DYNAMIC STABILITY ANALYSIS OF MULTIMACHINE SYSTEM WITH PARTICULAR REFERENCE TO BHAKRA NANGAL FERTILIZER FACTORY SYSTEM

Abstract

A rovier of the existing methods for analysing the dynamic and transient stability of pouor systems has been made. The mathematical models of the various compo-» nentn of the system required for analysis are outlined. The dynatiicdynamic stability of Bhakra-Nangal fertilizer factory system vrhon it is run isolated from the system using state apace method is analysed. Field observation indicated that the cystca is dynamical unstable and is also confirmed from the analysis presented here. To stabilize the system food back signalsin the AVR based on first and eocond derivatives of rotor angle are tried and their results presented. Higher order derivua tivoc of rotor angle are suggested.
