Transient Stability Analysis of the IEEE 9-Bus Electric Power System

It is widely accepted that transient stability is an important aspect in designing and upgrading electric power system. This paper covers the modelling and the transient stability analysis of the IEEE 9 bus test system using ETAP. In this, for various faults on the test system fast fault clearing and load shed are analysed to bring back the system to the stability. Frequency is a reliable indicator if deficiency condition in the power system exists or not. Change in power demand or in production causes a fluctuation of the speed of the turbine-generator condition exists on the power system, resulting in fluctuation of the frequency of the power system. So rate of change of frequency is used as indicator of the transient stability of the system and to calculate the amount of load to be shed by adaptive load shedding and measures taken to maintain stability and frequency of the system.
