Abstract

Summary: This article proposes a comparison between mathematical modeling and experimental results of the electric interactions of a synchronous and an induction generator. The electric system is composed by a synchronous generator operating in parallel with the induction generator, both through a common bus, connected to nonlinear loads. Measurements are made at several points for different system configurations presenting the repowering effect. The analysis of the harmonic flow and the sensitivity of the system parameters are performed. To make predictions in the system, a validated computational model with experimental data is proposed. The results obtained comparing the mathematical modeling and experimental tests show the increase of the active power by the induction generator, as well as the circulation of harmonic currents in the common bus. The results obtained through the computational model present predictions of load unbalance and increase in the system harmonic distortions. The sensitivity analysis confirms the induction generator influences on the system harmonic flow.
