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 development of the green and clean energy market, large-scale photovoltaic power stations, as a green new energy power station, have great development potential and have attracted much attention. Moving photovoltaic power stations to the water surface can not only save land resources, but also increase power generation, reduce water evaporation, and be easy to combine with other industries. However, most of the current floating photovoltaic mooring systems are underwater mooring systems fixed by ropes and cables, which are no longer applicable in harsh application scenarios such as the ocean or inland pumped storage power station reservoir area with high water level differences. When the water level fluctuates violently, the mooring rope cannot adjust itself to adapt to the water level changes and meet the stability requirements of the photovoltaic platform. When the water level rises, the mooring rope cannot be extended due to its fixed length, causing the photovoltaic to be submerged by the water flow. When the water level drops, the mooring rope is too long, which will cause the photovoltaic to drift with the flow, seriously affecting the normal use of the floating photovoltaic power station. Therefore, improving the stability of the floating photovoltaic mooring system under high water level differences can greatly expand the application scenarios of floating photovoltaic power stations, which is of great significance to the optimization of the use performance and efficiency of floating photovoltaic power stations and the realization of the dual carbon goals.

[0003] At present, the devices and methods for the mooring system of floating photovoltaic power stations include: a Chinese invention application with 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 changing 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, and each mooring unit provides an outward pulling force to the periphery of the floating photovoltaic platform in multiple directions to flexibly unfold it. However, the invention relies on the mooring system to move with the waves to stabilize the floating photovoltaic, and does not consider the impact of drastic changes in the mooring rope caused by water level changes in extremely harsh conditions such as high water level differences. A Chinese patent application with application number CN202211210628.5 discloses a floating photovoltaic mooring system that is adaptive to high water level changes. The system consists of a fixed cable, a collar, a pile frame group, and a transformer box platform. The collar is installed in the frame group, and the two ends of the cable are respectively connected to the collar and the photovoltaic array. When the water level changes, the collar 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 costly and has great limitations. Moreover, it only limits the up and down reciprocating movement of the photovoltaics with the pile frame group, and cannot achieve fully adaptive system control. A 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 ropes along the middle area of ​​the side length of the array is connected to the underwater anchor. The steel wire ropes within 1 / 4 of the four corners of the array are connected to a spring device, and the other end of the spring device is connected to the anchor on the bottom of the pond. This 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 environments. 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 follow-up 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 graded real-time autonomous regulation according to the change of rope force. The 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 deployment of the floating photovoltaic mooring system as the water level changes, so that the entire photovoltaic system always maintains stable operation.

[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:

[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 in conjunction with specific examples.

[0070] Embodiment 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 rope according to the water level data;

[0074] S3. Control the retracting and releasing unit to retract and release the mooring rope according to the calculated retracting and releasing length of the mooring rope. The calculation formula of the retracting and releasing 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, collecting the mooring rope force after the completion of the retracting and releasing, when the rope force is less than the lower threshold, the retracting and releasing unit is started to retract the rope, and when the rope force is greater than the upper threshold, the retracting and releasing unit is started to release the rope;

[0079] In the process of collecting the mooring rope force, the wave force on the long and short sides of the floating body is 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 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 0.46; λ is 0.5m; 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 through the wave distribution model based on wave statistical data, and is 0.1m in this embodiment; A x , A y They are the lateral and longitudinal 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] Among them, H is the wave height and σ is the scale parameter of the wave height.

[0089] If the wave height is assumed to follow the 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 "Classification and Construction Specifications for 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 projection area of ​​the calculation component (i.e. the 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 0.133 for example.

[0099] According to 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 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 cable; F is the resultant force acting on a single cable, which is the mooring cable 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 with the adaptive control system turned on is shown in Fig. 9 As shown. Figure 8 , Fig. 9 It can be seen that the motor position reciprocates around the average value, which means that the motor automatically starts and stops with the action of waves, that is, the motor adaptively retracts and releases 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] The storage medium may be an electronic medium, a magnetic medium, an optical medium, an electromagnetic medium, an infrared medium, or a semiconductor system or a propagation medium. The storage medium may also include semiconductor or solid-state memory, magnetic tape, a removable computer disk, a random access memory (RAM), a read-only memory (ROM), a hard disk, and an optical disk.
