6 FAQs about [Methods of testing wind turbine blades for wind power generation]

What technologies are used to test wind turbine blades?

This paper surveys the testing, inspecting and monitoring technologies for wind turbine blades, including mechanical property testing, non-destructive testing/inspecting, full-scale testing, structural health monitoring and condition monitoring.

How to test wind turbine blades?

Many full-scale testing methods of wind turbine blades have major combined with fatigue testing, static testing and modal testing. According to these literatures, fewer full-scale testing of big size blades have preformed which the blades length can over dozens of meters.

What is non-destructive testing in wind turbine blades (WTB)?

A Survey Non-Destructive Testing in Wind Turbine Blades (WTB). Most important and updated condition monitoring techniques and methods applied to WTB. Analysis the future trends and challenges of structural health monitoring systems in WTB. Condition monitoring systems to reliability, safety, maintainability and availability of WTB.

What inspection methods are used to inspect wind turbine blade damage?

We also discuss the inspection strategy during production and inspection methods during operation. Five non-contact NDT techniques, including thermography, radiography, machine vision, laser shearography testing, and microwave testing, are appraised to inspect wind turbine blade damage.

Do wind turbine blades need a condition monitoring system?

Any fault in wind turbine blades generates important downtimes, costs and energy production loss. Nowadays, new condition monitoring systems are appearing for Non-Destructive Testing applied to wind turbines blades. This paper has summarised and analysed the most important advances done in this field in the last few years.

What load configurations are used to test wind turbine blades?

The experimental investigation consisted of the following load configurations: flapwise bending and torsion. In , a full-scale 34 m composite wind turbine blade was tested to failure under flapwise loading. In additional, the LM Wind Power’s have performed some full scale testing for wind turbine blades.
