Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic mooring, and relates to a floating photovoltaic adaptive mooring system device, a control method and a readable storage medium. Background Art

[0002] With the continuous expansion of the green and clean energy market, large-scale photovoltaic power plants, as a green and renewable energy source, have attracted significant attention with their enormous development potential. Relocating photovoltaic power plants to the surface not only conserves land resources but also increases power generation, reduces water evaporation, and facilitates integration with other industries. However, current floating photovoltaic mooring systems, mostly anchored underwater with cables, are no longer suitable for harsh applications such as those in the ocean or in inland pumped-storage power plant reservoirs with high water level fluctuations. When the water level fluctuates dramatically, the mooring cables cannot autonomously adjust to the changes and meet the stability requirements of the photovoltaic platform. When the water level rises, the fixed length of the mooring cables prevents them from extending, causing the photovoltaic system to be submerged by the current. When the water level drops, excessive mooring cables can cause the photovoltaic system to drift with the current, seriously impacting the normal operation of the floating photovoltaic power station. Therefore, improving the stability of floating photovoltaic mooring systems under high water level fluctuations can greatly expand the application scenarios of floating photovoltaic power stations. This is of great significance for optimizing the performance and efficiency of floating photovoltaic power stations and contributing to the achievement of the dual carbon goals.

[0003] Currently, devices and methods for mooring systems of floating photovoltaic power stations include: Chinese invention application number CN202310167122.9 discloses an offshore floating photovoltaic system, which is composed of a pile foundation, a buoyancy assembly, a cable, and a cable redirecting component. A floating net and a buoyancy unit fixedly connected to the floating net are composed of multiple transverse cables and multiple longitudinal cables. Multiple groups of mooring units are arranged on the periphery of the photovoltaic platform. Each mooring unit provides outward pulling force to the periphery of the floating photovoltaic platform in multiple directions to flexibly unfold it. However, this invention relies on the mooring system to move with the waves to stabilize the floating photovoltaic system, and does not consider the impact of drastic changes in mooring cables caused by water level changes in extremely harsh conditions such as high water level differences. Chinese patent application number CN202211210628.5 discloses a floating photovoltaic mooring system that is adaptive to high water level changes. It consists of a fixed cable, a ring, a pile frame group, and a transformer box platform. The ring is installed in the frame group, and the two ends of the cable are respectively connected to the ring and the photovoltaic array. When the water level changes, the ring will rise or fall with the photovoltaic changes; the frame group of the above-mentioned device needs to be used with a matching pile foundation, which is expensive and has great limitations. It only limits the up and down reciprocating movement of the photovoltaic with the pile frame group, and cannot achieve fully adaptive system control. The Chinese patent application with application number CN202021396517.4 discloses a flexible mooring system for a floating photovoltaic power station on the water surface. The floating body is connected by steel wire ropes. The other section of the steel wire rope along the middle area of ​​the array side is connected to the underwater anchor. The steel wire rope within 1 / 4 of the four corners of the array is connected to a spring device, and the other end of the spring device is connected to the anchor on the bottom of the pond. It effectively solves the problem of cable breakage and connection node damage in the four corners due to uneven overall force on the array under the influence of complex environment. However, the invention does not take into account that the mooring rope will change with the water level, and cannot achieve adaptive regulation of the mooring rope. The Chinese patent application with application number CN202111250956.3 discloses a photovoltaic floating power station follower device and its working method, which consists of a water level monitoring device, a computer, a wireless signal transmitting system, a wireless signal receiving system, a fixed rope, an automatic retraction device and a traction fixed pile. One end of the fixed rope is connected to the traction fixed pile, and the other end is connected to the automatic retraction device. The rope is retracted and released according to the water level information. However, this device can only achieve unchanged rope tension when the water level rises and falls, and cannot achieve step-by-step and real-time autonomous regulation according to the change of rope tension. Its implementation method is relatively difficult and not easy to operate. Summary of the Invention

[0004] The purpose of the present invention is to provide a floating photovoltaic adaptive mooring system device, a control method and a readable storage medium, which can realize the adaptive retraction and extension of the floating photovoltaic mooring system as the water level changes, so that the entire photovoltaic system always maintains stable operation.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] In a first aspect, the present invention provides a floating photovoltaic adaptive mooring system device, comprising:

[0007] The floating mechanism includes a floating unit and a photovoltaic assembly mounted on the floating unit. The floating unit is composed of two oppositely arranged walkway floats, two oppositely arranged combiner box floats, and an anchoring truss fixedly connecting the walkway floats and the combiner box floats. A plurality of parallel connecting rods are also provided between the two walkway floats.

