Description

Technical Field

[0001] The invention relates to a wind power prediction device and a prediction method based on plateau mountain areas, belonging to the technical field of wind power prediction. Background Art

[0002] Wind power prediction technology refers to the prediction of the power that a wind farm can output in the future. In the process of predicting wind power in plateau areas, generally only the wind speed power generation in the area within a certain period of time is statistically predicted, and weather changes are not taken into account. However, weather changes will also have an impact on wind power prediction. Therefore, in the process of data collection and prediction, the weather factors at the collection location need to be taken into account.

[0003] A Chinese patent document with publication number CN118367605A discloses a small off-grid wind power generation system and a wind power prediction method. Data statistics are performed based on the small off-grid wind power generation system, and feature selection is performed through grayscale correlation analysis to obtain influencing factors with a high correlation with wind power, which can effectively improve the prediction accuracy. In the search process of the sparrow algorithm, an inertia weight factor and a Lévy flight strategy are added to expand the search range of the algorithm, improve the search ability of the algorithm, and establish an error prediction model, which can greatly improve the prediction accuracy of the model.

[0004] Although the small off-grid wind power generation system and wind power prediction method take into account influencing factors such as wind speed, air density, air pressure, temperature and wind direction, they do not provide further solutions on how to collect weather conditions. Summary of the invention

DETAILED DESCRIPTION

[0031] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0032] like Figures 1 to 4As shown, a wind power prediction device based on plateau and mountainous areas described in the present invention includes a wind turbine generator and a data acquisition mechanism, wherein the data acquisition mechanism is arranged on the wind turbine generator, and the data acquisition mechanism includes an acquisition frame 2 and a controller 10, a weather acquisition component, an electric power acquisition component 4 and a wireless transceiver module 5 installed in the acquisition frame 2, wherein the controller 10 is electrically connected to the weather acquisition component, the electric power acquisition component 4 and the wireless transceiver module 5. When in use, the weather conditions are collected through the weather acquisition component, and the electric power of the wind turbine generator is collected through the electric power acquisition component 4. After the controller 10 receives the relevant data of the weather and the electric power, it performs remote data transmission through the wireless transceiver module 5, so as to facilitate the prediction of the wind power of the wind turbine generator.

[0033] The wind turbine generator comprises a generator body 1 and fan blades 3 , wherein the fan blades 3 are sleeved on the input shaft of the generator body 1 .

[0034] The acquisition frame 2 is arranged on the outer shell of the generator body 1 .

[0035] The weather collection component includes a convex mirror 7, a heated aluminum plate 9 and an infrared temperature controller 8. The convex mirror 7 is arranged at the upper end of the collection frame 2. The heated aluminum plate 9 is located directly below the convex mirror 7 and is connected to the inner wall of the collection frame 2 through a plurality of fixing rods 6. The infrared temperature controller 8 is electrically connected to the heated aluminum plate 9 and the controller 10.

[0036] The gap between the convex mirror 7 and the collection frame 2 is filled with sealant. The gap between the convex mirror 7 and the collection frame 2 is sealed by the sealant to ensure the sealing of the connection between the convex mirror 7 and the collection frame 2.

[0037] The upper end of the collection frame 2 is provided with a plurality of convex mirror pressing assemblies that rotate in a circular array.

[0038] The convex mirror pressing assembly includes a rotating block 12, an operating block 14 and a rubber stopper 13. A rotating groove 11 is provided at the upper end of the acquisition frame 2, and the longitudinal section of the rotating groove 11 is in a convex shape. The rotating block 12 is movably installed in the rotating groove 11, and the shape and size of the rotating block 12 are adapted to the shape and size of the rotating groove 11. The operating block 14 is arranged on the top of the rotating block 12, and one end of the rubber stopper 13 is connected to the operating block 14. Figure 3As shown, when in use, after placing the convex mirror 7 on the upper end surface of the acquisition frame 2, manually twist the operating block 14 to rotate the rotating block 12 and the rubber stopper 13 until the bottom surface of the rubber stopper 13 away from the operating block 14 is pressed on the convex mirror 7. Similarly, the rubber stopper 13 in other convex mirror clamping assemblies is operated to press on the convex mirror 7, so that the convex mirror 7 can be installed and fixed. Without using any tools, the positions of the rubber stopper 13 in multiple convex mirror clamping assemblies can be adjusted by hand, which further realizes the rapid disassembly and replacement of the convex mirror 7, greatly improving the convenience of operation and use of the device. The rubber stopper 13 is made of rubber, which can ensure that the rubber stopper 13 has a large friction when in contact with the convex mirror 7, further ensuring the installation stability of the convex mirror 7.

[0039] A fixed magnetic block A15 is embedded at one end of the bottom of the rubber stop block 13 away from the operating block 14, and a fixed magnetic block B is embedded at the top of the convex mirror 7 at a position corresponding to the fixed magnetic block A15. When the fixed magnetic block A15 is aligned with the fixed magnetic block B, the two attract each other, which can improve the installation stability and firmness of the convex mirror 7.

[0040] The power collection component 4 is arranged in the shell of the generator body 1, and the power collection component 4 is a multimeter. When in use, the multimeter is installed in the power storage position in the shell of the generator body 1.

Specifically, if the weather is clear, the convex mirror 7 will gather light on the top of the heated aluminum plate 9, so that the temperature of the heated aluminum plate 9 increases. When its actual temperature rises to the preset temperature of the infrared temperature controller 8, the infrared temperature controller 8 transmits the relevant information to the controller 10, and the controller 10 transmits the relevant information to the remote control center through the wireless transceiver module 5, and the remote control center records and stores the clear weather and climate. At the same time, the controller 10 controls the multimeter to detect the internal power of the wind turbine at the set time every day, and transmits the detection results to the remote control center for recording and storage.

[0044] S3. Location data storage and comparison: The remote control center stores the data collected at each data collection location.
