Condition monitoring of spar‐type floating wind turbine drivetrain using statistical fault diagnosis
Ghane, Mahdi; Nejad, Amir Rasekhi; Blanke, Mogens; Gao, Zhen; Moan, Torgeir (Journal article, 2018)Operation and maintenance costs are significant for large‐scale wind turbines and particularly so for offshore. A well‐organized operation and maintenance strategy is vital to ensure the reliability, availability, and ... -
Diagnostic monitoring of drivetrain in a 5 MW spar-type floating wind turbine using Hilbert spectral analysis
Ghane, Mahdi; Nejad, Amir Rasekhi; Blanke, Mogens; Gao, Zhen; Moan, Torgeir (Journal article; Peer reviewed, 2017)The objective of this paper is to investigate the frequency-based fault detection of a 5MW spar-type floating wind turbine (WT) gearbox using measurements of the global responses. It is extremely costly to seed managed ... -
Fault Diagnosis of Floating Wind Turbine Drivetrain- Methodologies and Applications
Ghane, Mahdi (Doctoral theses at NTNU;2018:286, Doctoral thesis, 2018)Increasing demand for renewable energy is driving innovation and attracting many research resources all over the world. Wind energy is one of the most promising sources of renewable energy. Wind turbine has been in use for ... -
On the Joint Distribution of Excursion Duration and Amplitude of a Narrow-Band Gaussian Process
Ghane, Mahdi; Mogens, Blanke; Gao, Zhen; Moan, Torgeir (Journal article; Peer reviewed, 2018)The probability density of crest amplitude and duration that exceeds a given level is used in many theoretical and practical problems in engineering that are subjected to fluctuating loads such as wind and wave loads. The ... -
Statistical fault diagnosis of wind turbine drivetrain applied to a 5MW floating wind turbine
Ghane, Mahdi; Rasekhi Nejad, Amir; Blanke, Mogens; Gao, Zhen; Moan, Torgeir (Journal article; Peer reviewed, 2016)Deployment of larger scale wind turbine systems, particularly offshore wind turbine, requires more organized operation and maintenance strategies to make it as competitive as the classical electric power stations. It is ...
