Controle de tensão no fluxo de potência continuado – modelagens e efeitos na estabilidade de tensão

Abstract

This paper proposes to model both the automatic tap control and the secondary voltage control in the continuation power flow problem, as well as, to evaluate the effects in the voltage stability due to the insertion of these control strategies. Maximum and minimum operative limits of each control device are taken into account. Modal analysis results are utilized in order to identify the system critical buses.
