Title: METHOD FOR DETERMINING WIND SPEED AND PLANT FOR PERFORMING SAID METHOD
Abstract:
The invention relates to a method for determining wind speed in a plant (1) having at least two wind turbines (2) spaced apart from each other. In order to determine the wind speed with high accuracy, according to the invention, the occurrence of a change in the local wind speed is sensed for the at least two wind turbines (2), whereupon at least one time difference by which the occurrence of the local changes at the at least two wind turbines (2) is offset is determined, whereupon the wind speed is determined on the basis of the time difference and the distance (3) between the wind turbines (2). The invention further relates to a plant (1) having at least two wind turbines (2) spaced apart from each other.
