Step-by-step instructions for wind power: maintenance and care of wind turbines

Regular maintenance and care is crucial to maximise the service life and efficiency of your wind turbine. In this guide, you will learn how to check and maintain the most important components - from rotor blades to electrical connections

Why is maintenance important?

Efficiency: Regular inspections ensure maximum energy production.

Longevity: Timely repairs prevent damage and extend the service life of your system.

Safety: Maintenance minimises risks such as short circuits, loose parts or mechanical failures.

Maintenance steps in detail

1. inspection of the rotor blades

Visual inspection: Check the rotor blades for cracks, wear or dirt deposits.

Cleaning: Remove dust, ice or bird droppings to maintain aerodynamics and efficiency.

Bolts and connections: Check all rotor blade fastenings for strength.

Tip: Use a drone for areas that are difficult to access or hire specialists for large installations.

2. inspection of the mechanical parts

Gearbox: Check the oil level and the quality of the lubricating oil. Change the oil according to the manufacturer's recommendations

Bearings: Listen for unusual noises that could indicate worn bearings.

Vibrations: Measure vibrations on the tower and gearbox to detect irregularities.

Tip: Keep spare parts such as bearings and seals to hand so that repairs can be carried out quickly.

3. Checking the electrical components

Generator: Check the performance of the generator and look out for signs of overheating.

Inverter: Ensure that the inverter is working properly and does not display any error messages.

Cables and connections: Check all cables for damage, corrosion or loose connections.

Tip: Install a monitoring system that recognises and reports faults at an early stage.

4. Inspection of the tower and foundation

Stability: Check that the tower is stable and secure.

Corrosion: Check metallic parts for rust and treat them with protective agents.

Screws: Tighten all screws, especially after heavy storms or wind loads.

Foundation: Check the foundation for cracks or other damage that could affect stability.

5. maintenance intervals

Monthly: Visual inspection of the system and cleaning of the rotor blades.

Half-yearly: Check the mechanical and electrical components as well as the connecting elements.

Annually: Professional maintenance by experts, including thermographic analysis and sound measurements.

Frequent problems and solutions

Power loss:

Cause: Dirty rotor blades or defective cables.

Solution: Clean and repair the affected parts.

Noise or vibrations:

Cause: Worn bearings or loose connections.

Solution: Replace the bearings and tighten the screws.

Corrosion:

Cause: Weather influences on metal parts.

Solution: Regular treatment with rust inhibitors.

Safety measures

Protective equipment: Always wear a helmet, gloves and safety goggles when working on the system.

Switching off: Switch off the system completely before maintenance.

Proper execution: For complex maintenance work, commission qualified specialist personnel.

Conclusion: Efficiency and safety through regular maintenance

A well-maintained wind turbine not only provides reliable energy, but also minimises downtimes and costs. With these instructions, you can keep the condition of your system under control and ensure its long-term operation.
