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:
