What is the optimal turbine spacing for a wind farm?

Depending on the ratio of land surface costs and turbine costs, different optimal spacings have been obtained. For realistic cost ratios, we found that the optimal average turbine spacing may be considerably higher ( 15D) than conventionally used in current wind farm implementations ( 7D).

Are single lines of wind turbines better than clusters of turbines?

In order to minimise the wake losses, single lines of wind turbines with considerable distance between the individual rows are more preferable than clusters of turbines, leading to the layout-example shown in Figure 3.

How are distances between dwellings and wind power installations ensured?

Distances between dwellings and wind power installations are ensured mainly in two ways. First, immission control regulations enforce levels of noise and visual impacts to be below well-defined thresholds. Whether a turbine can be built in a certain location thus depends on the characteristics of the planned turbine and is decided on

What is the recovery distance behind a wind farm?

Assuming a wind speed of 10 m/s at hub-height the recovery distance behind the wind farm (to within 2% of the freestream) was found to vary between 7.5 and 8.5 km from the last turbine in the wind farm according to the value assigned to the roughness (0.1 m to 1 m).

How a 72 MW wind farm is connected to the HV distribution network?

Sample structure of internal electrical network of the 72 MW wind farm connected to the HV distribution network There are different ways of connecting wind farms to the HV network depending, among other things, on the power level of a wind farm, distance to the HV substation and the number of wind farms connected to the sequencing lines.
