Description

[0002] Research and technology on typhoon statistics, forecasting and warning have made many important progress and applications at home and abroad, but no consideration has been given to how to make full use of the huge wind energy resources brought by typhoons, thereby improving the efficiency of offshore wind power generation, and how to minimize the impact time of typhoons on offshore wind power stations during transit and landing. For example: the wind speed range of the typhoon level 8 wind circle defined by my country's meteorological department has not yet reached the cut-out wind speed of the wind turbine, and the wind turbine can still maintain efficient power generation within its influence range, while the range of the level 10 wind circle has certain dangers and needs to be warned. During the offshore wind power generation process and the typhoon transit or landing process, if the typhoon wind speed impact range can be effectively predicted in the time period of the level 8-10 wind circle, it can be shut down in time before the arrival of the level 10 wind circle, and the power generation efficiency can be improved when the level 8 wind circle arrives, thereby generating considerable power generation benefits. The existing technology for predicting the arrival time of typhoons usually directly calculates the ratio of the center distance (the distance between the typhoon center and the wind farm) and the typhoon moving speed, and cannot accurately obtain the arrival time corresponding to different wind circles.

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1 and Figure 2 In one embodiment, a typhoon arrival time prediction method comprises the following steps:

[0024] Step S101: Obtain the real-time center position and wind circle radius information of the target typhoon.

[0025] Step S102: Calculate the typhoon fullness of each level of wind circles of the target typhoon based on the wind circle radius information.

[0026] Step S103: Calculate the predicted time for each level of wind circle to reach the wind farm by combining the typhoon fullness and real-time center position of each level of wind circle.

[0027] Specifically, a typhoon arrival time prediction method for an offshore wind farm proposed in an embodiment of the present invention is based on a full study and analysis of the climate characteristics of typhoons landing on the coast of my country, and is aimed at the power generation efficiency and operation and maintenance of offshore wind farms. It not only considers the impact of wind disasters before the typhoon passes or lands, but also fully considers the considerable potential wind energy resources brought by the typhoon, and the impact of factors such as the spatial distribution of the typhoon's speed, intensity and wind circle radius on the typhoon warning. First, the center position of the wind farm is clarified, including the central longitude and latitude of the wind farm. Then, the real-time center position and wind circle radius information of the target typhoon are obtained. The real-time center position and wind circle radius information of the target typhoon can be downloaded from a public website. The real-time center position specifically includes the real-time center longitude and latitude of the typhoon, and the wind circle radius information specifically includes the radius size of each level of wind circle and the wind speed value corresponding to each level of wind circle. Taking the 8-level wind circle, the 10-level wind circle and the 12-level wind circle as examples, the radius of the 8-level wind circle is R8 with a wind speed of 17m / s, the radius of the 10-level wind circle is R10 with a wind speed of 25m / s, and the radius of the 12-level wind circle is R12 with a wind speed of 32m / s. Typhoon fullness is an indicator proposed in 2018 for characterizing the intensity of a typhoon. The concept of typhoon fullness is defined as "the width of the ring formed between the outer wind circle and the inner core, and the proportion of the outer wind circle". The larger this proportion, the stronger the typhoon. Based on this, the embodiment of the present invention calculates the typhoon fullness of wind circles at all levels through the acquired wind circle radius information, and introduces the typhoon fullness of wind circles at all levels into the time prediction algorithm. When the typhoon intensity is greater and the scale is larger, the disaster impact of the typhoon may also be greater, which has a certain impact on the moving speed of the typhoon (the moving speed of the typhoon refers to the theoretical average speed of the typhoon from one location to another). The stronger the typhoon, the shorter the remaining warning time. The typhoon richness is used to optimize the time prediction algorithm, and then the predicted time for wind circles at all levels to reach the wind farm is calculated, which improves the accuracy of the predicted time for wind circles at all levels to reach the wind farm.

