Abstract
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.
