M. Dominguez et al., AN ADAPTIVE SCHEME FOR THE DERIVATION OF HARMONIC IMPEDANCE CONTOURS, IEEE transactions on power delivery, 9(2), 1994, pp. 879-886
The aim of this paper is to make the calculation of harmonic impedance
s accurate and efficient. An adaptive scheme is proposed which minimis
es the number of frequency samples to be used in the derivation of the
impedance/frequency loci. The scheme is then used to derive three-pha
se harmonic impedance contours which take into account any specified r
ange of fundamental frequency variation.
