I. Define the Situation:
A synchronous generator with the parameters given above is operating with constant mechanical torque, Tm, equal to 0.7 pu and delivering power to an infinite bus.
Assume that:
II. Desired

Using analytical methods (not simulation) calcuate the:
III. Solution
1. Calculate the critical clearing angle, δcr.
a. Calculate the initial rotor angle, δ0.
b. Calculate δmax.
The following is only valid for round rotor machines.
c. Calculate δ.cr.
Initial guess:
