Abstract

A detailed formulation considering generator swing dynamics for small signal stability analysis of power system is presented. A reduced formulation obtained by decoupling voltage instability from angle instability is derived from the detailed formulation. The accuracy of prediction of voltage instability using the reduced formulation is investigated through the case study of a 10 machine 39 bus system. The effects of exciter gain and time constant are also examined and the results are presented. In addition, the effect of static var compensator (SVC) is also analysed through eigenvalue analysis. The results are also validated by system simulation.
