Description

Technical Field

[0001] The present invention relates to the technical field of offshore wind power operation and maintenance, and in particular to a scheduling method for an offshore wind power operation and maintenance platform constructed by high-performance ships. Background Art

[0002] Offshore wind power has the characteristics and advantages of unmanned operation, 24-hour automatic operation and onshore remote monitoring. However, due to the influence of multiple factors such as the widespread dispersion of offshore wind power, the changing sea conditions at sea and the single existing operation and maintenance vessels, the operation and maintenance costs of offshore wind power in existing technologies are very high.

[0003] Existing operation and maintenance ships are basically traditional ships, which cannot sail when complex sea conditions occur, resulting in untimely and inaccessible wind power maintenance. Even if they are forced to sail, there is a high potential risk of damage to ships, equipment, and even casualties. In addition, the existing technology is unable to effectively and reliably coordinate and dispatch between multiple ships and wind power operation and maintenance, and there is also the problem of low ship utilization efficiency. Summary of the Invention

[0004] In response to the shortcomings of the above-mentioned existing production technologies, the applicant provides a scheduling method for an offshore wind power operation and maintenance platform with a rational structure constructed by high-performance ships, thereby constructing an offshore wind power operation and maintenance platform that integrates operation and maintenance information collection, control and command, and can quickly plan operation and maintenance scheduling, greatly improving the utilization rate of ships and reducing operation and maintenance costs.

[0005] The technical solutions adopted in the present invention are as follows:

[0006] A scheduling method for an offshore wind power operation and maintenance platform constructed with high-performance ships, wherein the types of operation and maintenance ships in the offshore wind power operation and maintenance platform include catamaran mother ships, catamaran daughter ships, and channel boats;

[0007] The scheduling method comprises the following steps:

[0008] Step 1: The catamaran mother ship in the offshore wind power operation and maintenance platform is used as the control center, which receives the operation and maintenance ship status and location information and wind turbine fault and location information in real time;

[0009] Step 2: Obtain the payload required for operation and maintenance based on the wind turbine fault analysis, and obtain the real-time maintenance distance L between the operation and maintenance ship and the wind turbine based on the operation and maintenance ship position, wind turbine position, and catamaran mother ship position. cf , the return distance L between the return destination and the wind turbine df ;

[0010] Step 3: The catamaran mother ship analyzes and obtains the type of operation and maintenance vessel that has priority for departure based on wave height and payload information;

[0011] Step 4: Obtain the remaining fuel of all ships involved in the priority operation and maintenance ship type, and obtain the actual voyage S of the corresponding ship from the remaining fuel c ;

[0012] Step 5: Convert the actual distance S in step 4 to c The maintenance distance L in step 2 cf , return distance L df Perform calculations and analysis to ensure that the corresponding vessel can return to the preset return destination after maintaining the faulty wind turbine, so as to select the vessel for sailing and maintenance.

[0013] Step 6: If the type of maintenance vessel with priority for departure obtained in step 3 is a trough boat or a catamaran daughter ship, and all ships of the corresponding maintenance vessel type cannot return to the preset return destination after the calculation and analysis in step 5, the maintenance vessel type with priority for departure will be upgraded, including upgrading the trough boat to a catamaran daughter ship and upgrading the catamaran daughter ship to a catamaran mother ship, and repeating steps 4 to 6; if the type of maintenance vessel with priority for departure is already a catamaran mother ship, and the catamaran mother ship cannot return to the preset return destination after the calculation and analysis in step 5, maintenance scheduling cannot be carried out, and the catamaran mother ship will report to the ground control center.

[0014] As a further improvement of the above technical solution:

[0015] In step three, when analyzing and obtaining the type of operation and maintenance ship with priority for departure, if any of the following conditions is met: wave height > mother ship wave height H1, or payload > mother ship load G1, operation and maintenance scheduling cannot be carried out, and the catamaran mother ship will report the wind turbine failure to the ground control center; if the wave height is below the mother ship wave height H1, and the payload is below the mother ship load G1, the catamaran mother ship will carry out operation and maintenance planning to obtain the type of operation and maintenance ship with priority for departure; the mother ship wave height H1 is the extreme wave height of the catamaran mother ship, and the mother ship load G1 is the extreme payload of the catamaran mother ship.

