Power transmission lines

A transmission line of impedance (0.05 + j0.02) pu interconnects the buses of a switchyard and
a bulk supply point. The receiving end apparent power is (1.0 + j0.6) pu and sending end
voltage, 1/0°pu. Estimate the following:
a) receiving end voltage after two iterations
b) perform two further iterations to test the convergence of the value of receiving
end voltage deduced in a)
b) load current
c) sending end apparent power
