Perhaps sb is able to point in the right direction. The task is to calculate the value of the receivig end volatge, for a load of 10 MW at 0.9 pf taken from 66 kV substation.
First I calculated the transmission line impedance
Zlinebase=(Vbase^2)/MVAbase
Zlinebase=132^2/100=174.24Ohm
Zlinepu= 150/174=j0.862
Sbase= 100 MVA
Load impedance = S=P+jQ
S=10+j4.84
Spu=0.1+j0.048 MVA
T1= j0.1 pu and T2= j0.12 pu
So the total impedace = T1+T2+Line+Load= j0.1+j0.2+j0.862+ 0.1+j0.048= 0.1+j1.21 ohm
Is that correct?
I know that the received volatge is Vr= Vs  Voltage drop. But how can I find the voltage drop? I need current for that, so how to find current?
Any help appreciated.According to matlab simulation the received voltage shoud be 57kV Line rms. Is that correct?
