Modelling and Evaluation of Wind Speed Time Series for Reliability Analysis of Offshore Wind Farms (2014)
Presentation / Conference Contribution
Smith, C., Crabtree, C., Matthews, P., & Kazemtabrizi, B. (2014). Modelling and Evaluation of Wind Speed Time Series for Reliability Analysis of Offshore Wind Farms.

This paper outlines proposed testing criteria for wind speed time series (WSTS) models. The objective is to assess their suitability for reliability analysis that is dependent on an accurate representation of weather patterns. Two WSTS models were an...

Determining the Wind Speed Distribution within a Wind Farm considering Site Wind Characteristics and Wake Effects (2014)
Presentation / Conference Contribution
Ahmad, T., Smith, C., Matthews, P., Crabtree, C., & Kazemtabrizi, B. (2014). Determining the Wind Speed Distribution within a Wind Farm considering Site Wind Characteristics and Wake Effects.

This paper introduces a wind speed model for simulating the distribution of wind speeds within a wind farm. The model combines a macro scale wind speed time series (WSTS) model based on a continuous Markov process with a wake flow model, based on the...

Detection of Rotor Electrical Asymmetry in Wind Turbine Doubly-Fed Induction Generators (2014)
Journal Article
Zaggout, M., Tavner, P., Crabtree, C., & Ran, L. (2014). Detection of Rotor Electrical Asymmetry in Wind Turbine Doubly-Fed Induction Generators. IET Renewable Power Generation, 8(8), 878-886. https://doi.org/10.1049/iet-rpg.2013.0324

This study presents a new technique for detecting rotor electrical faults in wind turbine doubly-fed induction generators (DFIGs), controlled by a stator field-oriented vector control scheme. This is a novel method aimed at detecting and identifying... Read More about Detection of Rotor Electrical Asymmetry in Wind Turbine Doubly-Fed Induction Generators.

By analysing data from the Signal Conditioning and Data Acquisition (SCADA) systems fitted to wind turbines (WT) their manufacturers, Operators and other experts are able to monitor and improve WT performance. This survey summarises and describes the... Read More about Survey of Commercially Available SCADA Data Analysis Tools for Wind Turbine Health Monitoring.

Survey of commercially available condition monitoring systems for wind turbines (2014)
Report
Crabtree, C., Zappalá, D., & Tavner, P. (2014). Survey of commercially available condition monitoring systems for wind turbines. UK EPSRC SUPERGEN Wind Energy Technologies programme

As wind energy assumes greater importance in remote and offshore locations, effective and reliable condition monitoring techniques are required. Failure rate and downtime studies have also highlighted a need for condition monitoring of particular win...

Side-band algorithm for automatic wind turbine gearbox fault detection and diagnosis (2014)
Journal Article
Zappalá, D., Tavner, P., Crabtree, C., & Sheng, S. (2014). Side-band algorithm for automatic wind turbine gearbox fault detection and diagnosis. IET Renewable Power Generation, 8(4), 380-389. https://doi.org/10.1049/iet-rpg.2013.0177

Improving the availability of wind turbines is critical for minimising the cost of wind energy, especially offshore. The development of reliable and cost-effective gearbox condition monitoring systems (CMSs) is of concern to the wind industry, becaus...
