Description

pict

This block transforms a three-phase signal [xa xb xc]   into a two-dimensional vector [yα yβ]   in the stationary reference frame:

       ⌊  2    1    1  ⌋  ⌊   ⌋
[y  ]  |  -  - -   --  |  | xa|
  α  = |⌈  3    3    3  |⌉ ⋅|⌈ xb|⌉
  yβ       0  √1-  - 1√--
               3     3      xc

Any zero-sequence component in the three-phase signals is discarded.