[0016] The catamaran mother ship has a maximum wave height of 3 meters and a maximum payload of 800 tons.

[0017] The specific steps for operation and maintenance planning by the catamaran mother ship are:

[0018] Step 1: When the payload ≥ daughter ship load G2 and the wave height ≥ daughter ship wave height H2, if either of the two parameter conditions is met, the catamaran mother ship is the priority type of operation and maintenance ship for sailing; the daughter ship load G2 and the daughter ship wave height H2 are the maximum payload and maximum wave height of a single catamaran daughter ship respectively;

[0019] Step 2: When the payload is within the range of boat load G3 - daughter ship load G2, and the wave height is less than the daughter ship wave height H2, the catamaran daughter ship is the priority type of operation and maintenance ship for sailing; the boat load G3 is the maximum payload of a single channel boat;

[0020] Step 3: When the effective load is less than the boat load G3, if the wave height is within the range of boat wave height H3 - daughter ship wave height H2, the catamaran daughter ship will be the priority type of operation and maintenance ship for sailing. If the wave height is less than the boat wave height H3, the channel boat will be the priority type of operation and maintenance ship for sailing. The boat wave height H3 is the maximum wave height for a single channel boat.

[0021] Complete the determination of the types of maintenance vessels that have priority for departure.

[0022] The ultimate payload of the catamaran daughter ship is 30 tons, and the ultimate wave height is 2.5 meters; the ultimate payload of the channel boat is 1.4 tons, and the ultimate wave height is 1.25 meters.

[0023] For the catamaran mother ship, the return destination is the ground control center; for the catamaran daughter ship and channel boat, the return destination is the catamaran mother ship.

[0024] The offshore wind power operation and maintenance platform includes a catamaran mother ship and is equipped with four catamaran daughter ships; the catamaran mother ship supplies the catamaran daughter ships, and the channel boat is hoisted onto the corresponding catamaran daughter ship or the catamaran mother ship.

[0025] In step 5, when the actual range S c , Maintenance distance L cf , return distance L df When the following relationship is met:

[0026] S c ≥ 2 L cf +L df ;

[0027] Determine whether the corresponding ship can return to the preset return destination.

[0028] Among the types of maintenance ships that have priority for sailing, those that meet the actual voyage S c , Maintenance distance L cf , return distance L df The corresponding number of ships in the relationship is zero, one, or more than two.

[0029] The beneficial effects of the present invention are as follows:

[0030] The present invention has a compact and reasonable structure and is easy to operate. It is stationed at a preset position at sea with a catamaran mother ship as the center, and is combined with multiple catamaran daughter ships and channel boats to form an offshore wind power operation and maintenance platform. It integrates operation and maintenance information collection, control and command, and has all-weather and all-regional operation and maintenance capabilities as well as smooth logistics and warehousing capabilities, meeting the needs of close-range, rapid emergency response and inspection and maintenance. Based on real-time information parameters, the offshore wind power operation and maintenance platform can quickly plan and dispatch operation and maintenance, so as to accurately and timely operate and maintain faulty wind turbines, greatly improving the utilization rate of ships and reducing operation and maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Figure 1 Schematic diagram of the flow of the scheduling method of the present invention. DETAILED DESCRIPTION

[0032] The specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0033] like Figure 1 As shown, this embodiment provides a scheduling method for an offshore wind power operation and maintenance platform constructed by high-performance ships. The types of operation and maintenance ships in the offshore wind power operation and maintenance platform include catamaran mother ships, catamaran daughter ships, and channel boats.

