Rated power temperature compensation non-functional

Understanding Rated power temperature compensation check

What is the purpose of the turbine issue check?

• A given turbine with rated power temperature compensation is operating differently than others of the same turbine model at a given site.
• Many turbines have built-in features to boost power below a certain temperature and, if not operating as expected, the increase in AEP will not be realized.

What does this look like / How do you identify this issue?

• Rated power distribution for temperatures >26 degrees C at this farm is consistent across the farm (> 15 m/s)

• Rated power distribution for temperatures <26 degrees C at this farm varies significantly (> 15 m/s)
  • Some turbines were not seeing a significant boost at all
  • This had a 0.3% AEP impact on the site operations
