Benefits of HVDC transmission

Benefits of HVDC VSC technology



HVDC technology at transnational electrical interconnections

Energy exchange between two countries possible.

Lower investment costs due to smaller number of

conductors and simpler structures, no filters.

Connection of unsynchronized grids possible.

Continuously reactive power regulation.

Black start capability for Spanish or French power

grid possible.

Power reversal possible in 150 ms.

Benefits:



HVDC technology doubles energy exchange between France and Spain

The Siemens HVDC system which has been employed at the power link between France and Spain

is recently the most powerful HVDC transmission system worldwide based on voltage sourced converter

technology,

doubles capacity for exchanging electrical power between the two countries,

connects the Iberian peninsula with the European power grid,

increases the reliability of power supply and ensures that additional renewable energy sources can be

integrated without endangering the stability of the grid,

is an excellent model and a forward-looking approach which shows how bottlenecks in the transmission

grids throughout Europe can gradually be eliminated and

is a milestone on the road towards a single European energy market.
