Advantages of HVDC Links
The Power Flow on an HVDC link is Fully Controllable - Fast and Accurate! The Operator or automatic controller determines how much power flows
via the link
An HVDC Link is asynchronous - the ac voltage and frequency in the two ac networks can be controlled independently of each other.
The HVDC link can be used to assist one (or even both) of the acnetworks (e.g. power system damping)
HVDC links do not increase the Short Circuit Level of the system
Faults dont transfer across HVDC interconnected systemsHVDC provides increased Transmission Capacity in a fixed corridor
Up to 3 times more power per tower
HVDC can transport energy economically and efficiently over longer distance than ac lines or cables.
Sometimes HVDC is the only option!

Why Use HVDC?
Connection of remote generation >800km
Submarine links >50km
Frequency conversion 50-60Hz
When synchronism of AC connections is impossible
