Repowering of a synchronous generation plant by induction generator

This work proposes itself through mathematical modeling, simulating the electrical interactions between two electrical generators, an induction generator and a synchronous generator connected to a common bus in steady state, subject to non-linear load. By comparing the modeling of the two machines, we can see that the induction generator will present best way for the harmonic currents flowing in common bus. Experimental tests have confirmed the results of comparative modeling of the electric generators. It was evident that the induction generator, in addition to increasing the active power to the electrical system, could reduce current harmonics components present at the connection point improving the voltage profile in the network.
