Rezumat
Aceasta lucrare analizeaza posibilitatea descompunerii curentului in circuite trifazate fara fir de nul pe baza
Teoriei Conservative a Puterii. In acest scop au fost analizate mai multe studii de caz prin simulare, in Matlab/Simulink,
pentru tensiune nesinusoidala si pentru sarcini liniare, respectiv, neliniare. Dupa interpretarea rezultatelor obtinute prin simulare, modelele de calcul create au fost verificate experimental, pe baza unui sistem real de filtrare activa.

Abstract
This paper analyzes the feasibility of decomposing the current in three-phase, three-wire systems using the
Conservative Power Theory. Several case studies were created to be analyzed by simulation in Matlab/Simulink
environment, under non-sinusoidal voltage conditions, taking into consideration linear and non-linear loads. After
interpreting the results obtained by simulation, the implemented computation models have been investigated using an
experimental active filtration system.
