Smarter blade feathering so can safely run through 85kph winds. Broke generation records. Neat! We need more of this.
It's a 16 MW turbine, and the record it set is 384.1 megawatt-hours over a 24-hour period. So... 16.004 MW average. Basically, topped out the whole time (thanks to that "smart blade adjustment", whatever exactly that is.)
I would imagine that the smart blade operates similar to set of rotors on a helicopter, increasing and decreasing pitch of the blade. If the wind is too powerful, the blade can rotate to reduce the efficacy of the rotor, saving the motor and downstream systems.
