Description

Technical Field

[0001] The present invention relates to the field of photovoltaic power generation, and specifically to a centralized management system and method for photovoltaic panels. Background Art

[0002] With the increasing annual environmental protection requirements in China, photovoltaic power generation, a clean energy source, has been vigorously developed. However, the bottleneck problems restricting the development of photovoltaic power generation have also become prominent:

[0003] 1. The photovoltaic panels are exposed to outdoor high and low temperature changes, damage from flying sand and stones, and human damage, etc., which exacerbate the aging and damage of the photovoltaic panels. The increase in the replacement and maintenance costs of the equipment means an increase in the power generation cost;

[0004] 2. Due to the easy aging and damage of the photovoltaic panels outdoors, it is necessary to monitor and defend the photovoltaic power plant, conduct drone inspections, and manual inspections and repairs, etc. The increase in the inspection cost also raises the power generation cost again;

[0005] 3. Due to the lighting problem, the photovoltaic panels need to be arranged dispersedly, which also results in overly dispersed transmission cables, increasing the probability of cable theft and the difficulty of cable damage repair and replacement, leading to an increase in the cost of photovoltaic power generation.

[0006] In summary, there is an urgent need for a centralized management system and method for photovoltaic panels, which can achieve local centralized management of photovoltaic panels, facilitate the inspection of photovoltaic panels; at the same time, improve the operating environment of photovoltaic panels, fundamentally solve the problem of easy damage and aging of photovoltaic panels, prevent the occurrence of events such as photovoltaic panel theft and cable theft, thereby reducing the power generation cost, and is of great significance to the popularization and development of photovoltaic power generation and the development of clean energy. Summary of the Invention

[0007] Aiming at the problems and deficiencies in the prior art, the purpose of the present invention is to provide a centralized management system and method for photovoltaic panels, which can achieve local centralized management of photovoltaic panels, facilitate the inspection of photovoltaic panels; at the same time, improve the operating environment of photovoltaic panels, fundamentally solve the problem of easy damage and aging of photovoltaic panels, prevent the occurrence of events such as photovoltaic panel theft and cable theft, thereby reducing the power generation cost and promoting the rapid development of photovoltaic power generation.

[0008] The technical solution of the present invention is as follows:

[0009] A centralized management system for photovoltaic panels includes a lighting module and a light scattering module, and the incident light obtained by the lighting module is transmitted to the light scattering module through an optical fiber.

[0010] The daylighting module includes a daylighting module body. A Fresnel lens is provided at the top of the daylighting module body, a connecting pipe is provided at the bottom, and a cavity communicating with the Fresnel lens and the connecting pipe is provided inside. One end of the connecting pipe extends into the cavity, and a daylighting concave lens is provided at the end. The other end extends to the outside of the daylighting module body and is connected to a transmission optical fiber. The cavity is filled with dry and clean air, and the focus is located on the central normal line of the Fresnel lens;

[0011] The light-diffusing module includes a light-diffusing module body. A photovoltaic panel is provided at one end, a light-diffusing component is provided at the other end, and a light-diffusing cavity is provided inside. The side of the photovoltaic panel facing the light-diffusing cavity is the light-receiving surface; the light-diffusing component includes a light-diffusing concave lens whose focus falls on the central normal line of the photovoltaic panel. The light-diffusing concave lens is connected to the bottom of the light-diffusing module body through an adjustment mechanism and is arranged at the light-emitting port of the transmission optical fiber. A light intensity sensor is provided on the photovoltaic panel. The adjustment mechanism can drive the light-diffusing concave lens to linearly reciprocate along the central normal line of the photovoltaic panel according to the detection result of the light intensity sensor to adjust the light-illuminated area of the photovoltaic panel irradiated through the light-diffusing concave lens.

