What block to use to transform a three-phase signal into a two-dimensional vector in the stationary reference frame?

Hi,

I'm trying to simulate a three-phase star connected circuit using SIMSCAPE and I need to transform a three-phase signal into a two-dimensional vector in the stationary reference frame. I've only found a block that preforms a Clarke transformation from a three-phase (abc) signal to a alpha-beta-zero SRF, I need one that does the exact same thing only to a alpha-beta SRF.

In general, composite three-phase ports (represented by the single signal line) can only connect to other composite three-phase ports. However, expanded three-phase ports can connect to other Simscape Power Systems components.

Three-phase signals can be combined and separated with the "Phase Splitter" component. Therefore, you may combine three separate signals emanating from other Simscape Power System components into a composite three-phase signal with this. More information on this block can be found here:
