Models of synchronous generator and transformers for Dispatch Training Simulators and Real Time Digital Simulators

This paper is aimed firstly to own-made dynamic models of synchronous generators (SG) for Dispatcher Training Simulators (DTS). The basic requirements are contending claims from mathematical physical description and the numerical solution point of view on the other side. From this fact yields necessity of “engineering intuition” and experiences. Secondly the model of power transformers (PT) is evaluated for Real Time Digital Simulators (RTDS), which are aimed to design and verification of digital protections and local automatics. It is most important especially in analysis of intersystems swings, abnormal and warning state, near critical state, blackout and restoration of power systems.
