High Fidelity Simulation

Accuracy of the simulated phenomena has been proven by extensive comparisons with EUROSTAG®, providing an implicit validation of FAST

FAST relies on rigorous solutions and therefore, simulation remains quantitatively exact in all circumstances, with accuracy similar to an advanced study tool like EUROSTAG®.


Typical range of phenomena covered by FAST goes from oscillations at about 10 Hz up to quasi static evolution and also includes incidents like:


  • Short circuits
  • Power swings
  • Losses of synchronism
  • Frequency and voltage collapses
  • Loop flows, overloads and transmission corridor tripping (cascading effect)
  • Main protective device actions and backup tripping in case of breaker failure
  •  Black-out and black start
  • Power plant dynamics
  •  ... and more