[0034] The scheduling method includes the following steps:

[0035] Step 1: The catamaran mother ship in the offshore wind power operation and maintenance platform is used as the control center, which receives the operation and maintenance ship status and location information and wind turbine fault and location information in real time;

[0036] Step 2: Obtain the payload required for operation and maintenance based on the wind turbine fault analysis, and obtain the real-time maintenance distance L between the operation and maintenance ship and the wind turbine based on the operation and maintenance ship position, wind turbine position, and catamaran mother ship position. cf , the return distance L between the return destination and the wind turbine df ;

[0037] Step 3: The catamaran mother ship analyzes and obtains the type of operation and maintenance vessel that has priority for departure based on wave height and payload information;

[0038] In the analysis of obtaining the type of operation and maintenance vessel with priority for departure, if any of the following conditions is met: wave height > mother ship wave height H1, or payload > mother ship load G1, operation and maintenance scheduling cannot be carried out, and the catamaran mother ship will report the wind turbine failure to the ground control center; if the wave height is below the mother ship wave height H1, and the payload is below the mother ship load G1, the catamaran mother ship will carry out operation and maintenance planning to obtain the type of operation and maintenance vessel with priority for departure; the mother ship wave height H1 is the extreme wave height of the catamaran mother ship, and the mother ship load G1 is the extreme payload of the catamaran mother ship.

[0039] The specific steps for operation and maintenance planning by the catamaran mother ship are:

[0040] Step 1: When the payload ≥ daughter ship load G2 and the wave height ≥ daughter ship wave height H2, if either of the two parameter conditions is met, the catamaran mother ship is the priority type of operation and maintenance ship for sailing; the daughter ship load G2 and the daughter ship wave height H2 are the maximum payload and maximum wave height of a single catamaran daughter ship respectively;

[0041] Step 2: When the payload is within the range of boat load G3 - daughter ship load G2, and the wave height is less than the daughter ship wave height H2, the catamaran daughter ship is the priority type of operation and maintenance ship for sailing; the boat load G3 is the maximum payload of a single channel boat;

[0042] Step 3: When the effective load is less than the boat load G3, if the wave height is within the range of boat wave height H3 - daughter ship wave height H2, the catamaran daughter ship will be the priority type of operation and maintenance ship for sailing. If the wave height is less than the boat wave height H3, the channel boat will be the priority type of operation and maintenance ship for sailing. The boat wave height H3 is the maximum wave height for a single channel boat.

[0043] Complete the determination of the types of maintenance vessels that have priority for departure.

[0044] Step 4: Obtain the remaining fuel of all ships involved in the priority operation and maintenance ship type, and obtain the actual voyage S of the corresponding ship from the remaining fuel c ;

[0045] Step 5: Convert the actual distance S in step 4 to c The maintenance distance L in step 2 cf , return distance L df Perform calculations and analysis to ensure that the corresponding vessel can return to the preset return destination after maintaining the faulty wind turbine, so as to select the vessel for sailing and maintenance.

[0046] When the actual voyage S c , Maintenance distance L cf , return distance L df When the following relationship is met:

[0047] S c ≥ 2 L cf +L df ;

[0048] Determine whether the corresponding ship can return to the preset return destination.

[0049] Among the types of maintenance ships that have priority for sailing, those that meet the actual voyage S c , Maintenance distance L cf , return distance L df The corresponding number of ships in the relationship is zero, one, or more than two.

[0050] Step 6: If the type of maintenance vessel with priority for departure obtained in step 3 is a trough boat or a catamaran daughter ship, and all ships of the corresponding maintenance vessel type cannot return to the preset return destination after calculation and analysis in step 5, that is, the number is zero, then the maintenance vessel type with priority for departure will be upgraded, including upgrading the trough boat to a catamaran daughter ship, and upgrading the catamaran daughter ship to a catamaran mother ship, and repeating steps 4 to 6; if the maintenance vessel type with priority for departure is already a catamaran mother ship, and the catamaran mother ship cannot return to the preset return destination after calculation and analysis in step 5, then maintenance scheduling cannot be carried out, and the catamaran mother ship will report to the ground control center.

