Sensitivity Analysis Of The Synchronous Generation Repowering System In Parallel With Induction Generator

In this work, it is proposed to calculate the sensitivity of parameters, based on analytical calculation, of repowered system between two electric generators, an induction generator and a synchronous generator, connected to a common bus in permanent regime, subject to a non-linear load. It is proposed a repowered system with simulated data where, based on percentage variations in the base values of the parameters, measurements are made for the analytical calculation that expresses the impact at the output caused by variations in the input. The experimental tests confirmed quantitatively the most sensitive variables for the system for the interval of interest. The results show that the generators and the nonlinear load are the input parameters with the highest sensitivity in the active power output and that the synchronous generator is responsible for the greater sensitivity in the reactive power output.
