Temperature-dependent power curve

Understanding the temperature-dependent power curve issue

What is the purpose of the turbine issue check?

  • This is not a design feature, but instead a change in aerodynamic performance of the blades with temperature. Many turbines have built-in features to boost power below a certain temperature and if not operating as expected it can reduce the potential AEP of the turbine.
  • WindESCo will detect this behavior, determine if a compensation technique exists and tune those parameters to recover lost energy.

What does this look like?

  • For a given turbine, the power curve varies significantly with the ambient temperature.

  • Whereas a site with negligible performance difference between temperature changes:
