modelTrafoSat
Saturation transformer, 3-phase dqo
Extends from Partials.TrafoSatBase (Base for saturation transformer, 3-phase dqo).
Information
Stray-impedance and resistance, with non-ideal magnetic coupling, i.e. non-zero magnetisation current, eddy current losses and saturation.
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 xm_sat = omega_nom*Lm_sat, saturation value of inductance psi_sat, pu saturation value of flux (no SI-value!)
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]) xm_sat = omega_nom*Lm_sat/sqrt(R_nom[1]*R_nom[2]), saturation value of inductance psi_sat, pu saturation value of flux
with
R_nom[k] = V_nom[k]^2/S_nom, k = 1(primary), 2(secondary)
Saturation needs high-precision integration!
