BREAKING NEWS!! Power Cut affecting Railways in the South East

Catlow writes Strictly speaking Dinorwig was not designed as a backup generator, nor is used as one, as it is powered from pumped hydro storage and thus has a finite time from which it can provide useful energy conversion before the head of water becomes exhausted. These are all characteristics of a UPS. I'm not sure how important it is to make a distinction between: Generating capacity failing to cope because a power plant has tripped and Generating capacity failing to cope because demand has step- function increased. The first is very much a "backup", but the second (without an identical extra source of supply) would have caused the grid to fail. Over to you. -- "now, the thing you type on and the window you stare out of are the same thing" |

writes Strictly speaking Dinorwig was not designed as a backup generator, It would also be slightly difficult to claim that any such scheme is a generator, because it consumes more electricity than it generates (unless there has been a change in the laws of physics since I studied the things). Sometimes it generates, sometimes it soaks power up. Just like a UPS. -- "now, the thing you type on and the window you stare out of are the same thing" |
