 The demand for wind energy has grown exponentially over the past few decades, leading to increased interest in developing more advanced wind turbines and improving their reliability and maintenance costs. Condition monitoring, CM, techniques offer an effective way to reduce ONM costs and increase reliability by providing real-time data about the health of the turbine. This paper reviews current trends in wind turbine condition monitoring, WTCM, including diagnosis and maintenance analysis, and discusses how these techniques can be applied to address the challenges facing the industry as it grows. The paper also identifies areas where further research is needed to ensure continued success in the wind energy sector.
