Considering a three phase delta connected synchronous machine, the terminal line-line voltage is 1 p.u, the stator leakage inductance is 0.2 p.u, ignore the stator winding resistance, the rotor wind current is adjusted by a dc voltage source with a variable resistor.

1) Draw the single phase diagram of the machine;
2) If the machine is in the generation mode, draw the phasor diagram to show the phase terminal voltage, phase current, induced voltage, and voltage drop over the leakage inductance;
3) If the induced voltage EA is 1 p.u and the three phase active power delivered by the machine is 0.8 p.u, calculate the p.u. value of three phase reactive power generated by the machine.
