Lightning Protection: Wind turbine blades are designed to withstand lightning strikes, but lightning protection systems should be in place to minimize potential damage. These systems typically include lightning receptors, conductors, and grounding to divert lightning strikes away from critical components.
Repair and Maintenance: If any damage or issues are identified during inspections, appropriate repairs should be carried out promptly. This can involve repairing cracks, replacing damaged components, or addressing leading edge erosion. The manufacturer's guidelines and recommendations should be followed for proper repair procedures and the use of suitable materials.
Edge coating, also known as leading edge protection, is a common practice in wind power blade maintenance to protect the leading edge of wind turbine blades from erosion caused by environmental factors. The leading edge of the blades is exposed to various elements such as rain, sand, dust, and particles carried by the wind, which can cause wear and reduce the aerodynamic efficiency of the blades over time. Edge coating helps to mitigate this erosion and extend the lifespan of the blades.
Aerial Drones: Drones equipped with cameras and spraying systems can be used to inspect and clean wind turbine blades. They fly around the turbine, capturing images and videos of the blades to identify areas that require cleaning. They can also spray cleaning solutions or use brushes to remove debris from the blades' surfaces.
Sensors and equipment: The crawler is equipped with various sensors and equipment to inspect the internal condition of the blades. These may include cameras, infrared thermography devices, ultrasonic sensors, and others. They help detect damages, cracks, structural issues, or other potential defects within the blades.
