Integrating structural health monitoring into life-cycle management strategies for wind turbines can help owners and operators to accurately schedule maintenance and repair work at minimum associated life-cycle costs. Continuously updated monitoring data (i.e. structural, environmental, and operational data) can effectively be used to capture the operational and structural behavior of wind turbines and to reduce uncertainty in load and resistance parameters. However, permanently operating monitoring systems generate massive volumes of monitoring data that need to be organized, stored, processed, and analyzed in order to extract meaningful information. In this paper, a cyberinfrastructure framework for integrated structural health monitoring and life-cycle management of wind turbines is proposed. The secure framework is designed for scalable storage of large volumes of monitoring data and for online life-cycle management of wind turbines. This paper describes the overall architecture and the components of the cyberinfrastructure framework, which has been deployed in continuous monitoring of a 500 kW wind turbine for more than three years. Using the cyberinfrastructure framework, case studies are presented investigating the long-term structural performance and the operational efficiency of the wind turbine.
