3. Fault diagnosis methods for wind turbines
The model built by internal or external diagnostic methods estimates or supervises the parameters or dynamics (operating modes/behaviors) that will be impacted by the consequences of fault occurrence. In general, these methods perform diagnostics by: 1) performance monitoring/analysis (power generated), 2) thermal monitoring/analysis (temperature) and 3) vibration monitoring/analysis (slow and fast shaft speed, 3-blade angles).
3.1 Diagnostics from power monitoring/analysis
The occurrence of a fault in a wind turbine, or one of its components, has an impact on its energy performance, characterized by the power generated P. This is why all model-based methods seek to estimate the power generated as a function of several contextual variables (wind speed, wind...
