1) HVDC Transmission<\/b> can operate with one conductor and ground as return path.on other hand AC transmission required 2 or more conductor, Hence conductor material saved.
\nEach conductor operate independently.<\/p>\n
2)DC power transmission is use for long distance<\/p>\n
3) two different DC grid ( same voltage) can be connected together because frequency of dc voltage is zero. We can not connected two grid with different frequencies in ac transmission without using dc link.<\/p>\n
4) skin effect is absent in DC transmission.<\/p>\n
5) In DC bulk power can be transfer<\/p>\n
6) No charging current needed in DC transmission for underground cable<\/p>\n
7) Power factor is unity hence reactive power compensation not required
\n
\n8) Power transfer per conductor is more<\/p>\n
9) simple construction<\/p>\n
10) Less corona loss<\/p>\n
11) Synchronous operation not required. Hence distance of transmission is not limited by power stability<\/p>\n
12) Single conductor with ground return can be compared with AC 3 phase single circuit line<\/p>\n
