Abstract

Increasing cost pressure on the wind energy sector leads to the necessity of developing more reliable wind turbines in a cost and time optimized design process. Yet, current deficiencies in the load calculation methods for the gearbox and its components still impair the cost efficiency of the gearbox design process. The before mentioned deficiencies originate especially in the disregarding of system wide dependencies and interactions of the turbines drive train components. Thus, the main objective of this contribution was to develop modelling methods that can capture the effect of said correlations onto the loads. Therefore, a MBS based entire system simulation model was developed, validated extensively with measurements und finally evaluated using internationally accepted state of the art methods. The validation was carried out using measurement results of a generic research turbine that was operated under realistic conditions on a system test bench. The results of the validation were presented and the resulting conse-quences for the modelling methods were discussed and evaluated. The concluding evaluation of the method was carried out by comparing the results to those of a design load calculations according to the IEC 61400 as well as to a model implemented according to the recommendation of the Germanischer Llyod. The benefits of the method were elaborated and evaluated in the context of the overall objective.
