We're on the Leicester line at the moment, and there are a number of very large wind turbines that have appeared fairly recently near Yelvertoft.
Cruising today, with little breeze to speak of (shame really cos it was very hot) we noticed they were turning, but so slowly one had to study closely to discern movement.
Surely moving that slowly cannot generate much electricity, or are they geared in such a way that any movement produces?
Figured you electrickery experts would know.
Thanks,
Rog

Modern turbine use power converters a bit like a travelpower box, such that the frequency (rotational speed) of the power source is not important - even if going slowly, some power is generated. But of course more power is generated when it's windy / turbines spinning faster.

Thank you.
Just been outside and noticed they are turning at a reasonable speed now, as thankfully there is some breeze.
And of course, they will continue to provide power overnight, which solar panels cannot.

The National Grid can't afford to switch on the extra power stations to make them turn in windy conditions. |

The National Grid can't afford to switch on the extra power stations to make them turn in windy conditions. I thought they used diesel engines to start them rotating eta I was surprised when told this (about the farm off the river Blackwater) I was told that the maintenance vessels regularly check the supply and re-fuel as necessary, I have never been able to confirm this (maybe should say never bothered) I know some of the earlier types needed to be brought up to speed before they would "synch" and start generating but I had always thought they would steal power from the grid to do so. |
