ESTUDO DOS FATORES DE SENSIBILIDADE PARA CORRIGIR OS NÍVEIS DE TENSÃO ATRAVÉS DA ALOCAÇÃO DE REATIVOS NO SISTEMA ELÉTRICO DE POTÊNCIA

Abstract

This work purposes an research of an optimization method to enhance the active power transfer in electric system and minimize the power reactive flow, assuring the optimization of voltage bars in the power electrical system. The definition of which actions will be taken in a way to minimize the reactive flow can be realized through the Sensitivity analysis. The objective of this work is to present an methodology to correct the voltage levels in a power electrical system through the load flow method that uses the Jacobian Matrix of Newton Raphson's method to calculate the Sensitivity factors, and through the Sensitivity Matrix create a linear program to allocate the critical reactive bars of the system. Were made studies to validate and verify the purposed approach of the system of 4 bards in Matlab Software. With possession of the simulation results note a correction voltage of the system critical bars, raising tensions near the limit set validating the method proposed in this paper.
