Abstract
This thesis describes a study into the field of electrical power theory and specifically deals
with the description and determination of power components in nonlinear electrical networks.
A general description of fundamental power theory is given and the basic philosophy of
fictitious power compensation ( according to Frryze ) is dealt with. The contributions of
Budeanu, Nowomiejski, Enslin and others are described. The description of Czarnecki was
found to be a good model for determining energy flow and power components in general
power systems. It is shown how the Czarnecki power components can be calculated from
practical noise infected data. A computer program was written for this purpose and is given
in conjunction with two case studies. Relationships between power theories, power factor
correction and general compensation are stated in principle. Certain power calculation errors
as well as negative effects that can impair effective energy transfer and compenation are also
discussed.
