AI Technical Summary

⚠Technical Problem

Wind turbine generators (WTGs) experience excessive vibrations, particularly when inactive, leading to potential damage and reduced operational lifetime, with existing vibration mitigation solutions having limitations in ease of deployment, suitability for different turbine components, or effectiveness across the full length of blades and towers.

⚗Method used

A method and system using a drone to deploy an airflow disruption line around parts of the WTG, such as a tower or blade, by securing it at attachment positions with minimal manual intervention, disrupting airflow to mitigate vibrations, using a lightweight and compressible line like a foam rope or inflatable hose.

🎯Benefits of technology

The method allows for rapid, safe, and cost-effective deployment and retrieval of the airflow disruption line, reducing vibrations and extending the WTG's lifespan by minimizing stress and fatigue on components, while avoiding entanglement with blade serrations.

Abstract

A method for mitigating vibrations on a wind turbine generator (100). The method includes providing a drone (10) carrying an airflow disruption line (6) on a spool (14), securing a first portion (8) of the airflow disruption line (6) at a first attachment position on the wind turbine generator (100), deploying the airflow disruption line (6) around at least one part of the wind turbine generator (100) by flying the drone (10) around the at least one part from the first attachment position to a second attachment position on the wind turbine generator (100), and securing a second portion (9) of the airflow disruption line (6) to the second attachment position. The method enables efficient installation and removal of vibration mitigation devices on wind turbine generators (100) same with minimal manual intervention, reducing downtime and maintenance costs while effectively mitigating various types of vibrations in wind turbine structures.
