The per-unit power output of a salient-pole generator which is connected to an infinite bus, is given by the expression:
P = 1.4 sin(δ) + 0.15 sin(2δ), where δ is the load angle. Newton-Raphson method is used to calculate the value of δ for P = 0.8 pu. If the initial guess is 30°, then its value (in degree) at the end of the first iteration is:
Correct : c
