In an embodiment of the application, the performing a untwisting or reversing untwisting operation includes;
s201: the rotation angle of the engine room is positioned between the first angle threshold value and the second angle threshold value, when the wind speed data is smaller than the wind speed threshold value, the cable releasing operation is carried out, and when the wind speed data is larger than the wind speed threshold value, the normal power generation is carried out;
specifically, the rotation angle of the nacelle is located between the first angle threshold and the second angle threshold, and when the wind speed data is greater than the wind speed threshold, normal power generation is performed. When the wind speed threshold is larger than the wind speed threshold, the wind speed is larger, more electric energy can be obtained when the wind speed is generated, the power generation efficiency is improved, and the power generation can be performed.
Meanwhile, when the wind speed data is smaller than the wind speed threshold value, if power generation is continued at this moment, the obtained electric energy is smaller, the power generation efficiency is lower, the shutdown operation is carried out on the wind turbine generator, and the cable disassembly operation is carried out on the corresponding driving device.

In this embodiment, the first angle threshold may be set to 400 °, the second speed threshold may be set to 680 °, the third speed threshold may be set to 500 °, and the wind speed threshold may be 3m/s.
Specifically, when the wind direction changes, the angle of rotation of the cabin in the same direction reaches 400 degrees and does not reach 680 degrees, the control system detects wind speed information, when the average wind speed of 10min is detected to be less than 3m/s, the control system gives an instruction, the unit is stopped rapidly, and the driving device executes a corresponding cable releasing process program; when the angle of the cabin rotating in the same direction reaches 680 degrees, after a signal is transmitted to the control system by the limit switch, the automatic control system enables the unit to stop rapidly and reversely unwind the cable, when the angle of the cabin is less than 500 degrees and the cabin is opposite to wind, the cable release is stopped, the unit starts to generate electricity, and when the average wind speed is less than 3m/s after the control system detects 10min, the cable release is continued.
In one embodiment of the application, because the wind field is generally relatively large, a large number of fans are installed in the station, each fan is provided with a wind speed and wind direction sensor, and the wind speed and wind direction which are received by the peripheral fans can be predicted by combining the wind speed and wind direction of one fan with the wind speed and wind direction control of the other fan.
Specifically, the coordinates of the positions of all fans are recorded. The wind speed and the wind direction of each fan are monitored in real time. Generally, the wind directions of all fans are substantially identical at the same time. Thus, the wind direction of a wind next to a certain fan can be predicted from the current wind direction.
Acquiring wind direction data and wind speed data of a plurality of fans; the fans which firstly acquire wind direction data and wind speed data transmit the data to other fans; each fan judges whether to rotate the wind or not according to the wind direction data and the wind speed data.
Specifically, judging whether wind rotation is performed includes; pre-estimating the wind speed reaching the fan; if the wind speed is greater than the wind speed threshold value, rotating the cabin to generate electricity for wind; when the wind speed reaching the fan is smaller than the wind speed threshold value, no executing action is performed.
Furthermore, the wind speed of a certain fan can be judged to be the next wind-receiving wind speed according to the wind speed decreasing rule of a plurality of fans at the front end of the wind direction, and the decreasing degree of the wind speed passing through each fan can be obtained through long-term operation records. The wind speed and direction change rule of wind after passing can be obtained for the areas with flatter terrain and the uneven areas after long-term operation, so that the wind speed and direction change rule can be used for guiding the wind untwisting cable in the later period. The data record of the early operation can be used for more rapidly deducing, so that the operation load is reduced.
Specifically, in an embodiment of the present application, the pre-estimating the wind speed reaching the fan includes setting a plurality of partitions for the wind direction obtaining range, and recording the wind speed values of the fans reached by the wind directions of a plurality of groups of the same partition, so as to obtain the change rates of a plurality of groups of wind speed values decreasing in sequence; obtaining the wind speed change rate of the partition finally through a mathematical calculation method according to a plurality of groups of change rates; and pre-estimating the wind speed value of a certain fan through the wind speed change rate.
For example, the whole wind direction is 360 degrees, the wind direction is divided into 12 areas, the wind speed of one area is estimated, when the wind in the direction blows, each fan generates wind speed data, the wind speed data are arranged according to the magnitude of wind speed values, on a coordinate system, the wind speed magnitude is taken as a horizontal axis, the distance between the fans which firstly obtain the wind power from the distance between the fans which are arranged behind is taken as a vertical axis, the distribution of wind speed values is simulated, the change rate of wind speed reduction is found, by adopting the mode, multiple groups of data can be adopted, and finally the average value of the multiple groups of values is taken, so that the wind speed change rate is obtained.
Therefore, after the first fan obtains wind power in a certain wind direction area, the wind speed threshold value reaching a certain fan can be estimated according to the wind speed change rate, and whether wind rotation is carried out or not is judged.
Similarly, all wind speed change rates of 12 regions can be obtained.
Accordingly, the wind receiving direction of the fan can be adjusted in advance to receive the optimal wind speed, wind and cable untwisting can be carried out in a poor wind speed time period, and efficient power generation can be carried out in a good wind speed time period. So as to achieve the highest power generation efficiency.

and the second judging module is configured to set a third angle threshold when the nacelle performs reverse cable-releasing, and stop cable-releasing and start power generation when the nacelle reaches the third angle threshold.
In an embodiment of the present application, the first determining module further includes;
