Major use of HVDC(High voltage Direct Currrent) system is
employed in following situations.
1)When bulk amount of power is needed to transfer for a
distance greater than 800km,HVDC proves economical inspite
of establishing costly convertes/Invertes.In India,
majority of generations are located in eastern region while
majority of load centres are in western region.
2)Connecting two grid asynchronously by HVDC link.This is
called back to back connection.Such connection makes the
grid more stable as the stability problem of one region not
spread into other region.
