During a disturbance on synchronous machine, the rotor swings from A to B before finally settling down to a steady state at a point C on the power angle curve. The speed of the machine during oscillation is synchronous at point(s)

For equilateral spacing of conductors of an untransposed $$3$$-phase line, we have

The per unit voltages of two synchronous machines connected through a lossless line are $$0.95\,\angle {10^ \circ }$$ and $$1.0\,\angle {0^ \circ }.$$ Match the two sides in the following
