Between 10 degree~15 degree, the radius of P1 instruction indicates the tired of wind power generating set power data corresponding with the affiliated wind direction section A
It is value added.
Table 1 is the tables of data of corresponding with Fig. 6 power and wind rose map.
First is classified as wind direction section number in table 1, and second is classified as the corresponding angular range in each wind direction section, and third is classified as respectively
The corresponding power data accumulated value in wind direction section, can facilitate the logical operation of program using data sheet form.
Table 1
As shown in table 1, the power data accumulated value in wind direction section 3,10 °~15 ° of north by west is M0, and X4<M0<
X5, and the air speed data accumulated value in remaining wind direction section is 0.I.e. not on the direction of wind, the air speed data of wind power plant is tired
Value added is 0.
In step 4022, according to operating condition and wind rose map, predict whether the wind direction of wind power plant changes.
Specifically, step 4022 may include following three sub-steps：
(1) judge whether operating condition wind direction corresponding with the radius of wind rose map section changes.
(2) if operating condition wind direction corresponding with the radius of wind rose map section changes, judge former wind direction section pair
Whether the radius answered reduces, and whether the new corresponding radius in wind direction section increases.
(3) if the corresponding radius in former wind direction section reduces, and the new corresponding radius in wind direction section increases, then predicts wind-powered electricity generation
The wind direction of field changes.
Below with reference to Fig. 6 and Fig. 7, carried out to based on power and the wind vector of the wind power plant of wind rose map prediction process
It is described in detail.
Fig. 7 be another embodiment of the present invention provides power and wind rose map schematic diagram.
Power wind direction corresponding with the radius of wind rose map section in Fig. 7 changes, while including two wind directions
Section：10 °~15 ° of 10 °~15 ° of north by west and north by east.In conjunction with Fig. 3 it is found that 10 °~15 ° of north by west is wind belonging to wind direction A
To section, 10 °~15 ° of north by east is wind direction section belonging to wind direction B.Since the wind direction of wind power plant is B from A variation, here will
Wind direction section belonging to wind direction A is as former wind direction section, using wind direction section belonging to wind direction B as new wind direction section.
Table 2 is the tables of data of corresponding with Fig. 7 power and wind rose map.
Table 1
| Wind direction section number | Angular range | Power data accumulated value |
| 1 | 0 °~5 ° of north by west | 0 |
| 2 | 5 °~10 ° of north by west | 0 |
| 3 | 10 °~15 ° of north by west | M1 |
| 4 | 15 °~20 ° of north by west | 0 |
| …… | …… | …… |
| 19 | 0 °~5 ° of north by east | 0 |
| 20 | 5 °~10 ° of north by east | 0 |
| 21 | 10 °~15 ° of north by east | 0 |
| 22 | 15 °~20 ° of north by east | M2 |
| …… | …… | …… |
As shown in table 2, the power data accumulated value in wind direction section 3,10 °~15 ° of north by west becomes M1, M1=X4；
Wind direction section 22, i.e. power data accumulated value in 10 °~15 ° of north by east become M2, M2=X1；Wind in remaining wind direction section
Fast data accumulation value is 0, i.e., not on the direction of wind, the air speed data accumulated value of wind power plant is 0.
It is found that the length of the corresponding radius P1 instruction in the Central Plains Fig. 7 wind direction section is decreased at X4 compared with Fig. 6, new wind
The length indicated to the corresponding radius P2 in section increases at X4, illustrates that the wind direction of wind power plant just changes.
When actual prediction, the power and wind rose map of wind power plant can be scanned by central monitoring equipment 103, if scanning hair
Existing power changes with wind rose map, then continues to test whether the corresponding radius in former wind direction section becomes smaller, with stylish wind
Whether become larger to the corresponding radius in section, if the corresponding radius in former wind direction section becomes smaller, corresponding half with stylish wind direction section
Diameter becomes larger, then can determine that wind direction changes.
It should be noted that the technical solution in the embodiment of the present invention is based primarily upon former wind direction section and new wind direction section
Variation tendency the wind vector situation of wind power plant is predicted.Those skilled in the art can be according to actual needs to former wind
The increment value of decreasing value and new wind direction section to section is selected, herein without limiting.

It is in the step 403 in Fig. 4 can be refined as step 4031 and step 4032 in Fig. 8.
In step 4031, judge whether the new corresponding wind power generating set in wind direction section has executed yaw operation.
In step 4032, if the new corresponding wind power generating set in wind direction section has executed yaw operation, by wind-powered electricity generation
In other wind generating set yaws to new wind direction section in addition to having executed yaw operation.
When practical yaw, after the detection power of central monitoring equipment 103 changes with wind rose map, new wind direction is detected
The yaw mark of the corresponding wind power generating set in section.When the new corresponding wind power generating set in wind direction section yaws it automatically
Afterwards, wind power generating set issues preparation yaw mark then into wind power plant, and issues the wind direction value of new change, to exclude because manually
It yaws, untie the mooring rope, yawing maloperation caused by situations such as wind vane is abnormal.
Next, starting to detect after wind power generating set receives the preparation yaw mark that central monitoring equipment 103 issues
The wind direction of itself, if the wind direction value for the new change that the true wind direction of itself wind vane detection and central monitoring issue has deviation,
Then current blower is ready to carry out autonomous yaw.
As noted previously, as the embodiment of the present invention does not need to judge the coordinate of every wind power generating set, not yet
To blower before needing to preselect, but wind vector direction is automatically selected and detects by power and wind rose map, such as
By the accumulated value of performance number in power and wind rose map, determine whether that wind vector really occurs.In this way, if prediction
As a result it changes for the wind direction of wind power plant, it will be able to yaw operation be executed to wind power generating set in advance, there is control method
Simply, highly-safe, generated energy loss is small, is very suitable for promoting the use of.
