Failed temperature sensor

Understanding the failed temperature sensor issue

What is the purpose of the turbine issue check?

  • The ambient temperature sensor on a given turbine appears to have failed and is providing unreliable ambient temperature measurements.
  • 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?

  • Comparing the temperature sensor output - in the example below 3 temperature sensors are generating anomalous readings compared to their peers
