The onshore wind turbine industry must overcome many technical, commercial, and environmental difficulties. A significant element for planning consent is operational noise. Acoustic limits are strictly enforced and can lead to near-neighbour complaints as well as contractual disputes. Reactec have diagnosed, analyzed and solved a problematic tonal resonance using ANSYS 12.1. This paper presents the measurement, analysis, modelling and solution simulation process when tackling a tonal noise issue in a megawatt scale wind turbine. Extensive modelling and simulation of the entire turbine system allows an in-depth diagnosis as well as a virtual test bed for solution design. The analysis reveals a complex interaction between gearbox resonances, ...
