Turbine power production sensitivity to coastal sheared and turbulent inflows
Inflows with identical wind speeds at turbine hub height can generate varying amounts of power, depending on parameters such as vertical shear and turbulence intensity. At a commercial wind farm located in Southwestern Ontario off the shores of Lake Erie, the wind profile approaching a multi-megawatt horizontal-axis turbine has been characterized by a meteorological mast and then correlated with resulting power production across a range of hub height speeds. Using data collected over a six-month measurement campaign, inferences have been drawn on the sensitivity of turbine performance to sheared and turbulent inflows for both land and lake-influenced winds at the coastal site under study.
