I am trying to simulate Fault Induced Delayed Voltage Recovery by motor stalling. I see that the family of ACMTBL models have that capability. Does anyone know where i can find sample parameters for this model, or for any induction motor model with stalling capability.
In my experience (in the USA) the typical model we use for loads which can simulate FIDVR is the CMLDxx composite load model family. If you are dead-set on ACMTBL then I won't be able to help, but if you can use the CMLD model, then I can provide some typical parameters. See the model following my post.
You'll need to update the bus number and load ID. You can adjust the fractions of each motor type at CONS J+18 through J+22. The Motor D stalling parameters begin at CON J+103.
There is an absolute ton of material out there on these CMLD models, and I highly recommend reading some of it to ensure you are using the model as intended.

thanks! i am not dead set on the ACMTBL model, just looking for a load model with which i can simulate FIDVR. Will try it and see. By tons of literature, do you mean the stuff in PAGV2? Can you recommend other sources?
Here is a paper that NERC's Load Modeling Task Force put out: https://www.nerc.com/comm/PC/LoadModelingTaskForceDL/Dynamic%20Load%20Modeling%20Tech%20Ref%202016-11-14%20-%20FINAL.PDF A quick google of CMLD model also showed a bunch of other material. Hope that helps!
The model works fine if i implement it a single load bus. However, when i do this for all load buses in the IEEE 39 case, i get convergence errors right at initialization, with all the exciters and governors out of limits. Timestep : 0.00008333, acceleration factor: 0.3. Any advice on this?
