In a power system, which of the following is/are critical clearance time of a fault related to?
1.
Transient reactance
2.
Sub-transient reactance
3.
Reactive power limit
4.
Transient stability limit
1 and 2
2
only
3 and 4
4
only
4
only
For
a fault in a power system, the term critical clearing time is related to
transient stability limit.
Critical
clearing time and angle are computed from equal area criterion, which is used
in transient stability study.
Hence,
the correct option is (D).
