The single line diagram of a lossless system is shown in the figure. The system is operating in steady-state at a stable equilibrium point with the power output of the generator being 
, where 
is the load angle and the mechanical power input is 
. A fault occurs on line 2 such that the power output of the generator is less than during the fault. After the fault is cleared by opening line 2 , the power output of the generator is 
. If the critical fault clearing angle is 
radians, the accelerating area on the power angle curve is ________times 
(rounded off to 2 decimal places).
Assume maximum power transferrable before the fault
Before fault the system is operating under steady state so 
After fault clearance,
Accelerating area = Decelerating area (by equal area criterion)
Decelerating Area