[0051] In step 5, among the types of maintenance ships that have priority for sailing, the ones that meet the actual voyage S c , Maintenance distance L cf , return distance L df When the number of ships corresponding to the relationship is zero, the type of operation and maintenance ship is upgraded according to step 6 or the operation and maintenance scheduling cannot be performed; when the number of ships corresponding to the relationship is one, the ship is the selected operation and maintenance ship for sailing; when the number of ships corresponding to the relationship is two or more, any one of the ships can be selected as the operation and maintenance ship for sailing.

[0052] For catamaran mother ship, catamaran daughter ship and channel boat, the specific indicators are as follows:

[0053]

[0054] As shown in the above table:

[0055] The technical specifications of the 3-ton channel boat are: high-speed navigation in sea state level 3, safe navigation in sea state level 4, and a cruising range of 200 nautical miles. The channel boat is within the offshore operation restrictions stipulated by the China Classification Society (CCS). The maximum payload of the channel boat is 1.4 tons and the maximum wave height is 1.25 meters.

[0056] The 330-ton SWATH maintenance vessel (catamaran daughter vessel) has the following technical specifications: suitable for offshore navigation, safe navigation in sea state level 4, and a cruising range of 500 nautical miles. The SWATH daughter vessel falls within the offshore operating limits specified by the China Classification Society (CCS), with a maximum payload of 30 tons and a maximum wave height of 2.5 meters.

[0057] The technical indicators of the 4,000-ton small waterplane area catamaran operation and maintenance vessel (catamaran mother ship) are: to provide operation and maintenance services for offshore wind turbines in the South China Sea within 200 nautical miles beyond 60 nautical miles, to have the ability to operate normally in level 5 sea conditions and to meet the requirements of safe navigation in level 7 sea conditions, with a cruising range of more than 5,000 nautical miles and a self-sustaining capacity of more than 30 days; the catamaran mother ship has a maximum wave height of 3 meters and a maximum payload of 800 tons.

[0058] As shown in the table above, the cruising range of the catamaran mother ship is 12038 kilometers. When the wind turbine fault information is obtained at the center of the mother ship, if the position of the faulty wind turbine is relative to the catamaran mother ship, the 2L cf +L df When the range information obtained is greater than its maximum endurance of 12,000 kilometers, it can be directly determined that the wind power operation and maintenance platform is unable to operate and maintain the faulty wind turbine, and needs to report it to the ground control center.

[0059] In working mode, the catamaran mother ship is stationed at a preset position at sea, and the return destination of the catamaran mother ship is the ground control center. For the catamaran daughter ship and channel boat, the return destination is the catamaran mother ship.

[0060] The offshore wind power operation and maintenance platform includes a catamaran mother ship, equipped with four catamaran daughter ships, and several channel boats; the catamaran mother ship supplies the catamaran daughter ships, and the channel boats are hoisted onto the corresponding catamaran daughter ships or catamaran mother ship.

[0061] When the catamaran mother ship is anchored and positioned, four catamaran daughter ships can be fastened, and the catamaran mother ship can supply the catamaran daughter ships.

[0062] In the present invention, a catamaran mother ship is stationed at a preset position at sea, and a plurality of catamaran daughter ships and channel boats are combined to form an offshore wind power operation and maintenance platform, which integrates operation and maintenance information collection, control and command. It has all-weather and all-region operation and maintenance capabilities as well as smooth logistics and warehousing capabilities, meeting the needs of close-range, rapid emergency response and inspection and maintenance, and can perform rapid planning and operation and maintenance scheduling by the offshore wind power operation and maintenance platform based on real-time information parameters.

[0063] Taking the offshore wind power operation and maintenance platform including a catamaran mother ship, four catamaran daughter ships, and four channel boats as an example, the scheduling is explained in the following operation and maintenance scenario.

[0064] Scenario 1: A faulty wind turbine requires maintenance by a vessel with a 25-ton payload, and the wave height along the maintenance route is 2 meters. Based on step 3, the vessel type that is prioritized for departure is: daughter vessel priority.

