Advantages of HVDC transmission over AC system is / are____________?
Correct answer: D. All of these
- A. Reversal of power can be controlled by firing angle
- B. Very good dynamic behavior
- C. They can link two AC system operating unsynchronized
- D. All of these
Explanation
HVDC links allow controlled power reversal, offer good dynamic control, and can connect AC networks that are not synchronized. Therefore, all three listed advantages apply.
