PIBE project organisation

A project structured in 3 work packages

Work Package 1 : Characterizing the amplitude modulation phenomena

Amplitude modulation phenomena, particularly those associated with dynamic stall on wind turbine blades, are a source of intense and intermittent noise that can cause noise annoyance. WP 1 aims to characterize and understand the relationship between the occurrence of dynamic stalls and the meteorological and operational conditions of the wind turbine on a given site.

3 approaches  are explored: characterization of dynamic stall noise in a controlled environment (anechoic wind tunnel measurements), measurement of stall noise in situ and correlation with atmospheric conditions, modelling of wind turbine noise amplitude modulations
