Question 1
The figure shows the single line diagram of a power system with a double circuit transmission line.
The expression for electrical power is 1.5 sinδ, where δ 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 δ, as the rotor swings is 1.221 radian. If the expression for electrical power with one transmission line circuit removed is Pmax sinδ, the value of Pmax, in pu
is ________.
