| Summary: | Transient stability analysis plays an important role
for planning, designing and upgrading an existing electrical
power system network. In this paper, transient stability
analysis is carried out by considering a three-phase fault at the
busbars 7 and 4 with the effect of various fault-clearing times.
The simulation is carried out using CYME 5.02 power system
software with fast decoupled method. It is found that at fault
clearing times of 0.05s, 0.1s, and 0.15s, the generators (G2, G3)
under test are stable with respect to the simulation time.
Whereas, at fault clearing times of 0.2s and 0.3s, these
generators are found to be unstable for both faulted busbars 7
and 4. These simulation results are then compared with the
proposed model results and are found to be in good agreement.
In addition, it has been demonstrated that the transient
stability of a system can be improved using control devices. |
