Teoria mocy biernej i mocy odkształconej według Budeanu - nowe spojrzenie

Budeanu’s concept of reactive and distortion power for systems operating under nonsinusoidal conditions has been subject to criticism throughout the past decades, which finally led to its removal from the latest standards. Recently, some new results are presented that shed a different light on Budeanu’s reactive power and its compensation. In this paper, a further analysis is presented to reveal the possibility to endow Budeanu’s reactive and distortion powers with physical meaning. For linear and time-invariant systems it is shown that Budeanu’s reactive power is representing the mean value of the moving average of the difference between the total magnetic and the electric energy. Budeanu’s distortion power, after an appropriate decomposition, represents a measure of the power fluctuations around the active power and Budeanu’s reactive power.
