Field station Frøya

Department of Energy and Process Engineering

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.
