Abstract

In this paper, an approach for investigation of the transient behavior of a synchronous generator is developed and described in details. This model has been built up, systematically, by means of basic function blocks found with MATLAB/SIMULINK. This model is described in similar but modular approach as in electrical machines theory. This approach enables the researcher to calculate or investigate any motor variables; voltage, current, speed and torque. This model could also be used for a wide range of horse power needed in scientific research and numerical applications. A q-d axis based model is proposed to analyze the transient performance of synchronous generator using rotor reference frame. The motor stator voltage, the stator and rotor currents, the developed torque and rotor speed were plotted for full-load and no-load operating conditions.
