Phase shift of three phase sinusoidal voltage?

Hi everyone,

I am sim ulating a microgrid in Simulink, and if I have a three phase sinusoidal voltage and I wish to phase shift it by varying phase shift. How can I do that?

I am trying to implement a control scheme for a three phase dc-ac inverter and I need to implement that phase shift on my three phase voltage

Appreciate any help!

Asmaa.

Use the sin wave block and use the "Phase" field on the dialog box to modify your phase.

Hi KL,

Thanks for your fast respond, I did not use the sine wave block to generate my three phase voltage. It is a generated three phase voltage form an ac source block. And I wish to phase shift that designated three phase voltage by a changing phase shift coming from a control scheme. I do not have the phase shift as a given number it will depend on my control scheme.

Thanks for the help tho, I hope is it clear now

It's been a long while I used simulink and simpower systems. If I remember correctly you should be able to enter a variable name in the field of "Phase angle of phase A", and you send your control signal to workspace and update the same variable. But I cannot remember if it would work and I also cannot test it, sadly.
