Hi Everyone,

I want to do dynamic simulation on the energization of generation transformer to investigate the effect of energization on system voltage.

Could PSSE be used to do such dynamic simulation?
The model data for a transformer used is shown in the following , I don’t know if the model could be used for dynamic simulation.

If not, could other elements (e.g. shunt reactor) be used to substitute the simulation of generation transformer?
How to determine the parameters of the substitute element for simulating the energization of generator transformer?

Thank you so much!

I think you usually use an EMT type program, e.g., PSCAD, EMTP, to perform energisation studies. You also usually tweak the transformer models with custom saturation curves to represent the transformers more realistically (either B-H curve or the equivalent V-I curve).
