RESUMO

In this work, the influence of load torque-speed characteristics on voltage stability of a system composed by an induction motor fed by a infinite bus through a transmission line is studied by employing eigenvalues and bifurcation analysis. Three types of load torque dependence on the rotational speed are considered by using a first and third order models: quadratic torque model, linear torque model and composite torque model. The results are compared with the ones obtained by considering constant torque model (independent on speed), in order to validate the static approach based on load flow equations
