Special Issue Information

Dear Colleagues,

With the continuous global growth in demand for clean energy, wind power generation, as a significant form of renewable energy generation, has been widely adopted. Wind turbine generators are typically installed in either terrestrial or marine environments. During long-term operation, due to the complex and harsh environments they are exposed to, various components of the units are prone to wear, fatigue, and other faults. In particular, the drive train system, as a critical link in energy transfer within wind turbine generators, directly impacts the units' power generation efficiency, operational reliability, and service life. Therefore, conducting research on the health condition monitoring and intelligent operation and maintenance (O&M) of wind turbine generators is of great significance for ensuring the stable operation of wind power generation systems, reducing O&M costs, and improving energy utilization efficiency.

This Special Issue focuses on the health condition monitoring and intelligent O&M of wind turbine generators. It aims to gather the latest research findings and advancements in relevant fields both domestically and internationally, facilitate academic exchanges, and promote the development and application of intelligent O&M technologies for wind turbines. The topics of interest for this Special Issue include, but are not limited to, the following:

  • Intelligent sensing technologies;
  • Advanced signal processing algorithms;
  • Dynamic modeling and fault simulation of key components;
  • Fault warning and identification of key components in wind turbine generators;
  • Remaining useful life prediction based on deep learning;
  • Digital twin-driven fault diagnosis of wind turbines;
  • Knowledge graph and large-model technologies;
  • Research on O&M technologies and modes for offshore wind power in deep and far sea areas;
  • Predictive maintenance strategies for wind turbine generators.

This review systematically examines the evolution of maintenance strategies for complex systems, with a focus on the advancements in condition-based maintenance (CBM) decision-making methodologies. Traditional approaches, such as post-failure maintenance and time-based maintenance, are increasingly supplanted by CBM due to challenges like high costs or inefficiency in resource allocation. CBM leverages system reliability models in conjunction with component degradation data to dynamically establish maintenance thresholds, optimizing resource utilization while minimizing operational risks and repair costs. Research has expanded from single-component degradation systems to multi-component systems, leveraging degradation models and optimization algorithms to propose strategies addressing multi-level control limits, economic dependencies, and task constraints. Recent studies emphasize multi-component interactions, incorporating structural influences, imperfect repairs, and economic correlations into maintenance planning. Despite progress, challenges persist in modeling coupled degradation mechanisms and coordinating maintenance decisions for interdependent components. Future research directions should encompass adaptive learning strategies for dynamic degradation processes, such as those employed in intelligent agents for real-time environmental adaptation, and the incorporation of intelligent predictive technologies to enhance system performance and resource utilization.
