I'm trying to simulate a single phase transformator by using Simulink.

I've got the current values:

R1 = 3 Ohm

R2 = 0.03 Ohm

X1 = 6.5 Ohm

X2 = 0.07 Ohm

Rc = 100k Ohm

Xm = 15k Ohm

f = 60 Hz

Uprim = 2400V

Usec = 240V

S = 29kVA

cos Phi = 0.8

And I've made the current calculations:

L1 = X1/2*pi*f = 17,24 mH

L2 = X2/2*pi*f = 185.68 uH

Lm = Xm/2*pi*f = 39.79 H

S = Urms*Irms => Irms = 120.83 A

P = Urms*Irms*cos Phi = 23200 W

Q = Urms*Irms*sin Phi = 17400 VAr

Q>0 so Q = ohms-inductive => QL = 17400, QC = 0

I've put the following parameters in my transformator:

Nominal power(VA) and frequency: [29000 60]

Winding 1 parameters V1(rms), R1, L1: [2400 0 0], 0 because that is the ideal value and I've already put R1 and L1 in my circuit.

Winding 2 parameters V2(rms), R2, L2: [240 0 0], 0 because that is the ideal value and I've already put R2 and L2 in my circuit.

Magnetization resistance and inductance: [Inf Inf], Inf because that is the ideal value and I've already put Rc and Xm in my circuit.

I've put the following parameters in my LOAD:

Nominal voltage (rms): 240

Nominal frequency: 60

Active power (W): 23200

Inductive reactive power QL (positive VAr): 17400

I've made the current circuit and simulated it, but somehow my secondairy output voltage is only at 223.77 Vrms.

Can someone explain to me why that's the case? Did I do something wrong in my calculations or in my simulation?
