Transcribed Image Text:
A 60-Hz synchronous generator having inertia constant H = 5 MJ/MVA and X'd = 0.3 pu is connected to an infinite bus through a double circuit transmission line with the per unit reactances shown below. The generator is delivering P = 0.8 pu and Q = 0.074 pu to the infinite bus having a voltage of 1 pu. A temporary 3-phase fault occurs at the sending end of the line at point "F". When the fault is cleared, both lines are intact. If the fastest fault clearance time is 0.3sec, show that the system loses stability and then what would be your proposed solution (explain and calculate the values) to ensure system stability without installation of a new equipment? Hint: Solution is in the generator control. * Note: all depicted values are in per unit on the common system base, and all resistances are neglected. Xt = 0.2 E 03 उह X'd = 0.3 10x F XL1 = 0.3 XL2 = 0.3 2 V = 1.0 ∞ A 60-Hz synchronous generator having inertia constant H = 5 MJ/MVA and X'd = 0.3 pu is connected to an infinite bus through a double circuit transmission line with the per unit reactances shown below.
