Description

Technical Field

[0001] The invention relates to the technical field of offshore photovoltaics, in particular to an offshore photovoltaic regular wave simulation experimental device and method. Background Art

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductors to directly convert light energy into electrical energy. Photovoltaic energy, as a renewable energy source, is abundant and clean. Compared with traditional fossil fuel power generation technology, solar photovoltaic power generation technology will not pollute and damage the ecological environment, nor will it cause serious consequences of over-exploitation of energy. Offshore photovoltaics is a photovoltaic power generation technology that deploys photovoltaic modules on the sea surface. Due to the larger ocean area, better lighting conditions, and less land occupation, offshore photovoltaic technology has great advantages. Offshore photovoltaic technology can usually be divided into two categories: pile-based fixed type and floating type. If the seawater is shallow, pile-based high-rise installation can be adopted, that is, the pile-based fixed type solution. If the seawater is deep, floating installation can be adopted, that is, the floating type solution.

[0003] The floating solution can be deployed in sea areas far from the shore to avoid interfering with offshore aquaculture and other activities. However, due to the movement of waves at sea, the photovoltaic panels will constantly change their posture under different load conditions, especially the angle will constantly change, which will cause the power generation situation to change constantly. In order to fully guarantee the economic benefits of offshore photovoltaic projects, it is necessary to simulate this change. In the existing technology, the power generation of photovoltaic panels is mainly simulated by controlling the photovoltaic panels to adjust to some fixed angles according to preset rules.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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 ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] like Figures 1 to 8 As shown, an offshore photovoltaic regular wave simulation experimental device includes a wave state acquisition subsystem, a regular wave simulation subsystem, a photovoltaic simulation subsystem and an experimental control subsystem.

[0036] The wave state acquisition subsystem is used to collect the wave state data of the target sea area 1.

[0037] The regular wave simulation subsystem is used to drive the photovoltaic panel 41 to operate according to the wave state data.

[0038] The photovoltaic simulation subsystem is used to provide light energy to the photovoltaic panel 41 .

[0039] The experimental control subsystem is used to control the regular wave simulation subsystem according to the wave state data, and to obtain and process the power generation data of the photovoltaic panel 41 .

[0040] Before constructing an offshore photovoltaic project, first select a target sea area 1, then deploy a wave state acquisition subsystem in the target sea area 1, use the wave state acquisition subsystem to collect wave state data of the target sea area 1, then the experimental control subsystem generates regular wave simulation data based on the wave state data, removes the part of the wave state data that has little impact on the offshore photovoltaic system, extracts the part that has a greater impact on the offshore photovoltaic system, and converts it into regular waves, thereby forming regular wave simulation data, then the experimental control subsystem controls the regular wave simulation subsystem to act based on the regular wave simulation data, and during the action of the regular wave simulation subsystem, drives the photovoltaic panel 41 to act and changes the angle of the photovoltaic panel 41. During this process, the experimental control subsystem also controls the photovoltaic simulation subsystem to provide light energy to the photovoltaic panel 41, so that the photovoltaic panel 41 can generate electricity normally. Finally, the experimental control subsystem acquires and processes the power generation data of the photovoltaic panel 41, determines the correlation between the sea surface wave conditions and the power generation efficiency of the offshore photovoltaic system in the current target sea area 1, and judges whether it is suitable to deploy the offshore photovoltaic system in the target sea area 1, as well as the specific angle of the photovoltaic panel 41 in the offshore photovoltaic system. Because the regular wave simulation subsystem only needs to simulate regular waves, the control process is simpler and the experimental efficiency is higher.

[0041] The present invention first collects the wave state data of the target sea area 1, then adjusts the angle of the photovoltaic panel 41 in the offshore photovoltaic system according to the wave state data, and provides light energy to the photovoltaic panel 41, so as to simulate the actual power generation situation of the photovoltaic panel 41 in the target sea area 1, and fully verify whether it is suitable to deploy the photovoltaic system in the target sea area 1, as well as the specific angle of the photovoltaic panel 41 when deploying the photovoltaic system.

