Abstract

This paper presents the results obtained when using three different models of the asynchronous machine. The first order model is used to determine the steady-state performance when the rotor of the machine is fed with different direct- and quadrature-axis components of control voltages. The third and fifth order models are simulated and implemented into PSCAD/EMTDC software. These models are used to determine the dynamic behavior of the asynchronous machine when it is connected to an infinite bus and operating with normal conditions. Also, they are used to determine the performance when the induction machine is subjected to three-phase symmetrical faults.
