Wake Effect Wind Farm
A precise tool.
What is the Wake Effect Wind Farm & How does it work?
The wake effect in wind farms refers to the reduction in wind speed behind wind turbines due to their interaction with the air flow. This phenomenon can significantly impact the overall efficiency and power output of a wind farm.
The Jensen model is a widely used method to estimate the wake deficit caused by upstream turbines. It assumes that the wake expands linearly downstream and that the wind speed deficit decays with distance according to a specific formula.
