Hi,
I have a three synchronous generators connected model with an error:
Invalid setting in 'WSCC/G1/G1/Electrical model/Synchronous Machine Continuous Model/Phimqd/1//Ll_q' for parameter 'Gain'.
Caused by:
  • The parameter supports only finite values.
Anyone have thoughts how to resolve this?

I had the same issue. I think this is due to a division by zero. You certainly defined a variable in your gain which is by default = to zero. Try to give a value for you variable.

Solution: Modify the parameters of G1 synchronous motor and reduce the original data of Xd and Xq. I fixed the error by changing these two parameters.
