Abstract
Official abstract text for this publication.
A method of controlling a plurality of wind turbines of a wind park includes: determining an axial induction zone of at least a wind turbine of the wind park; and modifying the axial induction zone for controlling wind farm blockage by adjusting at least one of the following operational variables: a yaw angle of a blade rotor of the wind turbine, a pitch offset angle of at least one blade of the blade rotor, a rotor speed of the blade rotor.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of controlling a plurality of wind turbines of a wind park, the method comprising: determining an axial induction zone of at least a wind turbine of the wind park, wherein the axial induction zone is determined based on at least one of the following input parameters: inflow wind direction, inflow wind speed, and inflow wind turbulence; and modifying the axial induction zone for controlling wind farm blockage by adjusting at least one of the following operational variables: a yaw angle of a blade rotor of the wind turbine, a pitch offset angle of at least one blade of the blade rotor, a rotor speed of the blade rotor. 2. The method according to claim 1 , wherein at least one table or function is generated for correlating the input parameters to the operational variables. 3. The method according to claim 2 , wherein the at least one table or function optimizes the power production of the wind park by determining a set of operational variables for each set of input parameters. 4. The method according to claim 1 , wherein the operational variable is derived, such that the power production of the wind park is optimized. 5. The method according to claim 1 , wherein the operational variable is derived, such that the structural loads are optimized on at least one wind turbine of the wind park. 6. A control device controlling a plurality of wind turbines of a wind park, the control device comprising a processor adapted to determine an axial induction zone of at least a wind turbine of the wind park, the axial induction zone being determined based on inflow wind direction or an inflow wind speed or an inflow wind turbulence, and generate a control setting of at least one wind turbine of a wind park for modifying the axial induction zone by adjusting at least one of the following operational variables for controlling wind farm blockage: a yaw angle of a blade rotor of the wind turbine, a pitch offset angle of at least one blade of the blade rotor, a rotor speed of the blade rotor. 7. A wind park, comprising: a plurality of wind turbines; and the control device according to claim 6 connected to the wind turbines to supply the respective control setting to each wind turbine.
