buses in a power system feed power to loads that are sources of harmonics. This type of bus is called a complex-bus. This paper provides a new application of the constrained least absolute value algorithm (LAV) to ...
Park's transformation application for power system harmonics identification and measurements
(
Taylor & Francis
, 2003 , Article)
This paper presents the application of Park's transformation for identifying and measuring power system harmonics. One of the advantages of the proposed technique is that it does not need a model for the harmonics components ...
