Power System Analysis I

A 3-phase line is represented by nominal-$\pi$ model. The series impedance of the line is $12+j65\,\Omega/\text{phase}$ and shunt admittance is $j2.5\times10^{-4}\,\mathrm{S}/\text{phase}$. Compute the power delivered to a load at the receiving end and construct the phasor diagram for the line if the sending end voltage and current are:

$V_{S,L}=1385\angle 15.2^\circ\,\mathrm{kV}$ $IS,L=225\angle 18.3^\circ\,\mathrm{A}$