[0008] The mooring mechanism includes a retractable unit arranged on an anchoring truss next to one end of the walkway float, an underwater anchor preset at the bottom of the water and equipped with a guide, a guide pulley block installed on the walkway float, and a mooring rope. One end of the mooring rope is fixedly connected to the anchoring truss at the other end of the walkway float, and the other end alternately passes through the guide on the underwater anchor and the guide pulley block in sequence, and is retracted and extended through the retractable unit.

[0009] Furthermore, the walkway float and the connecting rod, and the combiner box float and the connecting rod are fixed respectively by connecting nuts.

[0010] Furthermore, a matching front bracket and a V-shaped bracket are fixed on the connecting rod between the two walkway floats. The lower end of the photovoltaic module is installed on the top of the front bracket, and the higher end is installed on the top anchoring end of the V-shaped bracket.

[0011] Furthermore, the walkway float is assembled by connecting a plurality of float sections in sequence via float connecting plates.

[0012] Furthermore, the guide member on the underwater anchor is divided into a guide ring and a double pulley assembly, and the double pulley assembly is used to guide the mooring rope to turn smoothly.

[0013] Furthermore, the double pulley assembly includes a horizontal pulley arranged longitudinally on the underwater anchor, a lateral support plate vertically installed on the underwater anchor, and a vertical pulley arranged on the lateral support plate.

[0014] Furthermore, the guide pulley assembly includes a fixed base plate installed on the walkway float, a horizontal rotating support located on the fixed base plate and rotating horizontally, a vertical rotating support arranged on the horizontal rotating support and capable of rotating inward in the vertical reverse direction, and a single pulley installed on the vertical rotating support and for the mooring rope to pass through.

[0015] In a second aspect, the present invention further provides a method for controlling a floating photovoltaic adaptive mooring system device, comprising the following steps:

[0016] S1. Obtaining water level data information of the current floating photovoltaic adaptive mooring system device;

[0017] S2. Calculate the length of the mooring line according to the water level data;

[0018] S3. Controlling the retracting and extending unit to retract and extend the mooring rope according to the calculated retracted and extended length of the mooring rope;

[0019] S4. Collect the mooring rope force after the mooring rope is retracted and released. When the rope force is less than the lower threshold, the retracting and releasing unit is activated to retract the rope. When the rope force is greater than the upper threshold, the retracting and releasing unit is activated to release the rope.

[0020] S5. When the water level signal is updated, repeat steps S2 to S4.

[0021] Furthermore, the water level data information refers to the current water level of the photovoltaic system, which can be monitored by water level measuring equipment such as radar water level gauges.

[0022] Furthermore, in S2, the calculation formula for the mooring line retraction and release length is as follows:

[0023]

[0024] S=L max -L min ,

[0025] Among them, L max is the maximum length of the mooring line at the highest water level; L min is the maximum length of the mooring line at the lowest water level; L d It is the horizontal length between the preset anchor point on the underwater anchor and the guide pulley block or anchor truss on the floating mechanism; L w is the water level; l is the vertical projection distance between the preset anchor point on the underwater anchor and the guide pulley block or anchor truss on the floating mechanism; S is the maximum length of the mooring rope.

[0026] In a third aspect, the present invention further provides a computer-readable storage medium storing a computer program, which, when executed by a processor, implements the steps of the control method of the floating photovoltaic adaptive mooring system device as described above.

[0027] Compared with the prior art, the present invention has the following advantages:

[0028] 1. The present invention uses a water level calculation method based on the mooring rope retraction and extension length to monitor changes in water level or mooring rope tension. The analysis system intervenes to determine the mooring rope retraction and extension method and calculate the retraction and extension length. After the determination is completed, the control system controls the servo motor system to retract and extend the mooring rope, realizing adaptive retraction and extension of the floating photovoltaic mooring system as the water level changes, so that the entire photovoltaic system always maintains stable operation.

