RTE-Drive Measurements
Block
Description
The RTE-Drive ABC-DQ block performs the abc to dq transformation on a set of three-phase signals. It computes the direct axis Vd and quadratic axis Vq quantities in a two-axis rotating reference frame according to the following transformation:
Vd = [ cos(θ) * (2*Vab+Vbc) + sqrt(3) * Vbc *sin(θ)] / 3
Vq = [ sin(θ) * (2*Vab+Vbc) - sqrt(3) * Vbc *cos(θ)] / 3
The transformation is the same for the case of a three-phase current; you simply replace the Va, Vb, Vc, Vd and Vq variables with the Ia, Ib, Ic, Id, and Iq variables.
