Design of generator wind bag test scheme

Can a bench-top test rig simulate a wind turbine?

This paper discusses the development of a bench-top test rig which is designed to mimic the operating condition of an actual wind turbine and use it for monitoring its condition so as to diagnose the incipient faults in its critical components using latest machine learning algorithms such as Artificial Neural Network (ANN).

Can a wind turbine drivetrain be tested in a nacelle test rig?

This is why the aim of this thesis work is to develop a structured methodology which can be implemented to test a wind turbine drivetrain, or more specifically the gearbox, in a nacelle test rig in order to proof the correct operation of it and determine its critical operating conditions, before it is put in a field to produce power.

How can a nacelle test rig simulate wind and grid conditions?

This can be done in a nacelle test rig equipped with a multi-physics hardware in the loop system in which wind and grid conditions can be simulated, like the 4 MW capacity test rig installed in the CWD (Center for Wind Power Drives) in Aachen, Germany.

Is there a standard methodology to test a wind turbine?

In the wind industry, it does not exist a standard methodology to test a wind turbine or any of its components. The IEC 61400 standard is a guideline for the certification of installed wind turbines or their single components. It does not include measurement of entire nacelles or drivetrains on system test benches.

How is a wind turbine gearbox tested?

A wind turbine gearbox is normally tested in a back-to-back arrangement. Nevertheless, in the testing methodology that will be described along this document the gearbox will be only tested inside the nacelle, in a nacelle test rig.

How does a wind turbine test bench work?

The test bench provides the option wind turbine nacelles under real conditions to operate. By simulating wind conditions in combination with a dynamic load unit loads may be imposed by the rotor. The electrical grid is also represented by a real-time simulation, allowing the resulting loads on the drivetrain impart.
