Forward Simulation of Air and Ground Vibration Induced by Series of Wind Turbines Using the Spectral-Element Method

Description: 

Amidst the ongoing energy transition, wind power, harnessed via turbines, has been identified as a viable renewable energy source capable of generating clean, sustainable power. As wind turbines harness the wind's energy to produce electricity, they introduce sub-aerial and subsurface vibrations that can be observed in seismic and acoustic recordings. Elastic and acoustic wave propagation from turbine sources was simulated using the spectral-element method implemented in SPECFEM3D across a spectrum of frequencies ranging from 1 to 10 Hz across a diverse set of subsurface conditions. Numerical results were compared with observations from turbine installations in Wolfe Island, Ontario for validation. Comprehensive synthetic modelling of these coupled wavefields allows us to characterize the noise introduced by these power-generating structures and to assess their impact on nearby people and infrastructure. Further, the wavefield characterization allows for the investigation of turbines as a seismic source that can lead to monitoring solutions for structural foundation and installation integrity.
