Motor starting dynamics of pump storage
Is it possible to simulate the motor starting dynamics when a pump storage is operated in pumping mode? Is there a PSS/E dynamic model that can be used to simulate this phenomenon?

The motor models presented here are for induction machines. I don't think they can be used to simulate pump storage motor starting.
Yes, you are right. Here we are talking about a synchronous motor, i.e. a generator with negative generation. One way to simulate is to have a generator with Pgen=0 in load flow and to start ramping the generator with negative Pmech during the simulation. Note, the generator must be on-line in LF.
Thank you. You mentioned negative Pmech. So this means a governor model should also be present? I tried this approach (Pgen = 0, generator online in load flow) and changed the Pgen to a certain negative value during dynamic simulation. I guess there was an error when I did that method.
Pgen is not used in dynamics. Use a governor model to change Pmech to negative values during simulation. Change Gref to negative value.
Thank you. What governor model can be used where the change of Gref is allowed? I am using WPIDHY but it does not have a Gref parameter.
