2019-04-19 09:31:55 -0500 asked a question Exceed the dimensions of working memory in PSS/E V33

Dear forum users,

I am trying to use PSS/E V33.4 (it is a full version) to open a case file (.sav) and have the following error message.

&&&&&&&&&&&&&&&&&&&&&&&&&&&&

Total Allowed Description 693 560 Wind Machines

The saved case in file XXXX exceed the dimensions of working memory.

&&&&&&&&&&&&&&&&&&&&&&&&&&&&

I don't know why the full version has such a limit. Can anyone suggest what I can do to remove this limit?

Thank you!

Hi perolofl,

Thanks for your reply!

Can you help me to take a look of my case file?

Dear forum users,

I have a very simple circuit shown as attached (google drive). Power flow study runs fine. But I got issues with the dynamic simulation. Here is what I did for the dyna simulation, after the initialization, I let the circuit run for 1sec. then I created a three-phase fault on bus 1100, then clear the fault after .1 sec. then run the circuit to 2sec. I found after the dynamic simulation, the generator and transformer on bus 1111 are all not in service anymore.

Can anyone suggest what went wrong? Thank you!

Dear forum users,

I am new to PSS/E and Python. I run a PSS/E dynamics simulation for a sequence of fault/clear event. After the simulation is done, I notice some bus/ generator are not in service anymore. And the simulation result is not what I have expected, most likely wrong. Any suggest on this, what did I am missing in the model? As I said, as a new user, I am not sure if I formulate my questions correctly.

Thank you very much!
