Automated Wind Turbine Pitch Fault Prognosis using ANFIS (2013)
Presentation / Conference Contribution
Chen, B., Matthews, P., & Tavner, P. (2013, February). Automated Wind Turbine Pitch Fault Prognosis using ANFIS. Presented at EWEA 2013, Vienna, Austria

Many current wind turbine (WT) studies focus on improving their reliability and reducing the cost of energy, particularly when WTs are operated offshore. WT Supervisory Control and Data Acquisition (SCADA) systems contain alarms and signals that prov... Read More about Automated Wind Turbine Pitch Fault Prognosis using ANFIS.

Invariants of the reduced velocity gradient tensor in turbulent flows (2013)
Journal Article

In this paper we examine the invariants p and q of the reduced 2×2 velocity gradient tensor (VGT) formed from a two-dimensional (2D) slice of an incompressible three-dimensional (3D) flow. Using data from both 2D particle image velocimetry (PIV) m... Read More about Invariants of the reduced velocity gradient tensor in turbulent flows.

Insight Report: Domestic Time of Use Tariff: A comparison of the time of use tariff trial to the baseline domestic profiles (2013)
Report
Whitaker, G., Wardle, R., Barteczko-Hibbert, C., Matthews, P., Bulkeley, H., & Powells, G. (2013). Insight Report: Domestic Time of Use Tariff: A comparison of the time of use tariff trial to the baseline domestic profiles. Northern Powergrid (Northeast) Limited, Northern Powergrid (Yorkshire) Plc, British Gas Trading Limited EA Technology Ltd and the University of Durham

Peak electricity demand poses a particular challenge both to network operators and to energy suppliers. A reduction in peak demand would allow existing networks to accommodate load growth with lower investment, and also reduce the cost of electricity...
