Embodiment Construction
[0019] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.
[0020] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0021] A control method for normal operation of the anemometer of a wind turbine after damage, such as figure 2 shown, including the following steps:
[0022] Step 1, for example, after detecting that the anemometer of the 3# wind turbine is damaged and the wind direction cannot be measured, the position parameters and wind direction parameters of the adjacent 1#, 2#, and 4# wind turbines are obtained through the communication between the wind farm fans;
[0023] as attached figure 1 , if the position of 1# blower fan is east longitude x1 ° north latitude y1 ° the measured wind direction is z1 ° (when the wind direction measurement in this embodiment is 0 ° with true north); the wind ...

The invention provides a control method for ensuring normal running after damage of a wind indicator of a wind turbine unit. The control method comprises the following steps: 1) after the wind indicator of the certain wind turbine unit is damaged and incapable of measuring a wind direction, acquiring position parameters and wind direction parameters of other adjacent wind turbine units of the certain wind turbine unit; 2) calculating included angles between the adjacent wind turbine units and a due north direction, and keeping the included angles consistent with those in a direction standard during wind direction measurement; 3) evaluating the wind direction average value of the wind direction parameters of all the adjacent wind turbine units, and judging which two adjacent wind turbine units form the included angles within which the wind direction average value is located, with the damaged wind turbine unit; and 4) evaluating the wind direction average value of the two adjacent wind turbine units forming the included angles, and using the average value as a wind direction reference value of the damaged wind turbine unit. The control method provided by the invention has the following advantage: the wind turbine unit is capable of carrying out wind alignment according to the wind direction data measured by the nearby wind turbine units and normally running when the wind indicator of the wind turbine unit is damaged and incapable of acquiring the wind direction.
Description
technical field [0001] The invention belongs to the technical field of wind turbine control, and in particular relates to a control method for the normal operation of the anemometer of the wind turbine after damage. Background technique [0002] During normal operation, the wind turbine needs to face the wind in real time according to the wind direction measured by the anemometer to ensure that the wind turbine is facing the wind direction and generating electricity normally. [0003] In the prior art, the wind turbine can only use the local anemometer to measure data. When the anemometer is damaged, the wind turbine cannot know the current wind direction, cannot complete the wind control of the wind turbine, and can only stop the wind turbine, which wastes wind energy. Contents of the invention [0004] In view of this, the present invention aims to propose a control method for the normal operation of the anemometer of the wind turbine unit after damage, so as to solve th...
