Embodiment Construction

[0049] exist figure 1 The wind farm 1 shown in a schematic plan view in , comprises a plurality of wind turbines, which are arranged substantially in a square area and are marked with reference numerals A01 to A07 in the first row, and in the second row are marked with reference signs B01 to B07, ... are marked with reference signs F01 to F07 in the last sixth row. The wind park also comprises means 3 for controlling at least one considered wind turbine, eg wind turbine 5 (A07). Thus, the device 3 is adapted to determine based on the wind direction 7 (7a, . One of B05 ), 9d (B04 ) or 9e (A06 )) is in the wake region 11b caused by the wind turbine 5 under consideration. In the presently illustrated example, other wind turbines 9b (B06) are located in the wake region 11b downstream of the considered wind turbine 5 (A07) during the current wind conditions in which the wind blows in direction 7b . For example, if the wind is blowing in direction 7a (and close to wind turbine 5...

Abstract

It is described a method for controlling at least one considered wind turbine (5) in a wind park (1), comprising: determining, based on a wind condition (7b), in particular wind direction (7b), whether another wind turbine (9a-9e) is in a wake region caused by the considered wind turbine; if another wind turbine (9b) is the closest wind turbine in the wake region (lib) and if the other wind turbine (9b) is in an operable state, applying a first control setting (15) to the considered wind turbine (5); if the other wind turbine (Ob) is in a non-operable state applying a second control setting (17) to the considered wind turbine (5), wherein the first control setting is based on wind park level optimisation and the second control setting is based on wind turbine level optimisation.

Description

technical field [0001] The invention relates to a method and a device for controlling at least one considered wind turbine in a wind park comprising a plurality of wind turbines, and also to a wind park comprising the control device. Background technique [0002] A wind farm includes a number of wind turbines. Depending on the wind direction, some wind turbines are located downstream of other wind turbines. The upstream wind turbines reduce the wind speed and wind energy experienced by the downstream wind turbines. The wind shadow downstream or after the upstream wind turbine may also be referred to as a wake area. [0003] To reduce production losses caused by wind turbine wakes in a wind farm, optimized blade pitch, rotor speed, power production set point, rotor pitch and / or yaw offset or other control settings may be used on the wind turbine. When the wake of a wind turbine affects one or more other wind turbines in addition, the upstream wind turbine may adjust its co...
