modelYDportTrafo_p_n
AC two port with Y or Delta topology for transformers
Extends from Port_p_n (AC two port, 3-phase).
Information
Defines Y- and Delta-topology transform of voltage and current variables and contains additionally voltage and current scaling.
Below
term, v, i, w
denote either the 'primary' or 'secondary' side
term_p, v1, i1, w1 term_n, v2, i2, w2
Definitions
v: scaled voltage across conductor i: scaled current through conductor v_n: voltage neutral point if Y-topology i_n: current neutral to ground if Y-topology w: voltage ratio to nominal (any value, but common for primary and secondary)
Relations Y-topology, (v, i: terminal to neutral point)
v = (term.v - {0, 0, sqrt(3)*v_n})/w
term.i = i/w
i_n = sqrt(3)*term.i[3]
Relations Delta-topology, (v, i: phase terminal to phase terminal)
v[1:2] = sqrt(3)*Rot*term.v[1:2]/w v[3] = 0 term.i[1:2] = sqrt(3)*transpose(Rot)*i[1:2]/w term.i[3] = 0 with Rot = rotation_30deg
