An offshore one would be nice.


So there are, well spotted!
I'll have to work out a cheat sheet, RPM vs Tip speed.
Interesting, beta n all that maybe? I've just noticed that the rpm is sticking at under 15rpm even though wind is stated as 11mph, at 10.4rpm we were seeing 10mph. Blade angle has went up to 3degs from zero. Made me think maybe that's a little bit of throttling in action.

By the way, I think the live wind speed is shown in the wrong units, I'm pretty sure its showing m/s and not miles per hour as it seems to be consistently much lower than the average wind speed graph (which I believe to be correct in mph) and identical to the benchmark wind farm which quotes m/s.
1 m/s = 2.24 mph

https://www.vensys.de/fileadmin/user_up ... -2.5MW.pdf
Power Curve
Rated power 2.5 MW
Cut-in wind speed 3 m/s
Cut-out wind speed 25 m/s
Diameter 99.8 m - Therefore swept circumference is 313.5 metres.
Rated speed 14.5 rpm
I calculated a rotor tip speed table
