Wind Power

1. Introduction to Wind Measurement and Data Analysis

2. Why do we need wind data? P wind = ½  V 3 Average wind speed – to calculate the energy output of a wind turbine Average wind direction – to optimize wind farm layout Maximum wind speed – to assess mechanical loading on turbines Standard deviation – to calculate the turbulence intensity of the wind Air temperature / atmospheric pressure – to calculate air density