[0042] like Figure 1As shown, considering that the wave state of the sea surface is mainly manifested in the change of the sea surface height, the wave state acquisition subsystem includes a first processing module and a plurality of collectors 3 arranged in the target sea area 1, the collector 3 is used to collect the sea surface height data in the target sea area 1, and the first processing module is used to obtain all the sea surface height data and form the wave state data. More specifically, the target sea area 1 is first divided into a plurality of sub-areas 2, each sub-area 2 corresponds to at least one photovoltaic panel 41, and then a plurality of collectors 3 are deployed in each sub-area 2, the collector 3 collects the sea surface height data of a plurality of positions in the sub-area 2, and a reference plane can be generated based on the sea surface height data, and the angle of the reference plane is the angle after the photovoltaic panel 41 is affected by the sea surface waves in the sub-area 2 and changes its posture. The number and setting position of the collectors 3 can be determined according to the specific situation of the photovoltaic panel 41. For example, when each sub-area 2 corresponds to a photovoltaic panel 41, and the photovoltaic panel 41 is rectangular, a collector 3 is set at the four corner points of each sub-area 2, that is, four collectors 3 are set in each sub-area 2. On the other hand, two adjacent sub-areas 2 will have a common corner point, so the collectors 3 at the common corner point position can also be shared, and the sea surface height data collected by the four collectors 3 can determine a reference plane. It should also be noted that, because the sea surface height at the position of each collector 3 is difficult to predict with the occurrence of waves, this also leads to the fact that the sea surface height data collected by the four collectors 3 may not be able to directly determine a reference plane. At this time, the corner point where the sea surface height data of the collector 3 with the largest sea surface height data is located and the corner point where the sea surface height data of the collector 3 with the smallest sea surface height data is located can be determined as the reference corner point, and then the mean of the sea surface height data of the two collectors 3 is determined. Among the remaining two collectors 3, the one with the smallest difference between the sea surface height data and the mean is selected as the reference corner point, and the three reference corner points jointly determine the reference plane. In this way, no matter what the sea level data collected by the four acquisitions 3 are, a reference plane can be determined, and the similarity with the angle change of the photovoltaic panel 41 in the actual situation is higher. The first processing module can use an existing single chip microcomputer, which belongs to mature existing technology and is not repeated here.

[0043] like Figures 2 to 5As shown, the specific structure of the collector 3 includes a measuring rod 4 vertically arranged in the target sea area 1, and a plurality of through holes 5 evenly distributed in the vertical direction are opened on the measuring rod 4. A sensing component 6 is detachably arranged in the through hole 5. The sensing component 6 includes two electrode sheets 8 arranged at intervals. When seawater enters the through hole 5, the two electrode sheets 8 are connected to form a sensing path, and the first processing module can sense the current in the sensing path. When waves occur on the sea surface, seawater will enter the through hole 5 or flow out of the through hole 5. When seawater enters the through hole 5, because seawater has good conductivity, the two electrode sheets 8 of the sensing component 6 can be connected to form a sensing path. The first processing module senses the current in the sensing path, and can sense the state change of the sensing component 6. The height of the through hole 5 where the highest sensing component 6 is located is the sea level height data collected by the collector 3. One of the two electrode sheets 8 can be connected to a power supply device, and the other electrode sheet 8 is electrically connected to the data transmission interface of the first processing module. When the sensing path is formed, the first processing module is powered by the sensing path to achieve the sensing of the current in the sensing path.

[0044] In order to realize the sensing path, a wire slot 9 is fixedly provided on the measuring rod 4, and the two side walls of the wire slot 9 are fixedly connected to the measuring rod 4 through a connecting plate 15, and the fixed connection method can be welding. Two sensing cables 16 are passed through the wire slot 9, and the two sensing cables 16 are electrically connected to the two electrode sheets 8 respectively. Both ends of the wire slot 9 can be closed, so as to protect the sensing cables 16, prevent the sensing cables 16 from being damaged by seawater erosion, and extend the service life of the sensing cables 16.

[0045] Furthermore, the sensing component 6 includes a base 7 detachably arranged inside the through hole 5, the base 7 is in a step-like shape and the bottom is detachably connected to the inner wall of the through hole 5, and the two electrode sheets 8 are fixedly arranged on the top of the base 7. As the waves change, the seawater that originally entered the through hole 5 can also quickly flow out of the through hole 5 along the side wall of the base 7, avoiding being retained in the through hole 5 for a long time, causing the two electrode sheets 8 to always be in a conductive state, thereby causing errors in the sea level height data.

