title = "Impact of wind-speed ramps on turbines: from fluid-dynamic to aeroelastic simulation, via observed joint statistics",
abstract = "This report documents DTU contributions to Carbon Trust{\textquoteright}s Offshore Wind Accelerator (OWA) project, entitled “OWA Impact of Gusts on Loads and Power Production”; it was subcontracted through the Fraser-Nash Consultancy ({\textquoteleft}FNC{\textquoteright}). The focus of DTU{\textquoteright}s work—and the original design of the project—is detection of wind speed ramps and statistical characterization of their relevant metrics, and their effects on a wind farm. The latter is done through a model chain including large-eddy simulation coupled to constrained Mann-model turbulence simulation and the aeroelastic code Flex5; the simulated wind farm and models{\textquoteright} configurations were chosen to compare with the R{\o}dsand 2 (R2) windfarm. FNC analysed limited SCADA and mast data from R2, whereas DTU{\textquoteright}s work used data from H{\o}vs{\o}re; this is because the R2 mast data was from heights below hub and did not cover 1 year—thus making it unusable for ramp statistics affecting the current generation of wind turbines. In terms of the OWA project, this report covers work package 2 ({\textquoteleft}event detection{\textquoteright}) and WP3 ({\textquoteleft}modelling{\textquoteright}).",
