Power step and the equal-area criterion
A step in mechanical power, the swing it produces, and the equal-area criterion that predicts whether the machine stays in synchronism.

What to try
- Apply a small step and watch the rotor oscillate around a new equilibrium
- Increase the step until the accelerating area can no longer be matched, and the machine loses synchronism
- Relate the areas on the power-angle curve to the swing in the time trace