[0046] In order to facilitate the connection between the sensing cable 16 and the electrode sheet 8, two conductive wires 12 are passed through the base 7, one end of the conductive wire 12 is fixedly connected to the electrode sheet 8, and the other end of the conductive wire 12 is in contact with the conductive column 11 passed through the measuring rod 4. The conductive column 11 also extends into the wire groove 9. The sensing cable 16 can be connected to the conductive column 11 in the wire groove 9, and then connected to the electrode sheet 8 through the conductive column 11 and the conductive wire 12. In order to further facilitate the connection between the sensing cable 16 and the conductive column 11, a connecting piece 10 can be fixed on one end of the conductive column 11 located in the wire groove 9. The area of ​​the connecting piece 10 is larger than the cross-sectional area of ​​the conductive column 11. The sensing cable 16 can be connected to the connecting piece 10 by welding.

[0047] A positioning block 13 is fixedly arranged on the inner wall of the through hole 5, at least one elastic ring 14 is fixedly arranged on the peripheral side wall of the positioning block 13, a receiving groove for accommodating the positioning block 13 is provided on the base 7, and an annular groove for correspondingly accommodating the elastic ring 14 is provided on the inner wall of the receiving groove. Through the cooperation between the positioning block 13 and the receiving groove, the base 7 can be installed in the through hole 5 by plugging, which is simple and convenient, and the cooperation between the elastic ring 14 and the annular groove can improve the stability of the base 7 and prevent the base 7 from falling off.

[0048] like Figure 7 and 8 As shown, the regular wave simulation subsystem includes a photovoltaic bracket 27, the photovoltaic bracket 27 is rotatably connected to a substrate 40, a photovoltaic panel 41 is tiltedly arranged on the substrate 40, and the substrate 40 is also connected to a driving mechanism for driving the substrate 40 to rotate. After the regular wave simulation data is determined, the driving mechanism drives the substrate 40 to rotate, and the rotation of the substrate 40 drives the photovoltaic panel 41 to rotate, thereby adjusting the angle of the photovoltaic panel 41.

[0049] More specifically, two mounting blocks 38 are fixedly arranged on the photovoltaic bracket 27, a rotating shaft 39 is rotatably connected between the two mounting blocks 38, the substrate 40 is fixedly connected to the rotating shaft 39, and the driving mechanism includes a guide rod 35 movably arranged below the substrate 40, a sliding bearing 36 is sleeved on the guide rod 35, the sliding bearing 36 is fixedly connected to the rotating shaft 39 through a transmission rod 37, and the guide rod 35 is connected to a driver 33 for driving the guide rod 35 to move. When adjusting the angle of the photovoltaic panel 41, the driver 33 is first used to drive the guide rod 35 to move, and during the movement of the guide rod 35, the rotating shaft 39 is driven to rotate by the sliding bearing 36 and the transmission rod 37, and then the substrate 40 is driven to rotate by the rotating shaft 39, and finally the photovoltaic panel 41 is driven to rotate by the substrate 40, so as to adjust the angle of the photovoltaic panel 41. Because the sliding bearing 36 is slidably sleeved on the guide rod 35, the sliding bearing 36 can move up and down during the movement of the guide rod 35, thereby ensuring that it can be stably connected with the transmission rod 37.

[0050] Furthermore, the driving mechanism also includes two mutually parallel first rails 28, on which a support block 34 is slidably arranged, a second rail 29 is fixedly connected between the two support blocks 34, a slider 30 is slidably arranged on the second rail 29, a driver 33 is drivingly connected to a retractable connecting rod 32, and the retractable connecting rod 32 is rotatably connected to the slider 30 through a rotating connecting member 31, and a guide rod 35 is vertically arranged on the slider 30 or the support block 34. When the angle of the photovoltaic panel 41 needs to be adjusted, the driver 33 is used to drive the retractable connecting rod 32 to extend or shorten, and the retractable connecting rod 32 pulls the slider 30 to move during the deformation process, and the slider 30 then drives the second rail 29 and the support block 34 to move synchronously, and finally drives the guide rod 35 arranged on the support block 34 and the slider 30 to move, and finally drives the angle of the photovoltaic panel 41 to change through the guide rod 35. The specific process is as described above and will not be repeated here.

