A short link has a thermal rating of 1.0 MVA, and a phase impedance of 140 /50.7°. The receiving end voltage needs to be kept at 11 kV, and the sending end voltage must not be more than 10% above this when the link is fully loaded. Sketch a phasor diagram for the loaded link, and hence determine the active and reactive powers that could be delivered in this condition. 947 kW; 321kVAr lagging

Question
A short link has a thermal rating of 1.0 MVA, and a phase impedance of 140 /50.7°.
The receiving end voltage needs to be kept at 11 kV, and the sending end voltage
must not be more than 10% above this when the link is fully loaded. Sketch a phasor
diagram for the loaded link, and hence determine the active and reactive powers that
could be delivered in this condition.
