[0003] The present disclosure relates to the technical field of electronic equipment, and in particular to a method for controlling multiple units of an offshore floating platform. Background Art

[0004] Vertical axis wind turbines (VAWTs) are particularly well-suited for floating foundations due to their low cost, low center of gravity, and lack of yaw requirements. When combined with a floating foundation, the VAWT system eliminates the need for single-point mooring, significantly reducing the overall system cost. To maximize the utilization of floating platforms, multiple VAWTs can be installed on the same platform, thereby spreading costs and increasing power generation and revenue. However, multiple turbines also mean more risk. The inability of one or more turbines to function can compromise the stability and safety of the entire system. Summary of the Invention

[0014] The rotation speed adjustment module is used to adjust the rotation speed of the normal fans in the target fan group according to the rotation direction.

[0031] The following describes in detail embodiments of the present disclosure, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present disclosure and are not to be construed as limiting the present disclosure. On the contrary, the embodiments of the present disclosure include all variations, modifications, and equivalents that fall within the spirit and scope of the appended claims.

[0032] FIG1 is a flow chart of a multi-unit control method for an offshore floating platform according to an embodiment of the present disclosure.

[0033] It should be noted that the execution entity of the offshore floating platform multi-unit control method of this embodiment is the offshore floating platform multi-unit control device, which can be implemented by software and / or hardware. The device can be configured in a computer device, and the computer device can include but is not limited to a terminal, a server, etc. For example, the terminal can be a mobile phone, a handheld computer, etc.

[0034] As shown in FIG1 , the multi-unit control method for an offshore floating platform includes:

[0035] S101: When the number of faulty wind turbines on the offshore floating platform is less than a threshold, determine the wind turbine group to which the faulty wind turbines belong as a target wind turbine group.

[0036] The faulty wind turbine may refer to a wind turbine in an offshore floating platform that cannot operate due to a fault.

[0037] The threshold value may be a pre-configured threshold for the number of faulty wind turbines on the offshore floating platform. The specific value of this threshold value can be flexibly configured based on the total number of wind turbines on the offshore floating platform and the application scenario, and is not limited to this. For example, if the offshore floating platform has a total of 8 wind turbines, the corresponding threshold value may be 3.

[0038] The wind turbine group may refer to a group pre-divided according to the location attributes of different wind turbines in the offshore floating platform, and the target wind turbine group may refer to a group including faulty wind turbines.

[0039] In the embodiment of the present disclosure, when the number of faulty wind turbines on the offshore floating platform is less than a threshold, determining the wind turbine group to which the faulty wind turbine belongs as the target wind turbine group can provide a reliable operation object for the subsequent unit control process.

[0040] S102: Determine the rotation direction of the faulty fan in the target fan group.

[0041] The rotation direction may be, for example, counterclockwise or clockwise.

[0042] It can be understood that the target fan group may include fans with different rotation directions, and when fans with different rotation directions fail, their corresponding control adjustment processes may be different. Therefore, in the implementation of the present disclosure, when the rotation direction of the faulty fan in the target fan group is determined, reliable reference information can be provided for subsequent speed adjustment.

[0043] S103: Adjust the rotation speed of the normal fans in the target fan group according to the rotation direction.

[0044] That is, in the embodiment of the present disclosure, after determining the rotation direction of the faulty fan in the target fan group, the speed of the normal fans in the target fan group can be adjusted according to the rotation direction, thereby reducing the impact of the faulty fan on system stability.

[0045] In this embodiment, when the number of faulty wind turbines on an offshore floating platform falls below a threshold, the wind turbine group to which the faulty wind turbine belongs is identified as the target wind turbine group; the rotational direction of the faulty wind turbine in the target wind turbine group is determined; and the rotational speed of the normal wind turbines in the target wind turbine group is adjusted based on the rotational direction. This allows accurate adjustment of the rotational speed of the normal wind turbines in the target wind turbine group based on the rotational direction of the faulty wind turbine when a faulty wind turbine is present on an offshore floating platform, effectively reducing the impact of the faulty wind turbine on the system and improving system robustness, stability, and safety.

[0046] FIG2 is a flow chart of a multi-unit control method for an offshore floating platform according to another embodiment of the present disclosure.

[0047] As shown in FIG2 , the multi-unit control method of the offshore floating platform includes:

[0048] S201: When the number of faulty wind turbines on the offshore floating platform is less than a threshold, determine the wind turbine group to which the faulty wind turbines belong as a target wind turbine group.

[0049] S202: Determine the rotation direction of the faulty fan in the target fan group.

[0050] The description of S201 and S202 can be found in the above embodiments, which will not be repeated here.

[0051] S203: Determine a first number of faulty fans with a first rotation direction and a second number of faulty fans with a second rotation direction in the target fan group.

[0052] The first direction and the second direction may refer to two different rotation directions. When the first direction is clockwise, the corresponding second direction is counterclockwise; when the first direction is counterclockwise, the corresponding second direction is clockwise.

