Budeanu's Reactive Power and Related Concepts Revisited

Comparative analysis of reactive power definitions in the presence of harmonics

“…Prema tome, prilikom definisanja reaktivne snage izdvojili su se različiti koncepti [5] koji su dalje razmatrani u ovom radu.…”

“…Osnovna zamerka ovoj definiciji jeste što redukcija ili eliminacija QB ne dovodi uvek do smanjenja gubitaka snage. Willems je pokazao u kojim slučajevima se kompenzacijom snage QB postiže smanjenje prividne snage, odnosno smanjenje gubitaka [5].…”

The measurement of actual apparent power and actual reactive power from the instantaneous power signals in single-phase and three-phase systems

“…Their definitions under nonsinusoidal conditions are still a matter of debate, and different approaches have been proposed with the aim of identifying new quantities able to exhaustively describe the properties of the power [1][2][3][4][5][6][7][8][9][10][11][12][13][14]16,17]. Most of the formulated theories were based on a particular type of reactive energy compensation, which has influenced the definitions.…”

“…This manuscript is placed in the complex and extensive field concerning the representation of power behavior in electric systems under non-sinusoidal conditions. Many authors have investigated and debated this topic, proposing different definitions for power quantities [1][2][3][4][5][6][7][8][9][10][11][12]. This work can be considered a small contribution to this field.…”

Survey about Classical and Innovative Definitions of the Power Quantities Under Nonsinusoidal Conditions

“…Starting from the given definitions of P and S, in the past years many researchers focused their attention on the definitions of the apparent power Q under nonsinusoidal conditions, proposing interesting and valid theories [3][4][5][6][7][8][9][10][11][12][13]. Unfortunately they reached different conclusions, also because different were the objectives of their works (system modelling, measurement, load control, energy pricing, filtering and so on) [14][15][16][17][18][19][20].…”
