Abstract
A method of constructing roughness change model for wind farm micro-sitting includes following steps. A roughness change model is established. The roughness change model is resolved. The step of establishing the roughness change model includes that a wind flow from upstream reaches an anemometer tower after being disturbed by two roughness change, and a wind profile of the wind turbine comprises a first portion, a second portion, and a third portion. The first portion is described with a first roughness and a first friction velocity, the second portion is described with a second roughness and a second friction velocity, and the third portion is described with a third roughness and a third friction velocity.
