Currents' physical components (CPC): Case studies in three phase systems

Abstract

In this article the CPC theory was implemented in simulation environment with the intention of discussing its application in different circuits and operating conditions. The analyzed conditions focus on three-phase three-wire systems, starting from sinusoidal supply with symmetrical voltages, balanced and unbalanced, linear and non-linear loads, evolving to asymmetric and non-sinusoidal supply voltage using the same load configurations. As a result of these possible variations, which represent the diversity in current electrical systems, it is necessary to survey, study and implement increasingly complex algorithms, in order to cover all these possibilities. The Currents' Physical Components theory was coherent for all circuits with linear time-invariant loads. For non-linear loads, however, there were unexpected power components, that is, they did not match their suggested physical interpretation. Therefore, further studies of these cases are necessary.
