park transformation for single phase

I am trying to transfer alpha abd beta with theta angle through park transformation ?

can anyone tell me what is the expected o/p form park transforation of the single phase conncected to grid ??

thanks

To transform single phase voltages/currents to shift your voltage/current by 90 degrees and use this value as β and your original signal as α. This can then be converted to dq0 using library blocks available in simulink.

It is difficult to say what the expected output is without knowing about your system but, generally d and q are dc values.

Can you please attach the model (*.slx) and other files required to run it? Also, which version of Matlab are you using?

my matlab verion R2018b. i sent u simple model. i just want to make sure that the output of park transformation should be DC constant value.

Saif, I do not have access to 2018b. Please see the model attached.

Saif,

You can phase shift using the complex phase shift block. I have never used this block as I don't have the toolbox.

The other option is to take the derivative of the sine signal. As you may know: and
