Dq reference frame

  1. Jul 31, 2013 #1
    Each VSC station has the same configuration, and its vectorbased equivalent circuit in the synchronous dq reference frame is shown in Fig. 1(b).

    Could someone please explain me what doe "dq reference frame" mean?

    Is it not just talking in terms of phasors? When you use phasors for AC descriptions, you choose to 'freeze' the axis, synchronous with the supply frequency. This VSC system involves two different frequencies (?) so one side's phasors will rotate slowly around the reference axes of the other side, if they are not synchronised.

    Hello! Thanks for response. But I am still not clear.

    Are you familiar with Phasors? (Not the Star Trek ones!)
