Back in 2019, we finished an UG project creating a timeline of #HVDC projects 🌎🌍🌏 and also added the what was then the newly proposed πŸ‡¦πŸ‡ΊπŸ‡ΈπŸ‡¬ #suncable project.

This just looked at one aspect (the most technically challenging of all ⁉️) the undersea cable.

1/x I also wrote a (very short) article for the #VSC #HVDC newsletter that @OfficialUoM Prof. Mike Barnes was editing on the news coming out of Australia

Here are some figures that might help put the #suncable project in context.

OK, most of the following is textbook stuff on #HVDC but just a quick reference for what a "low-voltage metallic return" - the faulty part of #Basslink - is used. Basslink is a monopolar HVDC system and the original design was based on an earth return. This is quite typical of monopolar #HVDC systems as it reduces cost (requires only one cable) and losses (again because of one cable)

Reading through @OtherProfGreen summary of the 9th August #UK event, the similarities to the 25th August 2018 #Australian separation event across the #NEM are very interesting to observe. Firstly, they are all attributed to lightning strikes.

And although the #UK one was easy to identify, the #QLD one took a bit of forensic investigation as it happened at a time that no weather warnings were out for the area.