[0065] In the current real-time state, the L of the mother ship and each catamaran daughter ship cf , L df 、S c They are shown in the following table:

[0066] --- mother ship Sub-ship A Sub-ship B Sub-ship C Sub-ship D <![CDATA[L cf ]]> 100 52 70 102 245 <![CDATA[L df ]]> 466 70 125 55 180 <![CDATA[S c ]]> 10100 620 250 300 500 <![CDATA[2L cf +L df ]]> 666 174 265 259 670 <![CDATA[S c Big? ]]> yes yes no yes no

[0067] Among the four daughter ships, the actual voyage distance of daughter ship A and daughter ship C is S c , Maintenance distance L cf , return distance Ldf Satisfy the relationship S c ≥ 2 L cf +L df Therefore, in this scenario, you can choose one of the two boats A and C to go out and perform maintenance on the faulty wind turbine 1.

[0068] Scenario 2: A faulty wind turbine is located at a location requiring maintenance by a vessel with a payload of 1.1 tons. Waves along the route are 1 meter high. Based on step 3, the vessel type prioritized for departure is a channel boat.

[0069] In the current real-time state, the L of the mother ship, each catamaran daughter ship, and the channel boat cf 、L df 、S c They are shown in the following table:

[0070] --- mother ship Sub-ship A Sub-ship B Sub-ship C Sub-ship D boat a Boat b Boat boat d <![CDATA[L cf (km)]]> 200 200 60 152 80 130 65 200 35 <![CDATA[L df (km)]]> 466 70 125 55 180 150 70 180 90 <![CDATA[S c (km)]]> 10100 620 250 300 500 370 180 300 100 <![CDATA[2L cf +L df ]]> 866 470 245 359 340 410 200 580 160 <![CDATA[S c Big? ]]> yes yes yes no yes no no no no

[0071] In the four channel boats, the relationship S is not satisfied. c ≥ 2 L cf +L df Therefore, the ship type is upgraded to a catamaran sub-ship; at this time, the L of sub-ship A, sub-ship B, and sub-ship D cf 、L df 、S c Satisfy the relationship S c ≥ 2 L cf +L df , then choose one of the two routes to perform operation and maintenance on the faulty wind turbine.

[0072] Scenario 3: Wind turbine No. 3 is faulty and requires maintenance by a vessel with a 2-ton payload. The wave height along the maintenance route is 3.5 meters. According to step 3, the wave height exceeds the mother ship's wave height H1 = 3 meters, making maintenance impossible. The mother ship reports the faulty wind turbine No. 3 to the ground control center, and maintenance scheduling analysis can be conducted again after the wave height decreases and stabilizes.

[0073] Scenario 4: There are four faulty wind turbines, and a vessel with a payload of 45 tons is required for operation and maintenance. The wave height on the operation and maintenance route is 0.9 meters. According to step 3, the payload of 45 tons exceeds the daughter ship's load G2, and the catamaran mother ship is the preferred operation and maintenance ship type. If the mother ship L cf 330km, L df 500km, S c For 1900km, then 2L cf +L df is 1160km, satisfying the relationship S c ≥ 2 L cf +L df , the mother ship will operate and maintain the faulty wind turbine 4;

[0074] Scenario 5: Based on Scenario 4, if the mother ship's S c is 1000km, then the relationship S is not satisfied c ≥ 2 L cf +L df , indicating that the mother ship has insufficient oil to operate and maintain the faulty wind turbine. At this time, the mother ship reports to the ground control center and decides whether to refuel the mother ship depending on the situation.

[0075] The present invention constructs an offshore wind power operation and maintenance platform, which can perform rapid planning and operation and maintenance scheduling to accurately and promptly operate and maintain faulty wind turbines, greatly improving the utilization rate of ships and reducing operation and maintenance costs.

[0076] The above description is an explanation of the present invention, not a limitation of the present invention. The scope of the present invention is defined in the claims. Any modifications may be made within the scope of protection of the present invention.
