Transient Stability Analysis of Industrial Plant

Abstract

Industrial power system, Transient stability analysis is done to ensure the stable synchronized operating of
industrial systems experiencing sever fault, unaccepted load variation or heavy systems disturbance. In industrial power
system, instabilities are normally occurred due to faults.3 Phase fault are more severe than single fault or ground fault.
Transient stability analysis is performed by simulating post fault behavior generator after three phase fault. In this
paper, Transient stability analysis of industrial plants is presented using Electrical Transient Analysis Program -
7.5.5(ETAP). Here, power is produced by two generator of rating 16.5 MW, 11.8 MW and one generator keeping in
spares. Transient stability analysis is performed with both machines and with and without grid support of 22Kv. By this
analysis it is observed that phase angle oscillations of both the machines are far below than synchronization limit.
