14:30 - 16:00 Designing and operating for reliability
This session will show the latest studies carried out for analysing failure rates for wind turbine main components and sub-assemblies, both for offshore and onshore wind farms. Developments and a case study, in order to extend wind turbines life and solutions for avoiding catastrophic incidents, will be considered.
Delegates will be able to:
- Examine failure statistics for the major wind turbine sub-assemblies
- Identify failure mechanisms for selected components
- Recognise the cost implications of component failures
- Define studies and strategies for extend wind turbine life
- Analyse specific systems (converter, foundations) failures and behaviour for improving the performance
- Failure Models and Effect Analysis applied to wind turbine sub-assemblies

Katharina Fischer graduated in electrical engineering at Leibniz Universitaet Hannover in Hanover, Germany, in 2002 and received the Ph.D. degree from the Faculty of Mechanical Engineering of the same university in 2008. From 2009, she worked as a postdoctoral researcher at Chalmers University of Technology in Gothenburg, Sweden, until she joined the Fraunhofer Institute for Wind Energy and Energy System Technology (IWES) in Hanover, Germany, as a Senior Scientist in 2012. Her research interest includes the reliability, condition monitoring and maintenance of wind turbines, with a particular focus on the power converter.