[0053] It can be understood that the values ​​of the first number and the second number may affect the specific unit control operation. Therefore, in the embodiment of the present disclosure, when determining the first number of faulty fans with a first rotation direction and a second number of faulty fans with a second rotation direction in the target fan group, a reliable execution basis can be provided for subsequent unit control.

[0054] S204: If the first number and the second number are equal, maintain the rotation speed of the normal fans in the target fan group.

[0055] It is understandable that in the implementation of the present disclosure, when the first number and the second number are equal, the faulty fan has a smaller impact on the torsional moment balance of the platform, and therefore the rotation speed of the normal fans in the target fan group can be maintained.

[0056] S205: If the first number and the second number are not equal, determining a difference between the first number and the second number, and adjusting the rotation speeds of the normal fans in the target fan group according to the difference.

[0057] It can be understood that in the implementation of the present disclosure, when the first number and the second number are not equal, the difference between the two is the main factor affecting the balance of the platform's torsional torque. Therefore, the difference between the first number and the second number can be determined, and the speed of the normal fans in the target fan group can be adjusted according to the difference.

[0058] In the embodiment of the present disclosure, when adjusting the speed of the normal fans in the target fan group according to the difference, the difference can be input into a pre-trained machine learning model to obtain the speed adjustment value of each normal fan in the target fan group, or, the speed adjustment scheme corresponding to the above difference can be determined based on a preset relationship table, and there is no limitation on this.

[0059] In some embodiments, when adjusting the speed of the normal fans in the target fan group according to the difference, the speed increase value of the normal fans in the target fan group can be determined according to the fan parameters; the maximum value of the first number and the second number is determined, and the rotation direction corresponding to the maximum value is used as the target direction; the third number of normal fans in the target fan group whose rotation direction is the same as the target direction, and the fourth number of normal fans whose rotation direction is opposite to the target direction are determined; the speed reduction value is determined according to the first number, the second number, the third number, the fourth number, and the speed increase value; the speed of the normal fans in the target fan group whose rotation direction is the same as the target direction is adjusted based on the speed increase value; the speed of the normal fans in the target fan group whose rotation direction is opposite to the target direction is adjusted based on the speed reduction value. In this way, the speed adjustment value can be accurately and quickly determined by effectively combining the rotation direction and number of the faulty fans and the normal fans in the target fan group, thereby effectively improving the reliability and practicality of the control process.

[0060] The speed increase value refers to the speed adjustment value that can be increased for normal fans in the target fan group. For example, the speed increase value can be 10% of the standard speed of the fan, and there is no restriction on this.

[0061] The target direction may refer to a direction with a larger number of faulty wind turbines in the first direction and the second direction.

[0062] For example, in the embodiment of the present disclosure, when determining the speed reduction value s based on the first number a, the second number b, the third number c, the fourth number d, and the speed increase value f, it can be based on the following formula: s = (|ab|*100% - f*c) / d

[0063] In the embodiment of the present disclosure, when the third number or the fourth number is zero, all the fans in the target fan group may be controlled to stop running.

[0064] That is, in the disclosed embodiment, after determining the rotation direction of the faulty fans in the target fan group, a first number of faulty fans in the target fan group with a first rotation direction and a second number of faulty fans in the target fan group with a second rotation direction can be determined. If the first number and the second number are equal, the rotation speed of the normal fans in the target fan group is maintained. If the first number and the second number are not equal, the difference between the first number and the second number is determined, and the rotation speed of the normal fans in the target fan group is adjusted based on the difference. Thus, corresponding control measures can be flexibly taken based on the comparison results of the first number and the second number, thereby effectively improving the adaptability of the control process to personalized application scenarios.

[0065] In this embodiment, a first number of faulty fans rotating in a first direction and a second number of faulty fans rotating in a second direction in a target fan group are determined. If the first number and the second number are equal, the rotational speed of the normal fans in the target fan group is maintained. If the first number and the second number are not equal, the difference between the first number and the second number is determined, and the rotational speed of the normal fans in the target fan group is adjusted based on the difference. Thus, corresponding control measures can be flexibly taken based on the comparison results of the first number and the second number, thereby effectively improving the adaptability of the control process to personalized application scenarios.

[0066] In some embodiments, when the number of faulty wind turbines on the offshore floating platform is greater than or equal to a threshold, all wind turbines on the offshore floating platform are controlled to shut down for maintenance.

[0067] It is understandable that when the number of faulty wind turbines on the offshore floating platform is greater than or equal to a threshold, the operating performance of the offshore floating platform may have been significantly affected, and the system stability cannot be maintained by adjusting the speed. Therefore, all wind turbines on the offshore floating platform can be controlled to be shut down for maintenance.

[0068] In some embodiments, the offshore floating platform includes: a floating foundation and a first number of vertical axis wind turbines, the floating foundation is in the shape of a U-shaped or circular ring, the first number is a multiple of 4, and the first number of vertical axis wind turbines are divided into multiple wind turbine groups.

[0069] That is, in the embodiment of the present disclosure, the floating foundation of the offshore floating platform may adopt a U-shaped or annular foundation, and a first number of vertical axis wind turbines are arranged on the floating foundation.

