A review of concepts and methods for wind turbines condition monitoring

As the demand for wind energy continues to grow at exponential rates, reducing operation and maintenance costs and increasing reliability is now a top priority. Aside from developing more advanced wind turbines designs to improve the availability, an effective way to achieve this improvement is to apply reliable and cost-effective condition monitoring techniques. This paper is a general review and classification of methods and techniques for wind turbine condition monitoring. After highlighting on condition monitoring, diagnosis and maintenance theories, it outlines the relationship between these theories and related technical concepts.
