Reconditioning in synchronous operation with one parallel induction generator

Abstract

The purpose of this paper is to compare mathematical modeling and practical bench in order to validate the electrical interactions between an induction generator and a synchronous generator. Two generators was connected to a common bus in steady state, subject to non-linear load. The results comparing modeling and bench tests show that the induction generator besides the active power increasing, has a better way for harmonic currents flowing in common bus. It was concluded that the induction generator repowering and attenuates current harmonic components present at the connection point, improving the network voltage profile.

Experimental study of induction generator as a repowering solution

“…The repowering between synchronous and induction generators connected to the common bus in steady state, subject to nonlinear loads is presented in Magalhães et al Magalhães presents the connection of synchronous generator and induction with the same power and of different powers, having the primary machine connected to the same bus of generators. Results show repowering of system and harmonic reduction in the common bus when the induction generator and synchronous generator are connected to the same bus.…”
