Transient Stability AnalysLs ofthe IEEE 9-Hus Electric Power System

Abstract

It k widel>' accepted that transient stablity Ls an inportant aspect in designing and upgrading electric power system. TTik papercovers the modelling and the transient stability analysis ofthe IEEE 9 bus test system ushg ETAP. In thK. for various fauks on the test system fast faul clearing and load shed are analysed to briig back the system to the stability. Frequency k a refobie indicator if deficiency condition in the power system exlsts ornoL Change h power demand orin pnoduction causes a łlictuation ofthe speed of the turbinę-generator conditbn exi>ts on the power system, resulting in łluctuation of the frequency of the power system. So ratę of change of frequency Ls used as iidicator 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 fiequency of the system
