Instantaneous sinusoidal and harmonic active and deactive currents in three‐phase power systems

In this contribution a new decomposition of sinusoidal three‐phase currents is proposed. The main feature is that it leads to the compensation of non‐active currents partly by elements without energy storage and partly by means of linear elements with energy storage (inductors and capacitors). The proposed decomposition is compared with existing procedures, such as those developed by Akagi‐Nabae and by Czarnecki. The possible generalization of this concept to distorted voltages and currents is discussed.
