Question

Please show all steps. Thank you

write a program to calculate the efficiency and the maximum efficiency for your transformer (MATLAB)

Program must be written with MATLAB.

Below is the Flowchart for help

INPUT Used the flowing data to run your program, and check that it runs properly. TA = 10Kva 2200 220 s95 = 4.54A Constant power factor 0.85 lagging OUTPUT The output of the program must have the following columns and format: LOAD [kw] Pcu W] Pc W] Pin(kWh [96] The entry LOAD [kW] must decrease form 120% to 0% in steps of 5%. Determine (using Matlab) the value of maximum efficiency and its corresponding load value.

Explanation / Answer

Matlab code

clc;
close all;
clear all;
kVA = input('Enter kva =>');
Poc = input('Enter Poc =>');
PF = input('Enter PF =>');
Vp = input('Enter Vp =>');
Vs = input('Enter Vs =>');
Psc = input('Enter Psc =>');
Vsc = input('Enter Vsc =>');
Isc = input('Enter Isc =>');

IR = (kVA*10^3)/Vp;
REQp = Psc/(Isc)^2;
disp(' LOAD Pout Ploss Pin Efficiency');
for NSTEP = 120:-5:0
Pout = (kVA*10^3)*(NSTEP/100*PF);
Pscl = Psc*(NSTEP/100)^2;
Ploss = Pscl + Poc;
Pin = Ploss + Pout;
Eff = (Pout/Pin)*100;
A = [NSTEP Pout Ploss Pin Eff];
disp(A);
end
I = sqrt(Poc/REQp);
MaxEfficiency = (Vp*I*PF*100)/(Vp*I*PF+Poc+Poc)

%%end of code

inputs=>

Enter kva =>10
Enter Poc =>133
Enter PF =>0.85
Enter Vp =>2200
Enter Vs =>220
Enter Psc =>204
Enter Vsc =>95
Enter Isc =>4.54

Output Obtained=>

LOAD Pout Ploss Pin Efficiency
