Im not formally trained in electrical engineering but have recently been forced in the last 6 months or so to get up to speed on many elec eng power type subjects. One of which is AC versus DC. I understand the history/science of it and why AC eventually won out. However, one story I encountered some months ago was the large electrical technology company ABB being awarded the contract to build a large DC line from mainland Europe to the UK. After all of my reading this story struck me as odd (based on what little I knew). Anyone have any insight/reasons why a large project like this would be designed in DC and not AC? Also, are there in fact cases where a DC system is more applicable/appropriate than an AC system, on a large scale anyway? One reason I thought of was that since its electricity being generated on one grid and being sent to another, packaging it as DC would be akin to just wrapping up a 'product' and shipping it off and then not having to worry about as much from the supplier's side. But Im not sure. This is a massive mult million euro project so Im sure there exists a good reason. Just curious to know how it might tie in with the AC versus DC argument.
