Parametric Regression Applied for Determination of Electrical Parameters of Synchronous and Induction Generators Operating in Parallel on the Electrical Energy Repowering System

The purpose of this work is to determine the values electrical parameters synchronous and induction machines validate interactions between an generator a generator. generators are connected in two ways: (i) isolated from common bus (ii) parallel steady state, subject nonlinear load. They old refurbished machines; thus, parametric regression methodology used parameter values. After computational model validation, analyses performed by various system configurations confirm repowering analyze harmonic current flow. results obtained comparing computer simulation experimental tests prove that validated represents real system. With experimentally model, it possible verify occurrence increased value distortions terminals, acting as preferential path for currents.
