Power transformer including iron losses with variable parameters
The VariablePowerTransformer is a two port with variable
parameters. The left port voltage v1, left port current
i1, right port voltage v2 and right port current
i2 are connected by the following relations:
v1 = R1 *i1 + jωL_1s *i1 + R_Fe*jωL_h/(R_Fe + jωL_h)*(i1 + i2')
v2' = R2'*i2' + jωL_2s'*i2' + R_Fe*jωL_h/(R_Fe + jωL_h)*(i1 + i2')
with:
v2'=w1_w2*v2; i2'=i2/w1_w2; L_2s'=(w1_w2)^2*L_2s; R2'=(w1_w2)^2*R2
This is the common way to describe power transformers.
All parameters are specified by independent input signals.
Attention!!!
To ensure that the phasor domain-based model works in a
quasi-stationary mode, all input signals may alter only very slowly
in comparison with both the nominal frequency f=ω/(2π) and
the dominant time constant of the phasor domain-based model.
