Real Time Simulation of IEEE 9 Bus System for Fault Analysis Using Transient Response

Abstract

Power system stability is an important aspect of secure and economic power system operation. During designing and planning of the project, power system studies plays important role. This paper covers the real time simulation/ modelling of the IEEE 9 bus system using RT lab tools. In this, the fault is created on different locations in the multi machine system in running condition and transient stability is analyzed for different load and generating conditions in real time. Rotor load angle is a reliable indicator to identify the uncertainty in the system. So change in rotor angle of machines in the system is used as indicator of the transient stability of the system and to calculate the measures taken to maintain frequency and system stability. In this way fault have applied at different location in IEEE 9 bus system and the real time response have fetched with the help of OP 4510 simulator.
