The main objective of this project is to outline a condition monitoring strategy which may reduce the impact of some hydraulic pitch system failure modes on the wind turbine´s design load cases, and based on that strategy, to develop and validate a digital platform for component/system diagnosis.
As a subsystem, the hydraulic pitch system is critical for the functionality of the wind turbine generator as it is the responsible for:
DOCC-OFF will identify the failure modes of the pitch system in order to select the key parameters to be monitored, and it will develop a digital platform that will capture and manage the operating data to detect and predict the identified failure modes in time. This will improve the operation and maintenance of the pitch system.
Digitalization of Critical Components in OFFshore wind turbines
Objective: to identify the failure modes of a pitch/hydraulic system and to develop data-based analytical solutions
1. Identification of specific condition monitoring opportunities within a typical hydraulic pitch system, via a failure mode effect and criticality analysis (FMECA).
2. Selection of the key parameters to be monitored in order to detect the identified failure modes in time, and development of a hybrid process where synthetic and real operation data are combined to obtain a representative data set and to improve the classification outputs of failure diagnosis.
3. Development of a digital platform that will capture and manage data from the monitored components, with the objective of reducing the impact of the identified hydraulic pitch system failure modes on the wind turbine’s design load cases.
WP2
Digital technologies
specification and development
WP2 will be devoted to identify otherwise critical failure modes on the hydraulic pitch subsystem which may be made non-critical (or whose criticality may be reduced) via condition monitoring, and to develop a digital platform which, applied in the subsystem, will help to reduce the impact on the wind turbine´s design load cases
WP3
Digital platform
validation and demonstration
WP3 aims to validate the systems developed in WP2 in a testing site and analyse the opportunities to demonstrate the full integrated solution.
