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
