On the Use of the p-q Theory for Harmonic Current Cancellation with Shunt Active Filters

open access: yesAdvances in Electrical and Electronic Engineering, 2019
Discussion and mathematical proof on necessary and sufficient conditions for the application of the {p-q} theory for compensating the harmonic currents consumed by non-linear load using a shunt active filter are presented.

Compensation of active filter using p-q theory in photovoltaic systems

open access: yesMemories - Materials, Devices, Circuits and Systems
This work proposes an active shunt filter design for grid-connected solar systems, utilizing the p-q instantaneous power theory technique to minimize grid harmonics and reduce reactive power. As a result, the total harmonic distortion (THD) is decreased,

A Review of Control Technique Applied in Shunt Active Power Filter (SAPF) [PDF]

open access: yesEngineering and Technology Journal, 2022
In recent years, electronic transformers and electronic devices (nonlinear loads) have increased. These loads are the source of harmonics (non-sinusoidal and distorted waves) and the interactive force that affects the performance of the power system ...

How to overcome the limitations of p-q Theory: Geometric Algebra Power Theory to the rescue [PDF]

open access: yes2020 IEEE PES Innovative Smart Grid Technologies Europe (ISGT-Europe), 2020
This paper investigates the recent advances in Geometric Algebra-based power theory (GAPoT) and how this tool provides new insights to solve the flaws of one of the most widespread theory in the time domain, the Instantaneous Reactive Power theory (IRP) and its further enhancements. GAPoT can be applied to single-phase and multi-phase systems to obtain

open access: yesInternational Journal of Group Theory, 2022
‎For a finite group $G$‎, ‎three of the positive integers governing its‎ ‎representation theory over $\mathbb{C}$ and over $\mathbb{Q}$ are‎ ‎$p(G),q(G),c(G)$‎.

Quantum theories of (p, q)-forms [PDF]

open access: yesJournal of High Energy Physics, 2012
We describe quantum theories for massless (p,q)-forms living on Kaehler spaces. In particular we consider four different types of quantum theories: two types involve gauge symmetries and two types are simpler theories without gauge invariances. The latter can be seen as building blocks of the former.

Harmonics Analysis of Input Current of 3-Phase PWM Rectifier

open access: yesAndalas Journal of Electrical and Electronic Engineering Technology, 2021
Rectifier is a non-linier load that causes harmonic distortion in the power system. Pulse-width modulation (PWM) method is an effective method in pressing the magnitude of harmonics in a rectifier application,  it provides an almost sinusoidal input ...

p-q Theory power components calculations [PDF]

open access: yes2003 IEEE International Symposium on Industrial Electronics ( Cat. No.03TH8692), 2004
The "generalized theory of the instantaneous reactive power in three-phase circuits", proposed by Akagi et al., and also known as the p-q theory, is an interesting tool to apply to the control of active power filters, or even to analyze three-phase power system in order to detect problems related to harmonics, reactive power and unbalance.

THE DEFINABLE (P, Q)-THEOREM FOR DISTAL THEORIES [PDF]

open access: yesThe Journal of Symbolic Logic, 2017
AbstractAnswering a special case of a question of Chernikov and Simon, we show that any non-dividing formula over a model M in a distal NIP theory is a member of a consistent definable family, definable over M.
