Wind turbines have the third-largest power-generating capacity in the U.S. The increasing dependence on wind energy means that reliability is even more critical.
Proper maintenance is essential for wind turbine performance. A small wind turbine repair is better than a significant problem that leads to costly downtime.
Learn more about how to identify and prevent some common wind turbine issues.
The Importance of Wind Turbine Maintenance
Regular wind turbine maintenance can help you avoid the need for repairs. A visual inspection of the entire structure is the first step. The inspection includes:
- Blades
- Nacelle
- Tower
- Generator
Maintenance includes cleaning, lubrication, and minor repairs. The technicians usually clean the wind turbine manually. They remove any debris that may have accumulated.
Lubrication with grease or oil helps prevent wear and tear. In addition, it allows the turbine to perform its best.
Repairs can include replacing damaged parts. Blades, bearings, and gearboxes are common elements that may need repair. Unfortunately, these components are some of the most likely to fail.
Avoid Blade Failure
Problems with the rotor blades can lead to an expensive and lengthy downtime. Issues that can cause blade failure include:
- Adhesive joint failure
- Splitting along fibers
- Gel coat cracks
- Leading edge erosion
- Manufacturing defects like debonding
Recognizing these problems during regular maintenance gives you a chance to repair them. As a result, you can avoid more significant problems later.
Prevent Electrical Problems
Electrical problems in wind turbines are often a result of moisture. In addition, wind turbines face operating conditions, including wide temperature variations and extreme weather.
Outside air can bring moisture, salt, and other corrosive elements into the wind turbine system. Condensation forms inside the tower and nacelle. The water can collect inside the electrical components, leading to failure.
Humidity control and protection against moisture help prevent electrical problems. However, regular inspections for rust and corrosion are also necessary.
Keep the Generator Running
If the generator fails, the wind turbine can’t produce power. Generator failure can result from electrical or mechanical issues. Common problems include:
- Worn bearings
- Excessive vibration
- Irregular voltage
- Failure of the cooling system
- Contaminated lubricant
- Poor insulation
Inspections that focus on these areas can improve the performance and reliability of the generator.
Avoid Gearbox Failure
The gearbox must withstand harsh conditions and mechanical stress. The bearings and gears are responsible for most gearbox failures. Causes of these problems include:
- Improper settings for the bearings
- Contaminated lubricant
- Wide temperature fluctuations
- Sudden accelerations and load-zone reversals
Proper maintenance and repairs are especially critical for the gearbox. Replacing the gearbox takes at least a few days. If wind turbine spare parts aren’t available, the downtime can be much more extended.
Remember the Brakes
Wind turbine brakes are essential for the function and safety of the windmill. Therefore, the surface finish and track flatness are crucial. Slight imperfections can lead to poor performance.
Misalignment of the track can also reduce performance. A lack of traction can put the wind turbine at risk of damage or failure.
Proper maintenance is essential. Calipers and pads should be changed regularly; brake disc resurfacing can improve performance.
Use the Right Replacement Wind Turbine Parts
Proper maintenance can help you avoid expensive downtime in the wind farm. You can make a minor wind turbine repair instead of waiting for a significant problem to develop. The blades, generator, and gearbox are some wind turbine parts to focus on.
