Answer / raghavendran.r

rotor angle or load angle stability denotes the angular
displacement between stator and rotor speeds.It is directly
proportional to the speed of the m/c ie the load connected
to the Generator.If the Angle is beyong tolerable limit,
the system will come out of synchronism.

Answer / s.ferna

The ability of synchronous machines of a power system to
remain in synchronism.
Stability phenomena
*Existence of equilibrium between Tm and Te under steady
state condition.
*Upset of the equilibrium, if the system is perturbed.
