Optimized Compensation of Unwanted Current Terms by AC Power Converters Under Generic Voltage Conditions
(Ieee-inst Electrical Electronics Engineers Inc, 2016-12-01)
This paper formulates an optimization-based algorithm for the compensation of unwanted current terms by means of distributed electronic power converters, such as active power filters and grid-connected inverters. The ...
Conservative Power Theory, Sequence Components and Accountability in Smart Grids
(Wydawnictwo Sigma-n O T Sp Z O OWarsawPolónia, 2010)
Correction of power transformer no-load losses, measured under nonsinusoidal voltage waveforms
(IEEE, 1989)
A method to calculate the iron losses in power transformers with highly distorted supply voltages is introduced. The appearance of small loops inside the main hysteresis loop is analysed and a method is proposed that takes ...
Behaviour of power-factor meters under non-sinusoidal current and voltage
(Francis and Taylor, 1991)
Different types of analogue and digital power-factor meters used for low frequencies are studied. Their errors are calculated when the current or voltage waveform is distorted. It is shown that large errors appear under ...
Practical comparisons among electronic energy meters, a precision energy meter and IEEE1459 for reactive energy measurements, under unbalanced and non-sinusoidal conditions
(2012-12-01)
This paper presents a practical experimentation for comparing reactive/non-active energy measures, considering three-phase four-wire non-sinusoidal and unbalanced circuits, involving five different commercial electronic ...
Flexible active compensation based on load conformity factors applied to non-sinusoidal and asymmetrical voltage conditions
(2016-02-10)
This study proposes a flexible active power filter (APF) controller operating selectively to satisfy a set of desired load performance indices defined at the source side. The definition of such indices, and of the corresponding ...

Harmonics filtering and detection of disturbances using wavelets
(1999-12-01)
Traditional mathematical tools, like Fourier Analysis, have proven to be efficient when analyzing steady-state distortions; however, the growing utilization of electronically controlled loads and the generation of a new ...
Currents' physical components (CPC): Case studies in three phase systems
(2018-06-25)
In this article the CPC theory was implemented in simulation environment with the intention of discussing its application in different circuits and operating conditions. The analyzed conditions focus on three-phase three-wire ...
Comparative analysis for reactive energy measurement methodologies, under non-sinusoidal conditions in three-phase four-wire circuits
(2011-12-28)
This paper presents some methodologies for reactive energy measurement, considering three modern power theories that are suitable for three-phase four-wire non-sinusoidal and unbalanced circuits. The theories were applied ...
