A huge power failure in the UK on 10 Aug 2019 cut power to trains, traffic lights and millions of people at home.
Two power plants caused the failure. The official report claims that the Little Barford gas-fired station in East Anglia failed first, then, 2 minutes later, an offshore wind farm (Hornsea) in the North Sea failed 2 minutes later.
This is a lie, says WUWT (WattsUpWithThat). The truth as revealed by detailed research by blogger is that the wind farm clearly failed first, and caused the whole event.
Like the captain of the Titanic aiming for a transatlantic speed record, the UK national grid were aiming for a record percentage of power from wind. They reduced the safety margin of grid inertia for this purpose, and the result was disaster:
11Aug 2019, “It doesn’t add up” (From the blogger referenced above.)
“I’ve done a lot of research on this, looking at the data from National Grid at BM Reports, Gridwatch, and a very helpful frequency chart at 1 second resolution from Upside Energy, a small company providing experimental token grid stabilisation services using distributed systems (a potential precursor to such things as V2G). You can see that their effort was very prompt but puny at under 6MW for about 3 minutes in this chart they tweeted.
“Here’s what I found:
I think the conclusive answer to the question is yes – the blackout’s primary cause was the sudden loss of output from Hornsea wind farm, though the precise cause of that remains unknown at this stage: likely candidates are a failure at the offshore transmission platform where the voltage is boosted to 220kV, somewhere along the cable to shore, or at the grid connection point (at Killingholme on the Humber) onshore. The really damning evidence comes in this tweet that shows grid frequency based on 1 second data.
The blogger continues with a technical discussion that you can read on WUWT.
“Do not be deceived by the reported outage times on the plants,” says the blogger.”
“I note that today the formal record of the timing of the shutdowns has magically disappeared. More questions to be answered.”
