SimPowerSystem block Asynchronous Machine parameter values

I am using SimPowerSystem block Asynchronous Machine SI Units. I want to analyze this block.In option "Look under the Mask" there are many subsystems.There are many parameters in those systems like SM.Tb1, SM.Rr, SM.p SM.ctrl etc. What is SM here? Where to get details of these parameters?? Where I can set these parameters or change them...

Answer 1

[Rongyu Zha]

Have you solved that? Got the same problem.

Answer 2

[Arnaud Miege]

That's a duplicate of a previous question that's already been answered.

But my problem is still same... :(

[Arnaud Miege]

And the answer is still the same... The parameters are generated in the mask initialization callbacks with the the powericon function:

block = gcb;

[Ts,SM,WantBlockChoice,X,Y,txt] = powericon('AsynchronousMachineInit',block,TsPowergui,TsBlock,MechanicalLoad,RotorType,ReferenceFrame,NominalParameters,Stator,Rotor,Cage1,Cage2,Lm,Mechanical,PolePairs,InitialConditions,Units,SimulateSaturation,Saturation,IterativeModel);

powericon('SetInternalModels','set',block,WantBlockChoice);

[Arnaud Miege]

These parameters are calculated automatically based on the values you enter in the mask of the Asynchronous Machine block, you can't change them.

Arnaud Miege: i found the "previous question" you mentioned, but it still get some error. Actually i am fighting with the model of Synchronous Machine pu Fundamental, and when i run powericon manually, it keeps telling me some variables are undefined, such as "Units", which can be found in "Parameters &　Dialog" but cannot get the value, so please tell me how to get the value of those popup variables, thanks a lot !

Answer 3

[Ahsan Naeem]

Thanks a lot dear... But actually I want to know what is SM.web parameter for example in reference to Electric Machine Theory.... And so all other parameters...

[Kaustubha Govind]

Ahsan: It's not clear what you don't understand about the answers that Arnaud and I have given. We have both explicitly answered how you can get the value of SM (and there the values for SM.Tb1, SM>Rr, etc.). Have you tried our recommendation of using the powericon function? If yes, what difficulty do you face?

[Arnaud Miege]

The parameters are just that, parameters. they can be changed to whatever value you like. You'd be better off trying to understand the underlying structure of the mathematical model and relating this to the theory, then it would make much more sense what the parameters are used for. The SimPowerSystems documentation is a very good place to start.
