Nonsinusoidal conditions in modern power systems
require special definitions to quantify power. A clear
physical interpretation of different conditions, leading
to different phenomena, is essential to enable
engineers to relate power measurements to meaningful
physical manifestations in the power network with the
objective of tariff implementation and the design of
compensation strategies. L.S. Czarnecki originated a
number of unique power definitions in the frequency
domain that conform very well to these requirements.
Unfortunately an important, but hitherto neglected
deficiency appears to be present in the Czarnecki
definitions: Under practical conditions, the summation
of power in three-phase networks with distorted
waveforms yields erroneous results. This paper
investigates this important inherent deficiency of the
Czarnecki power theory.
