Is it possible to run the power_wind_dfig model with ZERO speed?

I want to run the power_wind_dfig model starting at zero speed. The problem is that when I try so, the speed goes to -0.2 pu and the results don't make sense. Even with increasing wind speed, I cannot make the machine speed positive.

Hi Sahand,
Can you share how did you configure the model to start from 0 speed?
For this shipping example, the initial condition is defined by a .mat file. And the model has defined a InitFcn callback to load the inital values, where the inital motor speed is defined 0.993pu. Everytime when you hit run, it will load this .mat file.
One way to change the inital motor speed is to define the xInitial in 'PreLoadFcn' callback, and modify the inital motor speed to 0 by run this in the commond before run the model:
>> xInitial.signals(44).values = 0;
Here is the simulation result of motor speed with 0 inital:
Hope this is helpful!
Best,
Christine

Hi Liasi,
Can you elaborate more about "The problem is that when I try so, the speed goes to -0.2 pu and the results don't make sense. "? and would you be able to start from zero speed, if not, what error message did you get?
Thanks,
Christine
