Consider
the following statements: Stability studies constitute
1.
The major analytical approach to the study of power system electro-mechanical
dynamic behaviour.
2.
The involvement of one or just a few machines undergoing slow or gradual
changes in operating conditions.
3.
The determination of the locus of essentially steady-state operating points of
the system.
4.
The determination of whether or not the rotors of the machines being perturbed,
return to the constant speed operation.
Which
of these statements the correct?
1,2 and 3
2,
3 and 4
1 and 4
1,2, 3 and 4
1 and 4
Stability
studies constitute :
The
major analytical approach to the study of power system electro-mechanical
dynamic behavior.
The
determination of whether or not the rotors of the machines being perturbed,
return to the constant speed operation.
Hence,
the correct option is (C).
