When the interconnector between two stations has large reactance?
Correct answer: C. the stations will fall out of step be¬cause of large angular displacement between the stations
- A. the transfer of power will take place with voltage fluctuation and noise
- B. the transfer of power will take place with least loss
- C. the stations will fall out of step be¬cause of large angular displacement between the stations
- D. none of the above
Explanation
For a given transferred power, a large interconnector reactance requires a larger power-angle difference. This reduces synchronizing and steady-state stability, increasing the risk that the stations will fall out of step.
