Field station Frøya

Valsneset

We conduct full scale experimentation on wind and wind turbines out in the field on field station Frøya.

Facilities:

  • The VIVA Wind Turbine Test Site at Valsneset, Bjugn
  • The NTNU Wind Measurement Station at Titran, Frøya. Two 100-meter + one 45-meter Met-mast at the Skipheia measuring station + one 45-meter mast at the Sletningen islet.

Equipment:

Experimentation on:

  • Efficiency of 3 MW Wind Turbines
  • Wind characteristics e.g. duration and spatial size of Wind Gusts

Power and Efficiency versus equivalent wind speed

Case: big storm "Ivar"

The big storm "Ivar" visited Valsneset in Dec 2013. Blue curves give 10-min averages measured at 11 heights using a LiDAR. Red curves give max speed within each 10-min interval.

Probability Distribution Function

Measured wind speed on the absissa, and probability on the ordinate, with curve-fit using the Weibull distribution.