[0070] For example, as shown in FIG3 , FIG3 is a schematic diagram of the floating platform structure proposed in the present disclosure. In addition to the floating foundation and the vertical axis wind turbine, the floating platform may also include a cage, an anchor foundation, a mooring cable, etc., without limitation.

[0071] In some embodiments, the plurality of wind turbine groups includes at least one of the following:

[0072] The first group, wherein the first group ① includes four first wind turbines, which are wind turbines located at the corners of the U-shaped floating foundation, or wind turbines located at the four equal parts of the circular floating foundation;

[0073] The second group, wherein the second group ② includes four second fans, and the second fans are fans located in the middle position when the number of fans between two adjacent first fans is an odd number;

[0074] The third group, wherein the third group ③ includes multiple third wind turbines, and the third wind turbines are other wind turbines in the first number of vertical axis wind turbine units except the first wind turbine and the second wind turbine.

[0075] Therefore, multiple vertical axis wind turbines can be accurately divided based on the location attributes of different wind turbines, thereby providing reliable reference information for the unit control process.

[0076] In some embodiments, the number of fans rotating in the first direction and the number of fans rotating in the second direction in the fan group are equal and arranged symmetrically to the center, thereby ensuring a balanced torsional moment acting on the platform.

[0077] For example, as shown in Figures 4 to 6, Figure 4 is a schematic diagram of a common platform solution for 8 units proposed in the present disclosure, Figure 5 is a schematic diagram of a common platform solution for 12 units proposed in the present disclosure, and Figure 6 is a schematic diagram of a common platform solution for 16 units proposed in the present disclosure.

[0078] In this disclosure, the wind turbines on each floating foundation maintain force balance, ensuring that the entire array is force-balanced when a large-scale array is deployed. Depending on the scale required, various array configurations, such as 2×2 and 4×4, can be employed. Arrays are connected using flexible connections such as ropes. Figures 7 and 8 show a schematic diagram of a four-platform connection scheme proposed in this disclosure, and Figure 7 shows a schematic diagram of a 16-platform connection scheme proposed in this disclosure.

[0079] Based on the above embodiment, the control strategy for the faulty wind turbine in the present disclosure is implemented by the speed. Assuming that there are 8 wind turbines in total, the specific operation steps include:

[0080] a. If a fan ceases operation due to a fault, and the faulty fan is located in Group 1 (or Group 2), the speed of the fan in the same direction as the faulty fan in that group will increase by 10%, while the speed of the fan in the opposite direction will decrease by (100% - 10%) / 2 = 45%. (If there are 12 fans and the faulty fan is located in Group 3, the speed of the fan in the same direction will increase by 10%, while the speed of the fan in the opposite direction will decrease by (100% - 3 * 10%) / 4 = 17.5%). The speed of the other units remains unchanged.

[0081] b. If two fans are not operating due to a fault, and both fans appear in ① (or ②), and the two fans are rotating in the same direction, the other two fans in the group will be shut down. The speed of other types of units remains unchanged.

[0082] c. If two fans are not operating due to a fault, and both fans appear in ① (or ②), and the two fans are rotating in opposite directions, the speed of the unit in that category remains unchanged. The speed of the units in other categories remains unchanged.

[0083] d. When two fans are not running due to a fault, and the two fans appear in ① and ② respectively, in each category, the speed of the fan in the same direction as the faulty fan is increased by 10%, and the speed of the fan in the opposite direction is reduced by 45%.

[0084] e. If the number of faulty fans exceeds 3, all fans will be shut down and restarted after repairs are completed.

[0085] FIG9 is a schematic structural diagram of a multi-unit control device for an offshore floating platform according to an embodiment of the present disclosure.

[0086] As shown in FIG9 , the offshore floating platform multi-unit control device 90 includes:

[0087] A first determining module 901 is configured to determine, when the number of faulty wind turbines on the offshore floating platform is less than a threshold, the wind turbine group to which the faulty wind turbine belongs as a target wind turbine group;

[0088] The second determining module 902 is used to determine the rotation direction of the faulty wind turbine in the target wind turbine group;

[0089] The speed adjustment module 903 is configured to adjust the speed of the normal fans in the target fan group according to the rotation direction.

[0090] It should be noted that the aforementioned explanation of the offshore floating platform multi-unit control method is also applicable to the offshore floating platform multi-unit control device of this embodiment, and will not be repeated here.

[0091] In this embodiment, when the number of faulty wind turbines on an offshore floating platform falls below a threshold, the wind turbine group to which the faulty wind turbine belongs is identified as the target wind turbine group; the rotational direction of the faulty wind turbine in the target wind turbine group is determined; and the rotational speed of the normal wind turbines in the target wind turbine group is adjusted based on the rotational direction. This allows accurate adjustment of the rotational speed of the normal wind turbines in the target wind turbine group based on the rotational direction of the faulty wind turbine when a faulty wind turbine is present on an offshore floating platform, effectively reducing the impact of the faulty wind turbine on the system and improving system robustness, stability, and safety.