[0051] In order to further enhance the flexibility of the regular wave simulation subsystem and enable the regular wave simulation subsystem to control the photovoltaic panel 41 to change to more angles, the regular wave simulation subsystem also includes a rotating support platform, and the photovoltaic bracket 27 and the driving mechanism are both arranged on the rotating support platform. The rotating support platform specifically includes a base plate 20, and the base plate 20 is fixedly connected to the bearing platform 23 through a plurality of support rods 22. A rotating drive motor 21 is also fixedly arranged on the base plate 20, and the rotating drive motor 21 is driven and connected to a turntable 26, and the photovoltaic bracket 27 and the driving mechanism are both arranged on the turntable 26. The turntable 26 can be driven to rotate by the driving motor 21, thereby driving the photovoltaic bracket 27 and the driving mechanism to rotate synchronously, so that while adjusting the angle of the photovoltaic panel 41, the direction of the photovoltaic panel 41 can also be adjusted, and a more comprehensive simulation experiment can be performed on the posture changes of the photovoltaic panel 41 caused by the influence of the waves.

[0052] In order to limit the turntable 26 and prevent the vibration of the turntable 26 from adversely affecting the simulation experiment process, a plurality of fixed blocks 24 evenly distributed along the circumferential direction of the turntable 26 are fixed on the support platform 23, and positioning pins 25 are passed through the fixed blocks 24. An annular positioning groove is opened on the peripheral side wall of the turntable 26. The positioning pins 25 are inserted into the positioning groove to limit the turntable 26, thereby preventing the turntable 26 from vibrating.

[0053] like Figure 6As shown, the specific structure of the photovoltaic simulation subsystem is as follows: the photovoltaic simulation subsystem includes a plurality of latitudinal mounting rods 18 and a plurality of longitudinal mounting rods 17. The latitudinal mounting rods 18 and the longitudinal mounting rods 17 are staggered to form a plurality of intersections, and lighting fixtures 19 for providing light energy to the photovoltaic panel 41 are arranged at the intersections. The latitudinal mounting rods 18 and the longitudinal mounting rods 17 can be straight rods or curved rods. The lighting fixtures 19 are used to emit light to provide light energy. The lighting fixtures 19 at different positions can simulate the sun's irradiation of the photovoltaic panel 41 at different times. All lighting fixtures 19 can be controlled by a second processing module. The second processing module is similar to the first processing module and can be implemented by an existing single-chip microcomputer, which will not be described in detail here.

[0054] An offshore photovoltaic regular wave simulation experiment method is based on the above-mentioned offshore photovoltaic regular wave simulation experiment device, and the method includes the following steps.

[0055] S1. Select a target sea area 1, and divide the target sea area 1 into a plurality of sub-areas 2. After the target sea area 1 is selected, determine the solar movement rule based on the position of the target sea area 1. Specifically, because the movement of the sun has certain rules for a certain area, the position of the sun relative to the photovoltaic panel 41 will also change continuously during the movement of the sun, thereby affecting the power generation efficiency of the photovoltaic panel 41. In order to fully simulate the power generation of the photovoltaic panel 41 in the target sea area 1, the present invention needs to first determine the solar movement rule, and provide electrical energy to the photovoltaic panel 41 based on the solar movement rule during the subsequent simulation experiment.

[0056] S2. The wave state collection subsystem is used to collect the sea surface height data in the sub-area 2, and the wave state data is generated based on all the sea surface height data. Specifically, when the sub-area 2 is a rectangle, the sea surface height data of the four corner points of the sub-area 2 are collected, and then a reference plane is generated, and the direction and angle of the reference plane are the direction and angle of the photovoltaic panel 41 after being affected by the waves.

[0057] S3. Generate photovoltaic simulation data according to the wave state data using the experimental control subsystem, and control the regular wave simulation subsystem based on the photovoltaic simulation data to drive the photovoltaic panel 41 to move until the photovoltaic panel 41 reaches a state parallel to the reference plane.

[0058] S4. Use the photovoltaic simulation subsystem to provide light energy to the photovoltaic panel 41 during the operation of the photovoltaic panel 41. More specifically, the experimental control subsystem controls the photovoltaic simulation subsystem to provide light energy to the photovoltaic panel 41 based on the sun's movement rules, specifically, by adjusting the lighting fixture 19 to turn on or off to simulate different positions of the sun.

[0059] S5. Use the experimental control subsystem to collect and process the power generation data of the photovoltaic panel 41. By changing the angle of the photovoltaic panel 41 and the switch status of the lighting fixture 19, the power generation status of the photovoltaic panel 41 can be fully simulated. During the power generation process of the photovoltaic panel 41, the power generation power, power generation voltage, power generation current and other data of the photovoltaic panel 41 can be collected to form the power generation data of the photovoltaic panel 41. Finally, by analyzing the power generation data, it can be determined whether it is suitable to deploy the photovoltaic system in the current target sea area 1.
