power factor
Opis:: This brief communication addresses the case of a dc nonlinear load supplied with a perfectly constant instantaneous power. A careful analysis shows that this condition does not provide optimum transfer of electric energy .

Tytuł:: A Poynting Vector Approach to the Study of Power Flow through a Transformer
Autorzy:: Todeschini, G.
Emanuel, A. E.
Powiązania:: https://bibliotekanauki.pl/articles/262661.pdf
Data publikacji:: 2007

Tematy:: power definitions

Poynting vector
harmonics
Opis:: This work deals with the flow of the electromagnetic energy through an idealized single-phase transformer supplied with nonsinusoidal voltage and supplying a nonlinear load. The electromagnetic flux components of the energy that flows from primary to secondary as well as the flux of energy stored in and ejected from the dielectric space surrounding the windings are identified and quantified. The electromagnetic flux components are correlated to well known instantaneous powers. These powers are not clever mathematic expedients but correct expressions that mirror the actual physical phenomena and lead to a more realistic interpretation of apparent power and its resolution.

Tytuł:: Comments on "Physical Interpretation of the Reactive Power in Terms of CPC Power Theory Revisited"
Autorzy:: Czarnecki, L. S.
Haley, P. M.
Powiązania:: https://bibliotekanauki.pl/articles/262839.pdf
Data publikacji:: 2013
Wydawca:: Akademia Górniczo-Hutnicza im. Stanisława Staszica w Krakowie
Tematy:: power definitions
scattered power

harmonic generated power
finite energy signals
Opis:: The paper evaluates the possibility of formulating the Currents’ Physical Component (CPC) – based power theory in the time-domain. It was concluded that the currents’ physical components, defined originally in the frequency-domain, can be calculated in the time-domain, but there is still the lack of their physical interpretation in that domain.

Tytuł:: Currents physical components (CPC) in circuits with nonsinusoidal voltages and currents. Part 1, Single-phase linear circuits
Autorzy:: Czarnecki, L. S.
Powiązania:: https://bibliotekanauki.pl/articles/262747.pdf
Data publikacji:: 2005
Wydawca:: Akademia Górniczo-Hutnicza im. Stanisława Staszica w Krakowie
Tematy:: nonsinusoidal voltages and currents

unbalanced currents or powers
Opis:: The paper summarizes the present state of discussions on power phenomena, power definitions and compensation in single-phase linear circuits. The main concepts developed over several decades on how various non-active powers in circuits with nonsinusoidal voltages and currents should be defined and compensated are presented along with a detailed discussion of these concepts. The paper presents also the concept of the single-phase load current decomposition into Currents' Physical Components (CPC) and its application for power definitions and compensation in such circuits. The paper is not addressed to scientists and experts on powers, but rather to common electrical engineers that sometimes face power related problems in nonsinusoidal systems.
