(c) A transmission line, modelled through a series reactance X = 0.4 p.u., supplies an electrical load with active power PL = 0.4 p.u. and reactive power unknown. The two voltages at the sending and receiving ports of the line are controlled and their magnitudes are equal to V₁ = 1.02 p.u. and V₂ = 0.98 p.u., respectively. (i) Draw the phasor diagram of the system, assuming lagging current. (ii) Determine the reactive power consumed by the line and the reactive power sent at the port 1. Qline = 0.0684 p.u. Q₁ = 0.134 p.u.
