How can I use just the "d" component of the output of a abc-to-dq transformation?

Hi,

I have a circuit on simulink like the one of the image bellow and I want to 2use the "d" component of the block abc-to-dq-transformation. I tried to use somes buses, like the "bus selector" but this block dont show me any signal in the bus to select. Probably because the output of the dq0 block is a vector. How do I get each component of this vector isolated then?

Thanks in advance.

Use a Demux block

With the demux block, the first output port of the demux (counting from the top) is the "d" component? This block doesn't presents the name of the "signal" like the bus selector.

Thanks!

The first component is d , just follow the order d q o

Hi Sir,

can you please suggest the reason for getting id component zero in abc park transformation.Its rotating alignment is kept 90 degrees behind A axis.I am trying to do reactive power compensation in microgrid.
