Performance Evaluation and Improvement in Transient Instability of IEEE 9 Bus System Using Exciter and Governor Control

摘要

In the contemporary world, especially developing countries, the demand for electricity is proliferating continuously and power is not only a criterion for fulfilling the requirement, but it is also the responsibility of engineers to provide the reliable and stable power to the consumers in a satisfactory manner. This paper discusses about the designing and improvement in “Transient Stability of IEEE 9 Bus Test System” using Power World Simulator. The simulation work explain the transients inthe system due to a fault which is an evaluated of the voltage stability, Rotor angle stability, frequency stability, Active power and reactive power. The simulation is done using a GNCLS model in which synchronous machine is represented using classical modelling [3]. This paper used exciter (AC7B) and PSS with AVR for improving transient instability.