[0028] Specifically, in one embodiment, before the above step S102, the following steps are also included:

[0029] Step 1: Draw the optimal path of the target typhoon based on the real-time center position, and determine the impact range of the target typhoon through the optimal path and wind circle radius information.

[0030] Step 2: Determine whether the wind farm falls within the influence range. If the wind farm falls within the influence range, calculate the typhoon fullness of each level of wind circles of the target typhoon based on the wind circle radius information.

[0031] Specifically, before making a time prediction, the movement trend of the typhoon is obtained based on the real-time center position of the target typhoon, so as to draw the best path for the target typhoon. Then, the radius information of the wind circle is combined on the best path to determine the total impact range that the path can expand to. It is determined whether the longitude and latitude coordinates of the wind farm fall within the impact range. If it falls within the impact range, the arrival time of each level of wind circle is predicted, otherwise no prediction is made to improve the efficiency of the time prediction algorithm.

[0032] Specifically, in one embodiment, the above step S102 specifically includes the following steps:

[0033] Step 3: Extract the outer wind speed of the current wind circle and the typhoon center wind speed from the wind circle radius information.

[0034] Step 4: Calculate the typhoon fullness of the current wind circle based on the ratio of the outer wind speed of the current wind circle to the wind speed at the center of the typhoon.

[0035] Specifically, the concept of each level of wind circle is actually defined by the peripheral wind speed of each level of wind circle. For example, the wind speed of a level 8 wind circle is 34 km / h. No matter how the radius length changes, the position that meets the wind speed condition can be regarded as a level 8 wind circle. Therefore, in this embodiment, the range of the wind circle is characterized by the peripheral wind speed corresponding to each wind circle, and the typhoon fullness of each level of wind circle is calculated based on the ratio of the wind speed of the wind circle and the wind speed of the typhoon center, instead of directly using the radius length to calculate the range of the wind circle, so it is more in line with the definition and more accurate than the calculation method using the radius length.

[0036] In this embodiment, the expression for calculating the typhoon richness is as follows:

[0037]

[0038] In the formula, 1, 0.65 and -1.16 have no clear physical meanings. The above parameters are determined by statistical analysis of linear fitting of all typhoons in history. R is a constant, i.e. the peripheral wind speed of each level of wind circle; V max is the typhoon intensity, which is the maximum wind speed in the typhoon center.

[0039] Specifically, in one embodiment, the above step S103 specifically includes the following steps:

[0040] Step 5: Extract the current wind circle radius of the current wind circle from the wind circle radius information.

[0041] Step 6: Determine the moving distance based on the difference between the center distance and the current wind circle radius. The center distance is the distance between the typhoon center and the wind farm determined by the real-time center position.

[0042] Step 7: Calculate the typhoon moving speed based on the real-time center position.

[0043] Step 8: Calculate the predicted time for the current wind circle to reach the wind farm based on the moving distance, the typhoon richness of the current wind circle and the typhoon moving speed.

[0044] Specifically, in this embodiment, before calculating the predicted time for the wind circles at various levels to arrive at the wind farm, the distance between the edge of the wind circles at various levels and the wind farm position is first determined, that is, the moving distance that the wind circles at various levels need to move is determined. This embodiment extracts the specific values ​​of the radii of the wind circles at various levels from the wind circle radius information, such as R8, R10, and R12, and then calculates the difference between the center distance (center distance = the distance between the wind farm coordinates and the typhoon center coordinates) and the radii of the wind circles at various levels, and thus obtains the distance between the edge of the wind circles at various levels and the wind farm position. Then, based on the downloaded multiple real-time center positions and the time interval between the implementation center positions, the average speed of the typhoon movement can be calculated as the moving speed of the typhoon movement. Finally, the typhoon mobility is optimized using the typhoon fullness, and then a more accurate predicted time for the wind circles at various levels to arrive at the wind farm is calculated based on the algorithm of "distance / optimized speed = time".

