Good day everyone,
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?
