Electrical & Mechanical Diagnostic Indicators of Wind Turbine Induction Generator Rotor Faults (2018)
Journal Article
Zappalá, D., Sarma, N., Djurović, S., Crabtree, C., Mohammad, A., & Tavner, P. (2019). Electrical & Mechanical Diagnostic Indicators of Wind Turbine Induction Generator Rotor Faults. Renewable Energy, 131, 14-24. https://doi.org/10.1016/j.renene.2018.06.098

In MW-sized wind turbines, the most widely-used generator is the wound rotor induction machine, with a partially-rated voltage source converter connected to the rotor. This generator is a significant cause of wind turbine fault modes. In this paper,... Read More about Electrical & Mechanical Diagnostic Indicators of Wind Turbine Induction Generator Rotor Faults.

Non-intrusive torque measurement for rotating shafts using optical sensing of zebra-tapes (2018)
Journal Article
Zappalá, D., Bezziccheri, M., Crabtree, C., & Paone, N. (2018). Non-intrusive torque measurement for rotating shafts using optical sensing of zebra-tapes. Measurement Science and Technology, 29(6), Article 065207. https://doi.org/10.1088/1361-6501/aab74a

Non-intrusive, reliable and precise torque measurement is critical to dynamic performance monitoring, control and condition monitoring of rotating mechanical systems. This paper presents a novel, contactless torque measurement system consisting of tw... Read More about Non-intrusive torque measurement for rotating shafts using optical sensing of zebra-tapes.

An Effective Approach for Rotor Electrical Asymmetry Detection in Wind Turbine DFIGs (2018)
Journal Article
Ibrahim, R. K., Watson, S. J., Djurović, S., & Crabtree, C. J. (2018). An Effective Approach for Rotor Electrical Asymmetry Detection in Wind Turbine DFIGs. IEEE Transactions on Industrial Electronics, 65(11), 8872-8881. https://doi.org/10.1109/tie.2018.2811373

Determining the magnitude of particular fault signature components (FSCs) generated by wind turbine (WT) faults from current signals has been used as an effective way to detect early abnormalities. However, the WT current signals are time-varying due... Read More about An Effective Approach for Rotor Electrical Asymmetry Detection in Wind Turbine DFIGs.