[0045] Specifically, in this embodiment, the method for optimizing the typhoon moving speed by the typhoon fullness of each wind circle is to directly calculate the product of the typhoon fullness of each wind circle and the typhoon moving speed. Based on this, the formula for calculating the predicted time of each wind circle reaching the wind farm is as follows:

[0046]

[0047] Where, T is the warning time (h); D is the center distance calculated in real time (km); R is the radius of the wind circle; V R is a constant, the wind speed outside the wind circle; V max is the typhoon intensity, that is, the maximum wind speed in the typhoon center (km / h); Vs is the typhoon moving speed.

[0048] Based on the above steps 5 to 8, the typhoon movement speed, the maximum wind speed in the center and the distance to a single offshore wind power station are organically combined, and the distances calculated from wind circles of different wind force levels to a single offshore wind power station are also different accordingly. The smaller the distance, the greater the impact of the typhoon on the wind power station. The faster the typhoon moves, the shorter the warning time affected by the radius range of wind circles at all levels. Finally, the calculation of the warning time also incorporates the power function relationship between the typhoon's fullness and intensity, in order to reflect the connection between typhoons of different intensities and their own scales, thereby optimizing the movement speed of the typhoon.

[0049] Specifically, in one embodiment, before the above step S102, the following steps are also included:

[0050] Step 9: Perform outlier analysis on the acquired real-time center position and wind circle radius information to eliminate the sudden change data.

[0051] Specifically, in this embodiment, outlier analysis is also performed on the data in the downloaded real-time center position and wind circle radius information, and according to the trend of the data, data with larger mutations in adjacent data are found. For example, the difference between a certain data and adjacent data exceeds a preset threshold, and the mutation data is then eliminated to further improve the accuracy of subsequent typhoon arrival time predictions.

[0052] Specifically, in one embodiment, a typhoon arrival time prediction method provided by an embodiment of the present invention further includes the following steps:

[0053] Step 10: Display the predicted time for the current wind circles of each level to reach the wind farm, and return to the step of obtaining the real-time center position and wind circle radius information of the target typhoon for the next round of prediction.

[0054] Step 11: When a new predicted time for each level of wind circle to arrive at the wind farm is generated, the new predicted time for each level of wind circle to arrive at the wind farm is used to replace the current predicted time for each level of wind circle to arrive at the wind farm.

[0055] Specifically, in this embodiment, after calculating the predicted time for the current wind circles at all levels to arrive at the wind farm, the current electronic device immediately enters the next round of prediction. To avoid changes in the predicted time due to the uncertainty of the typhoon, the arrival time of the typhoon wind circles at all levels is corrected in real time, and the corrected value is sent to the display platform for display. On the one hand, meteorological personnel can obtain the forecast data in a timely manner, and on the other hand, the control system of the wind farm can adjust the control strategy of the wind farm shutdown in time according to the latest forecast time, realize accurate shutdown and accurate startup, and achieve the maximum efficiency of wind energy generation under the premise of ensuring safety.

[0056] Through the above steps, the technical solution provided by the present application first obtains the real-time center position and wind circle radius information of the target typhoon, and then calculates the typhoon fullness of each wind circle of the target typhoon based on the radii of each wind circle at each level in the wind circle radius information or the wind speed corresponding to the radii of each wind circle at each level; finally, the typhoon fullness that characterizes the typhoon intensity is introduced into the distance / speed time algorithm, and the typhoon fullness and real-time center position of each wind circle are combined to calculate the predicted time for each wind circle to arrive at the wind farm, which not only realizes the time prediction of each wind circle arriving at the wind farm, but also improves the accuracy of the predicted time for each wind circle to arrive at the wind farm. In addition, when calculating the typhoon fullness of each wind circle, the embodiment of the present invention is based on the ratio of the wind speed corresponding to each wind circle and the wind speed at the center of the typhoon, thereby improving the accuracy of the typhoon fullness.
