Condition Monitoring of Rotating Electrical Machines (2020)
Book
Tavner, P. J., Ran, L., & Crabtree, C. J. (2020). Condition Monitoring of Rotating Electrical Machines. (3rd ed.). Institution of Engineering and Technology (IET)

Condition monitoring of engineering plants has increased in importance as engineering processes have become increasingly automated. However, electrical machinery usually receives attention only at infrequent intervals when the plant or the electricit... Read More about Condition Monitoring of Rotating Electrical Machines.

Validation of a non-contact technique for torque measurements in wind turbines using an enhanced transient FSV approach (2019)
Journal Article

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.

Impact of wind conditions on thermal loading of PMSG wind turbine power converters (2017)
Journal Article
Smith, C., Crabtree, C., & Matthews, P. (2017). Impact of wind conditions on thermal loading of PMSG wind turbine power converters. IET Power Electronics, 10(11), 1268-1278. https://doi.org/10.1049/iet-pel.2016.0802

Power converter reliability is critical for permanent magnet synchronous generator (PMSG) wind turbines. Converter failures are linked to power module thermal loading but studies often neglect turbine dynamics, control and the impact of wind speed sa...
