An Analysis of Regimes of Parallel Generators Operation in Wind Turbine System
Voncilă, Elena; Costin, Mădălin; Voncilă, Ion; Nechita, Cristian; Fetecău, Grigore (Universitatea "Dunărea de Jos" din Galaţi, 2011-07)The parallel connection of different types of AC generators, used as example in isolated sites, represents a difficult problem due to the different particularities of the that generators involved. This paper analyses the ... -
Comparison of Three Phase 4-Leg Shunt Active Power Filter Using DQ, Indirect and Maximum Control Method
Bălănuţă, Ciprian; Gurguiatu, Gelu; Munteanu, Toader; Fetecău, Grigore ("Dunarea de Jos" University of Galati, 2011)In this paper is presented a comparative analysis of three control methods for a thee-phase active power filter (APF) with four legs, aiming at the power quality indicators: THD, power factor, unbalance. -
Considerations on the Effect of Plastic Deformation Over the Magnetic Behavior of Soft Ferromagnetic alloy FE-3%SI NO
Fetecău, Grigore; Iordache, Viorel-Eugen; Hug, Eric (2002)The paper synthetically presents the results obtained over the degradation of magnetic properties of soft ferromagnetic sheets Fe-3%Si NO required mechanically in plastic deformation area. Chronologically, the evolution ... -

Improving the Power Factor at Unbalanced Consumers
Bălănuţă, Ciprian; Munteanu, Toader; Fetecău, Grigore ("Dunarea de Jos" University of Galati, 2010)Unbalanced consumers have led to power quality problems. It is therefore necessary to have on hand solutions and equipment capable of improving the power quality. This paper provides a comparison on improving the power ...
