Abstract

A control system (111, 121) for positioning at least two floating wind turbines (110, 120) in a wind farm (100) is described. The control system (111, 121) comprises: a measurement device (112, 122) configured to measure an incoming wind field at the two wind turbines; a determination device (114, 124), where the determination device (114, 124) is configured to determine wake characteristics (151, 252, 351, 352) at the two wind turbines, where the determination device (114, 124) is configured to determine a propagation path of the wake characteristics (151, 252, 351, 352) through the wind farm (100) based on the determined wake characteristics (151, 252, 351, 352) at the at least two floating wind turbines (110, 120), wherein the determination device (114, 124) is configured to determine a position of each of the at least two floating wind turbines (110, 120) comprising a minimized wake effect based on the determined propagation path of the wake characteristic (151, 252, 351, 352) through the wind farm (100); and a repositioning device (113, 123) configured to reposition each of the at least two floating wind turbines (110, 120) to the determined position. Furthermore, a wind farm (100) is described, comprising at least two floating wind turbines (110, 120) and the above control system (111, 121). Furthermore, a method for positioning at least two floating wind turbines (110, 120) in a wind farm (100) is described.

Description

technical field [0001] The present invention relates to a control system for positioning at least two floating wind turbines in a wind farm. Furthermore, the invention relates to a wind farm and a method for positioning at least two floating wind turbines in a wind farm. Background technique [0002] In the technical field of floating wind turbines, it is known to install a plurality of floating wind turbines in a floating wind farm. Floating wind turbines installed in wind farms interact with each other through their wakes. A floating wind turbine wake is created because the floating wind turbine extracts energy from the incoming wind flow. The wake results in a decrease in wind speed, also known as wind starvation, and an increase in wind speed variation, also known as turbulence. These phenomena lead to a decrease in the total power production of the wind farm and an increase in the load of the downstream floating wind turbines. Downstream floating wind turbines refer...
