The project has produced a standard training course based in a MOODLE platform where all the contents are integrated as well as the different digital tools below presented. The purpose of the consortium is to promote the use of either the course as a whole or some independent modules or tools, serving always as practical basis of the theoretical teaching.

The course provides the training contents of the wind turbine technology (WTG) including the descriptions of the different components of a WTG and their function. It also deals with the maintenance of WTG and Wind Farms (WF) from both, general and specific point of view, as well as the main tasks for either extending the life of repowering the WF installations.

The contents and outcomes of the project are very practical. They are related to:
- Faults types and trees to evaluate the root causes
- Maintenance typologies and procedures
- Procedures to extend the life of the assets
- Repowering, recycling & reuse of components and materials
- Health, Safety and Environment
- Principal metrics used in the sector
- Typical contractual arrangements

In order to get an initial overview of the operation and maintenance market, all partners have written a summary that also explicitly addresses the situation in the partner countries. The document gives a very good overview and is filled with the latest market figures.
This document is written by 8.2
Evaluation of the operation and maintenance market

In this first video you can explore the virtualized model of a wind turbine.

With the help of the following vidoes, the students can learn the solutions of the various tasks. After doing this, the students can play through the scenarios themselves in the virtual environment. During the performance, the student can always get help via his virtual tablet if he does not know what to do at a point in the task. Further useful information on the respective steps can also be stored on the virtual tablet.

This WP developed the Section 1 of the Moodle: Introduction to wind turbine technology. This section provides an overview of the different components of a wind turbine, their function and how they fit together as an operational power generation machine.

Digital Tools

WExLaB: This software integrates OpenFAST source code with a standalone MATLAB application as a graphical user interface. There are four parts of software:
- System level analysis
- Modal analysis
- Load analysis
- Operation and control of the wind turbine

In the WEXLab area, students are introduced to the basic relationship between wind turbine design, output and costs. In addition to theoretical basics, students can also apply their knowledge in various small Matlab Simulink programs. For example, TU Delft has developed a program that demonstrates to students the relationship between LCOE (levelized cost of energy) and basic wind turbine design (rated power and blade length).
This part of the training material will allow students to gain a basic understanding of how a wind turbine is designed and operated, including a description of the basic components. The students will should an appreciation of how the components function as a system and how wind turbines are connected to the grid in the form of a wind farm including aspects of layout optimisation, e.g. minimisation of wake losses.

This application analyzes the wind turbine at the system level. Using this application, you can calculate the power curve, CAPEX and OPEX cost, LCOE, and capacity factor of the wind turbine. You can also see the effect of blade length on the capacity factor and LCOE.

This application can be used for modal analysis of the wind turbine. Using this application, you can calculate the natural frequencies of the blade or tower and plot the Campbell diagram.

This application calculates the loads on the 5 MW NREL wind turbine. Using this application, you can calculate the aerodynamic and operational loads on the 5 MW NREL wind turbine blade. The effects of pitch and yaw angle on the aerodynamic loads can also be seen.

This application analyses the performance of the 5 MW NREL wind turbine. Using this application, you can see the overall performance of the 5 MW NREL wind turbine. You can calculate the operation parameters such as pitch angle, torque, power, tip deflection, etc. These operation parameters are calculated in the case of either a healthy or a faulty pitch system.

The following documents are written by TU Delft and give additional information for this module:

Wind turbine diagrams

CaDWEx (Cascade Damage Explorer) is a software that allows the students to explore the chains of damage of a specified component in the area of fault tree analysis. Each chain of damage is a time ordered list of damages that afect a component, as a damage evolves over the time and creates different damage. And as example, CaDWEx focusses on the gearbox.
All possible faults of the wind turbine gearbox were analysed and listed with the help of experts. The experts also indicated the previous and subsequent faults for each individual fault, this is, the pasts damages that could causes the present damange, and the future damages that the present damage can cause .
The software takes this informations and builds the chains of degradation from a specified fault (damage). To do that, converts the information on numbers and builds the chains by comparison as it can be observed in the slides below, so a complete fault tree can be created by the student.
Using this fault tree, the students can now learn about the faults, and how the individual faults develop in the gearbox of a wind turbine along time. The learning material also shows the student when and how to react correctly to the respective faults.
The software easily adapts, and with little modifications, to other components if the information of the fault development is provided by experts on the components.

This WP developed the Section 2 of the Moodle: Maintenance students can learn about the different maintenance procedures, the main specifics of offshore maintenance as well as some general concepts about contractual models and asset management.

Digital Tools

The following video is about WExViR and it was made by UTEC for the Section 1: Introduction to Wind Turbine Technology.
Through the WExViR digital tool, the theoretical concepts can be assimilated with virtual tours through a wind turbine with 360 ° images using the H5P tool.

In the area of WinEXVir, the theory of the various maintenance variants (preventive, predictive and corrective) with virtual tours and branching scenarios is combined with the H5P tool. The various maintenance approaches have been developed and summarized in detail by UCLM. Students learn the different approaches, the differences in approaches and the practical measures involved. In addition, DP2i has created a complete fault tree for the gearbox of a wind turbine, which students can use to learn how damages develop in gearboxes.
The virtual tours in H5P were created by 8.2 and DP2i. The basis is a Senvion 3XM wind turbine, which have visited 8.2 and RSC. On the right side you have an example of H5P. Students can walk through the wind turbine and view the corresponding tasks on each component.
The theoretical and practical part is integrated into our Moodle platform. For the theoretical part of the maintenance strategies, there are appropriate documents for the students to learn the basics. In the virtual tour, this knowledge can then be deepened. On the Moodle platform, UCLM has developed the corresponding questionnaires, with the help of which the knowledge of the students can be queried at the end.
The theory of different maintenance strategies can be read in the following document written by UCLM.
Summary of Deliverable R5.1 types of Maintenance Strategies

This WP developed the Section 3 of the Moodle: Repowering and Life Extension. HSE Isues.
In section 3 the contents are presented through different training videos with the special function of interactivity. The development has been done with the collaboration of different educators and teachers.

The Moodle platform was created by UCY. In cooperation with the other project partners, the platform is filled with the content desrcibed above. There will be various courses on the platform.
A course contains theoretical learning material and the various digital learning tools. In addition, there will be corresponding questionnaires with the help of which the knowledge and thus the learning success of the students can be queried. Finally, there is a calendar and a forum where the students and the teacher can exchange ideas.
The platform can be continuously adapted and expanded.
