ZIP model for compressor motor

Hello,

I would like to model in one of the buses in my study case, a very large electrical compressor motor of 10MW. Can I use the ZIP model for modelling of this motor as load for dynamic simulation. I will oberserve the voltage drop in case of short circuit in nearby nodes and frequency drop?

Any advice if this is enough accurate? I am thinking of this because using the CIM5BL or other induction motor models would need a lot of parameters which I don't have.

Thank you

I would recommend to use CIMBL5 with typical data for a large motor, see Figure 21-1 in Program Application Guide Volume 2.

Thank you Perolofl, could you provide some typical model data, I am trying with some data but the model is not converging after adding CIM5BL dynamic load in PSS/E.

Have you reduced the time step. Try with 1 ms!

Thank you Perolofl. It worked by reducing the DELT value to 1ms.

I tried using CIM5BL with the following parameters : 154 'CIM5BL' 1 1 0.0048, 0.0744, 2, 0.0163, 0.0814, 0.0043, 0.0470, 0, 0, 0, 0, 8.8680, 0, 2.3960, 0.2, 12, 4, 2, 0.35/ and added the model to savnw.sav at node 154.
