Why was HVDC Kingsnorth ( https://en.wikipedia.org/wiki/HVDC_Kingsnorth ) shut-down only 13 years of operation? Why were the used mercury arc valves not replaced by thyristors?

Hallo,
Ik heb ooit Electro gedaan op de MTS,maar nooit iets geweten over HV DC lijnen,alleen electronica , installatie techniek en electrische machines.
Via het Wikipedia verhaal over de Engelse HV lijn in Devon ,kwam ik op een algemeen verhaal over HV DC lijnen uit.
Heel leerzaam ,ook het verhaal over hoogspannins DC lijnen ,hun geschiedenis en technieken. :grin:

Groeten ,
Peter

It says in the wikipedia article:
"The system described was shut down in 1986[2] or 1987[3] following system reinforcement on the network it was embedded in."
So in short the AC-network in the region was upgraded and could now carry the additional 600MW which went through the HVDC-link. This eliminated the need for a separate link and thus also reduce3d grid losses. I suspect also the older technology (mercury valves) has something to do with it as well.
