| Description | A generalized time-domain definition of electric power, using autocorrelation and cross-correlation techniques, is proposed for measurement, characterization and compensation of fictitious power in any network, under conditions of nonsinusoidal and in general aperiodic voltage and current waveforms. This leads to the proposal of a new equivalent network parameter, disseptance, which describes the nonlinear properties of the load. The problems associated with the existing definitions of electric power are pointed out by means of a descriptive summary of the different power definitions and their associated limitations. A new philosophy for compensation of fictitious power in distorted supplies, is based on this definition of power and network parameters. ’n Algemene tyddomeindefinisie van elektriese dry wing, wat van outokorrelasie- en kruiskorrelasietegnieke gebruik maak, word voorgestei vir die meet, karakterisering en kompensasie van fiktiewe drywing in enige netwerk, onder toestande van nie-sinusvormige en in die algemeen aperiodiese verlope van stroom en spanning. Die definisie lei tot ’n nuut gedefinieerde, ekwivalente elektriese netwerkparameter, disseptansie, wat ‘n aanduiding is van die nie-lineêre eienskappe van die elektriese las wat aan die netwerk verbind word. Die probleme wat met die huidige definisies ondervind word, word dear middel van ’n opsommende beskrywing oor die bestaande definisies en hulle onderskeie tekortkomings uitgelig. ’n Nuwe filosofie vir die kompensasie van elektriese netwerke, waarvan die stroom- en spanningsverlope vervorm word deur nie-lineêre lasse, word gebaseer op hierdie algemene definisie van elektriese drywing. | |
