A three-phase synchronous machine was, and still is, one of the most important element in today’s power generation systems (operating as a generator) or in distribution–load systems (operating as a motor). Thus, a suitable and detailed model is required to be used by students and future engineers in order to deal with transient stability analyses. For this purpose, the paper presents and analyses a procedure by which the mathematical modelling of a three-phase, four-pole, synchronous machine can be implemented in the LabVIEW environment. A suitable graphics user interface is proposed and case studies under different machine operating conditions are shown. The corresponding results illustrate the validity and accuracy of the model. Furthermore, a reactive power PI controller is also implemented. The overall graphics user interface/simulation model is applied to an undergraduate course as a teaching tool and assessed thoroughly. It is shown that the proposed tool may be utilized in under/post-graduate studies as well as in power utilities practician engineers courses.
