I need to transform from the alpha beta 0 reference frame to dq0 reference frame to verify some dynamic performance from different reference frame system . And I dont see it in PSCAD main Library or in example files. Should I go with the hard way to code it myself ?
Thanks

Hi Hasan,
I tried to create simple simulation using :
1. ABC -> DQO transformation block from PSCAD library
2. Clarke and Park transformation from Example of Machine Drive.
Why does it show opposite direction for quadrature (q) ? Which one is correct ?
I also saw the Question from another person in http://forum.hvdc.ca/930754/abc-dq0-t...
but I still cannot understand how to modify the PLL to get the same value in quadrature
Thanks, Aji

Just got it from Machine Drive example.
If you have another library, please let me know.
Thanks.

Hi there
When you use abc block transformation to dqo, you will need a transformation angle that will be found from PLL. In the same way can be used for alpha beta
You should determine in the transformation block that which type of transformation you are looking for
