Contents

A concept of equivalent circuits of three-phase unbalanced loads supplied with symmetrical and with asymmetrical voltage is discussed in the paper. In particular, it is shown that there is an infinite number of equivalent circuits of unbalanced loads supplied with a symmetrical voltage but there is only one equivalent circuit if the voltage is asymmetrical. Also, a method of dynamic identification of the equivalent parameters of unbalanced loads with asymmetrical supply voltage is discussed in the paper.

Übersicht

In dem Beitrag wird ein Konzept für Ersatzschaltbilder dreiphasiger Schaltungen mit unsymmetrischer Belastung erörtert. Insbesondere wird gezeigt, daß es für solche Belastungen bei symmetrischer Spannungsversorgung eine unbeschränkte Anzahl von Ersatzschaltungen gibt, jedoch nur eine, wenn eine unsymmetrische Spannungsversorgung vorliegt. Weiterhin wird ein Verfahren zur Identifikation der Parameter unsymmetrischer Belastungen mit unsymmetrischer Versorgung diskutiert.
