Question
A synchronous generator is connected to an infinite bus with excitation voltage pu. The generator has a synchronous reactance of pu and is delivering real power () of pu to the bus. Assume the infinite bus voltage to be pu. Neglect stator resistance. The reactive power () in pu supplied by the generator to the bus under this condition is _________.
Correct answer
0.1 to 0.12
Solution
Given:
Excitation voltage pu
Synchronous reactance pu
Real power pu
Infinite bus voltage puReal power delivered is given by:
Now, Reactive power delivered is given by:
pu.
Excitation voltage pu
Synchronous reactance pu
Real power pu
Infinite bus voltage puReal power delivered is given by:
Now, Reactive power delivered is given by:
pu.
