modelTrafoMag
Magnetic coupling transformer, 3-phase dq0
Extends from Partials.TrafoMagBase (Base for magnetic coupling transformer, 3-phase dq0).
Information
Stray-impedance and resistance, with non-ideal magnetic coupling, i.e. non-zero magnetisation current
and eddy current losses.
Delta topology: impedance is defined as winding-impedance (see info package Transformers).
SI-input: values for stray and coupling impedances are winding dependent.
r[k] = R[k] x[k] = omega_nom*L[k] x0[k] = omega_nom*L0[k] redc = Redc xm = omega_nom*Lm xm0 = omega_nom*Lm0
pu-input: values for stray and coupling impedances are winding-reduced to primary side.
r[k] = R[k]/R_nom[k] x[k] = omega_nom*L[k]/R_nom[k] x0[k] = omega_nom*L0[k]/R_nom[k] redc = Redc/sqrt(R_nom[1]*R_nom[2]) xm = omega_nom*Lm/sqrt(R_nom[1]*R_nom[2]) xm0 = omega_nom*Lm0/sqrt(R_nom[1]*R_nom[2])
with
R_nom[k] = V_nom[k]^2/S_nom, k = 1(primary), 2(secondary)
