Linear Yy0 Transformer (Deprecated)

Purpose

3-phase transformer in Yy0 connection

Description

pict

Implements a linear three-phase transformer with two windings in Yy0 connection using three Linear 2-Winding Transformers. The magnetization inductance Lm   and the core losses Rm   are modeled as linear elements. Their values are referred to the primary side.

Parameters

Leakage inductance
A two-element vector containing the leakage inductance of the primary side L
 1   and the secondary side L
 2  . The inductivity is given in henries (H).
Winding resistance
A two-element vector containing the resistance of the primary winding R1   and the secondary winding R2  , in ohms (_O_  ).
Winding ratio
The ratio n1∕n2    between the number of turns of the primary and secondary winding.
Magnetization inductance
The magnetization inductance L
  m  , in henries (H). The value is referred to the primary side.
Core loss resistance
An equivalent resistance Rm   representing the iron losses in the transformer core. The value in ohms (_O_  ) is referred to the primary side.
Initial currents wdg. 1
A three-element vector containing the initial currents on the primary side [i1,a i1,b i1,c]   in amperes (A). The currents are considered positive if flowing into the transformer. The default is [0 0 0].
Initial currents wdg. 2
A three-element vector containing the initial currents on the secondary side [i2,a i2,b i2,c]   in amperes (A). The currents are considered positive if flowing into the transformer. The default is [0 0 0].
