 Abstract
The Self Controlled Synchronous Motor (SCSM) is a good solution for variable speed drives at high and very high power ratings . Due to the complexity of the scheme the analytical simulation of this drive system is very difficult .In the paper is shown a new approach based on the Simulink Power System (SPS) library to generate an elegant solution for the simulation model. A SCSM drive system with GTO thyristors was studied and simulated in both steady state and transients showing good performance.

 Rezumat
Maşina sincronă autopilotată este o soluţie utilizată pentru acţionările electrice de mare putere ce necesită viteză variabilă.Datorită complexităţii schemei o simulare bazată pe ecuaţiile de funcţionare aeste foarte dificilă.In lucrare se arată o abordare nouă, bazată pe elementele din biblioteca Simulink Power Systems(SPS), ce permite o soluţie elegantă pentru modelul destinat simulării. S-a studiat un sistem de acţionare cu o maşină sincronă autopilotată şi convertoare cu tiristoare GTO în regim staţionar şi tranzitoriu, cu menţionarea unor rezultate în urma simulării.
