Wind Energy Acoustical Applications

Introduction
With the enormous growth of the wind turbine industry, noise related problems are becoming ever more pertinent to design, R&D, production and operation personnel. The webinar describes how Brüel & Kjær solutions can address these new challenges to optimise operation, increase product quality and simplify measurement procedures.

Programme topics

• Noise management of wind turbines and wind farms: permanent and semi-permanent solutions, how to handle noise complaints and ensure compliance with regulations.
• Sound and vibration systems for quality control for gearbox and generator test rigs: data acquisition and analysis systems for production, on-site trouble shooting and R&D facilities.
• IEC 61400-11 Wind turbine generator systems: acoustic noise measurement techniques: a complete system to determine sound power, tonality, impulsivity according to the international standard.
• Improve and optimise design through acoustical array technology: rugged, battery operated arrays with rapid set-up time, ideal for outdoor use. Large ground based arrays for precision noise source identification.
• Trends and perspectives: new technologies give new possibilities for transducers, systems and analysis techniques.
