Comments on “Physical Interpretation of the Reactive Power in Terms of CPC Power Theory Revisited”


As the author of the CPC-based power theory I would like to recognize Drs. Jeltsema’s and van der Woude’s attempts aimed at formulating that theory in the time-domain, as presented in Ref. [1]. The CPC-based power theory was originally formulated in the frequency-domain, meaning with the use of a concept of harmonics and admittances for harmonic frequencies. Equivalent formulation of that theory in the time-domain would positively contribute to strengthening its fundamentals. Power theory of electrical systems is developed mainly for cognitive reasons: we would like to understand physical phenomena that accompany energy transfer. It is also developed for practical reasons: we would like to know how undesirable phenomena that accompany energy flow could be suppressed. The adjective “physical” in the name “Currents’ Physical Component”, (CPC), has therefore, a crucial importance. It means that each current component in the CPC-based power theory can be associated with a distinctive physical phenomenon in the circuit that can be observed by measurement. In this paper we will investigate if the current decomposition presented in Ref. [1] can be regarded as decomposition into currents’ physical components in the time-domain and its cognitive merits.
