A generator with constant 1 0 p u terminal voltage supplies power through a step up transformer of 0 12 p u reactance and a double circuit line to an infinite bus bar as shown in the figure The infinite bus voltage is maintained at 1 0 p u Neglecting the resistance and susceptances of the system the steady state stability power limit of the system is 6 25 pu If one of the double circuit is tripped the resulting steady state stability power limit in p u will be 1 2 X 3
