The primary purpose of the project is to development a novel wind turbine maintenance strategy by combining condition based monitoring (CBM) and prognostics and health management (PHM) methodologies.

The wind turbines and wind turbine complex become larger in order to ensure the economic benefit. A large wind turbine with a high tower and long turbine blades may result in more severe mechanical and electrical load. As a result, the failure rate and operation rate of the wind turbine can be deteriorated. Especially, this problem can be more serious for offshore wind turbines which are beneficial for building a larger complex. Therefore it is essential to develop a totally different maintenance strategy to solve the above issues. This project focuses on: (a) the study of maintenance algorithm based on condition based monitoring (CMB) and prognostics and health management (PHM); and (b) the development of dependable embedded control system for wind turbine in collaboration with OPTIMUS project which is supported by EU-FP7-Energy program. The detailed research topics are as follow:
- To design a dependable embedded control system for wind turbines;
- To design a maintenance algorithm using combined CBM-PHM methods;
- Evaluation and verification of the result with a wind turbine simulator.

The core research contributions in this project include the followings: (i) to be used in various ways to enhance the reliability and cost-effectiveness of wind turbines; (ii) to obtain a fundamental technology for effective maintenance of wind turbines; and (iii) to establish a research infrastructure for developing advanced maintenance strategies for wind trubines. Also, a series of operating data and fault-related documents obtained through this project can be used to develop a predictive maintenance system and a reconfigurable control system for wind turbines. The research outcome in dependable embedded control can be used for commercialization of the wind turbine monitoring and control systems. The research outcome can also be widely applied to various fault-tolerant control systems including automobiles, automated systems, and weapon systems. The time synchronization techniques can be used for developing time-triggered communication networks and network-based control for many industrial applications. The resulting prognostics techniques can also be used for supporting monitoring of various industrial systems.
