Transient stability analysis of Gadong Power Station

Transient stability analysis is very important to find the behavior of the synchronous machines under faulted condition. In this paper, IPSA simulation software is used to study the transient stability analysis of Gadong Power Station. Three-phase faults are considered at the busbar 1415LPS and 2829GPS1 with different fault clearing times. From the location at 1415LPS busbar, it is found that the generators of the Gadong I power station are stable for the fault clearing times of 0.1 s and 0.3 s and becomes unstable for the fault clearing time of 0.6 s and 0.7 s. At the other location of the busbar 2829GPS1, the generators of the Gadong I power station becomes unstable for the fault clearing time 0.7 s.
