what are advantage and disadvantage of hvdc transmission .
please tell us technic of hvdc technology
Answer Posted / silu pattanayak
Also, following advantages;
1. no frequency mis-match problem and hence helps in Grid synchronization of two different Reason.
2. Better control over power flow by controlling the Load angle.
3. Easy transmission for long distance lines, as there is no Capacitive voltage increment ( due to Ferranti effect ).
Disadvantages:
More complicated and initial cost of the plant is many times higher than that for the terminal equipments of AC stations of same capacity.

Hi Suppose we have a wye/wye transformer which is grounded at both sides,in this situation, do we have ay ground transformer? in other words, ground transformer can do any thing more (while we have nuetral wire in both sides)? As the last question, what about 3rd harmonic? we have two choices: first using wye/delta transformer + ground transformer and second using wye/wye earthed connection.in the former choice, we dont have 3rd harmoonic at the secondary side but what about Yn/yn conection? do we suffer from 3rd harmonic in the Yn/yn connection?
