Periodic Report 2 - PROTEST (PROcedures for testing and measuring wind energy systems)

Project ID: 212825
Funded under: FP7-ENERGY

Abstract

The PROTEST project was a European funded project within the Seventh Framework Programme (FP7) which led in some first suggestions to improve the standards concerning the wind turbine prototype testing focusing on the mechanical components.

A major weak point in the former approach that had been adopted was that the aero-elastic tools did not include the necessary information about the mechanical components. For this reason three cases have been identified which needed further simulations to improve the current standards. These are the cases of low voltage ride through and an electrical fault in the grid may have a large impact on the loads of turbine. Though electrical faults were included in those standards, the simulating tools were not able to simulate these cases sufficiently. The possibility of resonance concerning the gearbox should be investigated in different frequency ranges. And finally, considering the possible misalignment in the drive train, simulations should be performed including the maximum allowed misalignment.

A description concerning the loads that should be provided to the component manufacturer was given to answer the question of how loads could be communicated between the component manufacturer and the wind turbine manufacturer.

The results of the project include a flexible approach that can be adopted to set up and use a prototype measurement campaign to validate the model and possibly improve the model characteristics. As the mechanical components' buildup varies widely in wind turbines while at the same time the models available vary, as well, it was concluded that only a flexible method would be useful.
