The Western HVDC Link

Alan Capon over 5 years ago

I did originally answer the previous thread, but have since deleted my response and I believe a new thread with a proper and correct title is the correct way of answering.

More info on the fault here: https://www.energy-reporters.com/transmission/italys-prysmian-under-fire-over-uk-interconnector-failure/

Reports suggest an undersea cable fault in the vicinity of Liverpool Bay.

Regards,

Alan.

OK, probably a silly question, but it's been nagging me. Why is the link d.c.? I can see the point when the two ends connect to two different grids that aren't synchronised (e.g. the UK and mainland Europe) but in this case it's just connecting Scotland with North Wales - so surely both ends are on the same grid and so naturally in sync with each other. In this case wouldn't an a.c. system have saved a lot of conversion at both ends?
