Explain what a Long Transmission line is. What can be the result
of a lagging and leading load with regards to the Sending end
voltage, Sending end Power, efficiency and voltage regulation?
Explain why the positive sequence impedance of a transmission
line and transformer is the same as the negative sequence impedance
but is different from the zero sequence impedance.

Write about wireless transmission and explain how’s the
transmission is occurred, what are the current technologies is
applied to such systems and its conclusion
Consider a salient-role generator delivering power
through a short transmission line to an infinite bus V∞=1∠0°,
|Ea|=1.5. The active power delivered to the infinite bus is 0.7. We
are given the generator reactances Xd=1.6 and Xq=1.0 and the line
reactance XL=0.3. Neglect resistances, draw the phasor diagram and
find Ea and Ia.
