Technically, there is one main use case in our project: The Wind Turbine itself.
However, looking closer, one can identify a several subsystems where things can go wrong. Therefore, we take each of such subsystem as a use case.
In order to identify the most impactful of the use cases with the condition that handling them will be feasible within the project, we looked into potential failures of a number of subsystems, quantified their criticality by investigating severity and probability of each subsystem failure, then checked for data availability needed to support a data analytics study to effectively take place.
The consortium concluded that the following 10 use cases shall be handled during the rest of the project.
| Use Case ID | UC1 |
| Use Case Name | Generator system |
| Responsible | ISOTROL |
| Brief description | Detection of failures and underperformances in the generator, focusing on temperature and mechanical failures. |
| Use Case ID | UC2 |
| Use Case Name | Pitch system |
| Responsible | ISOTROL / TECNALIA |
| Brief description | Identify failures such as misalignment using data analytics (ISOTROL) and model analysis techniques (TECNALIA). |
| Use Case ID | UC3 |
| Use Case Name | Yaw system |
| Responsible | ISOTROL/TECNALIA |
| Brief description | Detection of failures such as misalignment or runaway misalignment using data analytics (ISOTROL) and model analysis techniques (TECNALIA). |
| Use Case ID | UC4 |
| Use Case Name | Gearbox system |
| Responsible | ISOTROL/ENFORMA |
| Brief description | Detection of issues (ISOTROL) and predictive analysis implementation (ISOTROL + ENFORMA), such as oil pressure or system temperature. If vibration data is available, a CMS analysis will be pursued (ISOTROL + ENFORMA), to identify rupture of gear teeth or their separation. |
| Use Case ID | UC5 |
| Use Case Name | Initial performance analysis |
| Responsible | ISOTROL |
| Brief description | Oversight of power curve deviations from optimal production and other significant analysis such as outliers. Power curve degradation over time will be included in the scope of the analysis. |
| Use Case ID | UC6 |
| Use Case Name | Blade system |
| Responsible | ENFORMA |
| Brief description | Analysing the causes of the asymmetrical situation at the blade angles, which points to the malfunctions related to the pitch system and resolving the problem without damaging the blade. |
| Use Case ID | UC7 |
| Use Case Name | Turbine shaft |
| Responsible | ENFORMA |
| Brief description | Analysis and modelling of fatigue, overheating and deformations in the turbine shaft, in the presence of vibration data. |
| Use Case ID | UC8 |
| Use Case Name | Converter and electrical systems |
| Responsible | ENFORMA |
| Brief description | Analysis of subsystems such as UPS, converters and identification and prediction of failures. |
| Use Case ID | UC9 |
| Use Case Name | O&M recommendation and actions |
| Responsible | ISOTROL |
| Brief description | Provision of the concrete maintenance actions to be performed and their scheduling to optimize the power output of the plant. Focus set on the generation of concrete action tickets. A proper visualization of the overall plant status will be implemented to ease the review of the plant overall performance to O&M operators. |
| Use Case ID | UC10 |
| Use Case Name | Advanced wind farm operation control / Wake effect reduction |
| Responsible | RUB |
| Brief description | Identification of wake formations and minimization of their effects on the total energy yield and mechanical loads using active wake control for the wind farm operation |
