AB  - The determination of the stability of a power system is
a crucial step in the power system analysis. The objective of this
study is to understand and investigate the transient stability of
IEEE 9-bus system that consists of three generators and nine buses.
For this, load flow analysis is firstly performed to determine the
pre-fault condition in the system. Fast fault clearing time and load
switching is then analysed to determine the system stability. For
the transient stability analysis, Euler and Runga method are
compared and variations in rotor angle and frequency of the system
under different fault conditions are analysed. The simulations are
done on Power Word Simulator Software. It is concluded that
power system should have very low critical clearing time to
operate the relays if faulty section is isolate within very short time,
thus, the system can obtain the stability otherwise it will go out of
synchronism.