[0029] 2. Based on the working characteristics of the floating photovoltaic power station mooring system, the present invention improves the mooring rope connection method and invents anchoring connection devices such as a double pulley anchoring device and a universal pulley assembly. This realizes the unobstructed continuous arrangement of the mooring ropes, improves the smoothness of the mooring connection system, and its modular assembly method is more operational.

[0030] 3. Through the coordinated anchoring method of mooring system and floating system, a small number of underwater anchors are arranged, and combined with the adaptive mooring control system, the overall structural stability of the floating photovoltaic is enhanced, greatly reducing the project cost.

[0031] 4. The technical solution of the present invention can be applied to harsh application scenarios such as ocean floating photovoltaic power stations with strong waves and the water surface of pumped storage power station reservoirs with high water level differences, and has a wide range of applications.

For example, Figure 6 As shown, the front bracket 16 is a fixed block with an angled top, which can provide an angle for fixing the photovoltaic module 17 and make it smoothly connected. Similarly, the bottom, sides and sides of the V-shaped bracket 15 are fixed with spaces, and both are flat, for connecting the photovoltaic module 17 to the floating mechanism.

[0053] In some specific embodiments, the walkway float 6 is assembled by connecting a plurality of float segments in sequence via float connecting plates 8 .

[0054] In some specific embodiments, the guide member on the underwater anchor 1 is divided into a guide ring 2 and a double pulley assembly 3, and the double pulley assembly 3 is used to guide the mooring rope 4 to smoothly turn.

[0058] In some specific embodiments, two sets of the retracting and deploying unit 5, the mooring rope 4, the matching underwater anchor 1, the guide pulley assembly 11, etc. are provided, respectively located in areas such as the two walkway floats 6.

[0059] In addition, based on the above mooring system device, the present invention also provides a control method for a floating photovoltaic adaptive mooring system device, comprising the following steps:

[0060] S1. Obtaining the water level data of the current floating photovoltaic adaptive mooring system device; S2. Calculating the retracted and extended length of the mooring rope 4 based on the water level data;

[0061] S3, controlling the retracting and extending unit 5 to retract and extend the mooring rope 4 according to the calculated retracted and extended length;

[0068] The above embodiments may be implemented individually or in any combination of two or more.

[0069] The above implementation is described in more detail below with reference to specific examples.

[0070] Example 1:

[0071] Based on the mooring system device mentioned in the above embodiment, this embodiment provides a control method for a floating photovoltaic adaptive mooring system device, see Figures 7 to 9 As shown, the following steps are included:

[0072] S1. Obtaining water level data information of the current floating photovoltaic adaptive mooring system device;

[0073] S2. Calculate the length of the mooring line according to the water level data;

[0074] S3. Control the retracting and extending unit to retract and extend the mooring rope according to the calculated retracted and extended length of the mooring rope. The calculation formula for the retracted and extended length of the mooring rope is as follows:

[0075]

[0076] S=L max -L min (3)

[0077] Among them, L max is the maximum length of the mooring line at the highest water level; L min is the maximum length of the mooring line at the lowest water level; L dIt is the horizontal length between the preset anchor point on the underwater anchor and the guide pulley block or anchor truss on the floating mechanism; L w is the water level; l is the vertical projection distance between the preset anchor point on the underwater anchor and the guide pulley block or anchor truss on the floating mechanism; S is the maximum length of the mooring rope.

[0078] S4. Collect the mooring rope force after the mooring rope is retracted and released. When the rope force is less than the lower threshold, the retracting and releasing unit is activated to retract the rope. When the rope force is greater than the upper threshold, the retracting and releasing unit is activated to release the rope.

[0079] In the process of collecting the mooring cable forces, the wave forces acting on the long and short sides of the floating body are calculated according to the wave force calculation formula. The calculation formula is as follows:

[0080] Q y =χkρghA x (4)

[0081] Q x =χkρghA y (5)

[0082] Among them, Q y , Q x They are the lateral and longitudinal components of the wave force calculated for the floating body (i.e., the floating mechanism); χ is a coefficient, which is set to 0.46; λ is set to 0.5 m; k is a coefficient, which is selected according to Table 1, where a1 is the maximum horizontal dimension of the vertical profile of the wave force of the underwater part of the floating body; h is the H5% wave height (the wave height with a guaranteed rate of 5% in the wave system), which is obtained based on wave statistical data and the wave distribution model, and is set to 0.1 m in this embodiment; A x 、A y They are the horizontal and vertical water-blocking areas of the floating body underwater (the size of the floating body remains unchanged, so its water-blocking area remains unchanged).

