Embodiment Construction
[0020] 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.
[0021] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0022] A control method for normal operation of wind turbine anemometer after damage, such as figure 2 shown, including the following steps:
[0023] Step 1, for example, after detecting that the anemometer of the 3# fan is damaged and cannot measure the wind speed, obtain the position parameters, wind direction parameters and wind speed parameters of the adjacent 1#, 2#, and 4# fans through the communication between the wind farm fans;
[0024] as attached figure 1 , set the position of 1# blower fan as east longitude x1° north latitude y1° and the wind direction measured is z1° (during the wind direction measurement in this embodiment, true north is 0°) and the wind speed is v1; 2# ...

The invention provides a control method for normal operation of a wind generation set after damage of an anemograph. The control method comprises the following steps that (1) after the anemograph of a certain fan is damaged, the position parameters, the wind direction parameters and the wind speed parameters of other fans adjacent to the fan are obtained; (2) the included angles between all the adjacent fans and the due north direction are calculated, and the direction is consistent with the measured wind direction in standard; (3) a wind direction mean value is calculated according to the wind direction values of all the adjacent fans, and which included angle range between the damaged fan and any other two adjacent fans the wind direction mean value is within is judged; (4) the maximum value of the wind speed values of the two adjacent fans, obtained in the step (3), at the included angle is obtained; and (5) the maximum value of the wind speed values is used as the wind speed reference value of the damaged fan. The control method has the following advantages that when the anemograph of the wind generation set is damaged and the wind speed cannot be obtained, the wind generation set can normally operate according to wind speed data measured by the adjacent fans, so that the utilization rate is increased, and more electric energy is obtained.
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 wind turbine anemometer to operate normally after being damaged. Background technique [0002] During normal operation, the wind turbine needs to judge whether the current wind speed meets the power generation conditions based on the wind speed measured by the anemometer. The wind speed is too low to drive the generator to a sufficient speed for power generation, and the wind speed is too high. The wind turbine load cannot withstand the load and cannot generate electricity. [0003] In the existing technology, 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 speed, and cannot know whether the current wind speed meets the power generation conditions, so it can only stop and waste the wind energy.
