Glossary > Wind Turbine Maintenance
By maintaining wind turbines effectively, industry professionals play a vital role in the sustainable and clean energy revolution, ensuring a consistent source of renewable power for generations to come.
What is Wind Turbine Maintenance?
Wind turbine maintenance is a critical aspect of ensuring the efficiency and longevity of wind energy installations. For professionals within the wind turbine industry, this process involves a comprehensive set of activities aimed at keeping turbines in optimal working condition, especially as turbines are frequently exposed to extreme weather conditions that further contribute to wear and tear.
Below are some of the key challenges and strategies for cost-effective maintenance.
Once a wind farm is built, it must maintain critical components to maximize output and extend longevity.
The core components of a wind turbine that require frequent maintenance are:
- The turbine blades
- The nacelle
- The hub
Additionally, onshore towers house computer controls and power cables that require inspection and maintenance. Offshore towers are similar but have more complex foundations to add to the inspection list.
Common Wind Turbine Maintenance Issues
What are the most common maintenance issues wind farms face?
- Manufacturing defects
- Process control
- Loosening of parts
Many of the above issues can be kept in check with routine inspections and maintenance. Technicians and engineers will be able to know when simple maintenance can prevent issues or when it’s time to call in the OEMs.
Environmental causes can also be mitigated by adopting leading-edge maintenance strategies that use the right tools and systems, like vHive’s digital twin and drone inspection software.
Challenges with Conducting Wind Turbine Maintenance
All equipment requires inspections and maintenance, but wind turbines present unique challenges to stay aware of, including:
- Wind farms can be in remote locations or spread out over a large land holding or offshore
- Lack of appropriate data to predict maintenance
- Not enough personnel with the training necessary to conduct maintenance
- Needing to respond to unexpected downtime and unscheduled maintenance
- Inspections and maintenance become too costly, often due to poor inspection processes and maintenance scheduling
- Inspection of turbines often carry safety hazards associated with climbing
Overcoming these challenges is crucial to the successful operation of a wind farm, and it involves using the right strategies and tools to manage wind turbine maintenance costs. This means effectively catching potential issues before they escalate and cause more expensive problems.
Key Wind Turbine Maintenance Strategies
There are several strategies for wind turbine maintenance, many of which leverage leading-edge solutions that enable rapid inspections or generate more data to drive maintenance decisions. Let’s explore the core maintenance strategies and how they can enhance maintenance for your operation.
1. Predictive Maintenance
One of the most effective strategies is predictive maintenance, which has higher wind turbine maintenance requirements to adopt and enact. This strategy helps prevent breakdowns by leveraging data analytics, IoT and AI to predict problems before they occur.
You’ll need to use the right tools to benefit from predictive maintenance, such as digital twins, rapid autonomous drone inspections, and IoT devices. From there, the right solution can analyze a wealth of data to determine when maintenance will likely need to be performed.
2. Preventative Maintenance
This maintenance strategy is a time-honored method of scheduling routine inspections, and the replacement of critical components like bearings, gearboxes, and blades before they fail. This proactive approach minimizes costly downtime and repairs.
Since wind turbine blades are highly susceptible to wear and damage, this strategy calls for skilled technicians to perform regular cleaning, surface coating, or even replacement to maintain optimal aerodynamic performance.
3. Unplanned or Corrective Maintenance
When an issue already occurs, corrective maintenance is crucial. Teams are tasked with diagnosing problems and conducting repairs promptly to minimize production losses. This often includes fixing electrical, mechanical, or structural components. From there, technicians can ascertain what needs to be repaired to return the turbine to ideal performance.
As advancements in wind turbine maintenance and inspection technology continue to emerge, wind farm owners and maintenance stakeholders implement automated inspection technology such as vHive’s autonomous drone inspection technology and Digital Twin analytics, to enhance their turbines’ efficiency, reliability, and energy production.