[0083] Table 1 Coefficient k

[0084]

[0085] In addition, the selection of the above wave distribution model depends on the characteristics of the ocean environment and the actual measurement data. The wave height is usually assumed to conform to a certain statistical distribution, the most common of which are Rayleigh distribution, Weibull distribution or normal distribution.

[0086] If the wave height is assumed to follow a Rayleigh distribution, the probability density function (PDF) of the wave height is:

[0087]

[0088] Where H is the wave height and σ is the scale parameter of the wave height.

[0089] If we assume that the wave height follows a Weibull distribution, its probability density function is:

[0090]

[0091] where k and λ are the shape and size parameters of the Weibull distribution.

[0092] According to the relevant provisions of JTS144-1-2010 "Standards for Loads in Port Engineering" and "Rules for Classification and Construction of Offshore Mobile Platforms" (China Classification Society, 2016), the water flow load on the floating array is calculated using the following formula:

[0093]

[0094] Among them, F cs is the water flow force; C w is the water flow resistance coefficient; ρ is the water density; v c is the water flow velocity; A is the projected area of ​​the calculation component (i.e. floating mechanism) on the vertical plane along the flow direction.

[0095] Calculate gravity load and buoyancy using the following formula:

[0096] F d =ρ p gAt (7)

[0097] F f =ρgh d (8)

[0098] Among them, F d 、F f are gravity load and buoyancy respectively; ρ p is the converted material density of the float (the density of the photovoltaic panel is considered to be consistent with the density of the float material). In this embodiment, a high-density polyethylene float is selected; A is the converted area of ​​the float and the photovoltaic panel; t is the thickness of the float; h d is the draft of the floating body, which can be taken as 0.133 for example.

[0099] Based on the above calculation results, in accordance with the relevant provisions of GB50158-2010 "Uniform Standard for Reliability Design of Port Engineering Structures" and GB50009-2012 "Code for Loads on Building Structures", the mooring cable force is calculated according to the load combination controlled by the ultimate limit state of the photovoltaic array system's bearing capacity. The calculation formula is as follows:

[0100] S d =1.2(F d +F f )+0.7(1.5F water +1.5F wave ) (9)

[0101] F c=0.7×1.5×Q y (10)

[0102] F d =0.7×1.5×Q x (11)

[0103] F y =1.2×(F d +F f ) (12)

[0104]

[0105] Among them, S d is the control load combination under the ultimate state of the photovoltaic array system's carrying capacity; F c 、F d are the horizontal long side component and the horizontal short side component of the mooring rope respectively; F y is the vertical force of the mooring rope; F is the resultant force acting on a single rope, which is the mooring rope force to be collected.

[0106] S5. When the water level signal is updated, repeat steps S2 to S4.

[0107] The process of the novel floating photovoltaic adaptive mooring system control method of this embodiment is as follows: Figure 7 As shown in the figure, according to the above process, the water level is 1.1m, the vibration frequency of the vibration table is 0.5Hz, and the mooring cable tension time history diagram without turning on the adaptive control system is as follows: Figure 8 As shown in the figure, the time history of the mooring cable tension when the adaptive control system is turned on is shown in the figure Figure 9 As shown. Figure 8 、 Figure 9 It can be seen that the motor position reciprocates around the average value, which means that under the action of waves, the motor automatically starts and stops according to the action of waves, that is, the motor adaptively retracts and extends the mooring rope, realizing a fully adaptive control function.

[0108] In some specific embodiments, the present invention further provides a computer-readable storage medium storing a computer program, which, when executed by a processor, implements the steps of the control method of the floating photovoltaic adaptive mooring system device as described above.

[0109] Storage media can be electronic, magnetic, optical, electromagnetic, infrared, or semiconductor systems or propagation media. Storage media can also include semiconductor or solid-state memory, magnetic tape, removable computer disks, random access memory (RAM), read-only memory (ROM), hard disks, and optical disks. Optical disks can include compact disk-read only memory (CD-ROM), compact disk-read / write (CD-RW), and DVD.
