Question 55
EENAT2 marksNeeds review
The figure shows the single line diagram of a power system with a double circuit transmission line. The expression for electrical power is
, where
is the rotor angle. The system is operating at the stable equilibrium point with mechanical power equal to 1 pu. If one of the transmission line circuits is removed, the maximum value of
, as the rotor swings, is 1.221 radian. If the expression for electrical power with one transmission line circuit removed is
, the value of
, in pu is ________. (Give the answer up to three decimal places.)
