The transient simulation functions are able to analyse the dynamic behaviors of small systems and large power systems in the time domain.
The transient simulation makes it possible to model complex systems like industrial networks and long transmission grids.
The process of performing a transient simulation includes the following steps.
1. calculation of initial values, including a load flow calculation
2. definition of result variables.
3. definition of events.
4. execution of simulation