[0012] The adjustment mechanism includes:

[0013] A fixed cylinder, connected to the bottom of the light-diffusing module body, with its axis coinciding with the central normal line of the photovoltaic panel. One end extends into the light-diffusing cavity, the other end is connected to the transmission optical fiber, and a thread is provided on the outer ring;

[0014] A rotating sleeve, whose inner ring is connected to the outer ring of the fixed cylinder through a thread pair. A light-diffusing concave lens is provided at the end facing the photovoltaic panel. The rotating sleeve can move along the axis of the fixed threaded cylinder under the drive of a drive component to adjust the distance between the light-diffusing concave lens and the photovoltaic panel;

[0015] The drive component includes a driving gear and a motor. The driving gear meshes with the outer ring of the rotating sleeve and drives the rotating sleeve to rotate. The motor is fixed on the light-diffusing module body on one side of the fixed cylinder and is connected to and drives the driving gear to rotate.

[0016] Through the setting of the adjustment mechanism, the distance between the light-diffusing concave lens and the light-receiving surface of the photovoltaic panel is adjustable. When the light is too dim, in order to ensure the light intensity, the light-illuminated area of the photovoltaic panel is reduced by adjusting the position of the light-diffusing concave lens; when the light is too strong, the light-illuminated area is increased by adjusting the position of the light-diffusing concave lens, and the excess light-illuminated area is irradiated on the light-diffusing module body to ensure that the photovoltaic panel will not be damaged by the too strong light.

[0017] An adjusting bracket is provided at the bottom of the daylighting module body for adjusting the light-receiving angle of the Fresnel lens.

[0018] A fault alarm indicator light is provided on the light-diffusing module body and is communicatively connected to a control system arranged in the power generation area. It is convenient to send an alarm message to the user when a fault occurs in the light-diffusing module, prompting the user to assign maintenance personnel for quick positioning and replacement.

[0019] The photovoltaic panel is detachably connected to the light-diffusing module body through a magnetic strip, facilitating the installation, disassembly, and replacement of the photovoltaic panel.

[0020] To reduce the area of the power generation region and improve space utilization, fixed feet are provided on the light-diffusing module body, and multiple light-diffusing modules in the light-emitting region can be stacked and connected vertically through the fixed feet.

[0021] The daylighting module body and the light-diffusing module body are pyramid-shaped, and the tapered end of the daylighting module body faces downward.

[0022] A method for centralized management of photovoltaic panels, characterized in that it is applied to the above-mentioned photovoltaic panel centralized management system, and includes the following steps:

[0023] Adjust the Fresnel lens angle of the daylighting module according to the sunlight conditions and the longitude and latitude of the installation location;

[0024] Obtain the light intensity measured by the light intensity sensor and compare it with the set value. If the light intensity is greater than the set value, adjust the rotating sleeve in the direction away from the photovoltaic panel until the light intensity is equal to the set value; if the light intensity is less than the set value, adjust the rotating sleeve in the direction closer to the photovoltaic panel until the light intensity is equal to the set value;

[0025] Calculate the light area received by the light-receiving surface of the photovoltaic panel based on the distance between the light-diffusing concave lens and the light-receiving surface of the photovoltaic panel, and divide the area of the Fresnel lens by the light area received by the light-receiving surface of the photovoltaic panel to obtain the daylighting coefficient k d , and calculate the power generation amount through the following formula

[0026]

[0027] In the formula, k d The daylighting coefficient, which is equal to the ratio of the daylighting area (the area of the Fresnel lens daylighting component area) to the light area received by the light-receiving surface of the photovoltaic panel (the scattered light area), T is the light transmittance of the daylighting module, α is the optical fiber transmission coefficient, l o is the laid optical fiber length, and the power generation amount of the traditional photovoltaic power generation system is W i .

[0028] To ensure the light transmission rate and minimize light loss, the laid optical fiber length in this application does not exceed 2 km.

[0029] The present invention separates daylighting from power generation. The daylighting part of the daylighting module is made of PMMA. Compared with photovoltaic panels, it has higher impact resistance, high and low temperature resistance, and wear resistance. In addition, its light transmittance can reach more than 94%, and the light transmittance can still reach about 91% under outdoor ultraviolet irradiation for 25 years; PMMA is cheap, has a low recycling value, is not easy to be stolen, and is suitable for large-scale laying in harsh outdoor environments. At the same time, since there are no electrical components, the failure rate of outdoor daylighting panels is extremely low, which greatly reduces the cost of inspection and maintenance; photovoltaic panels that are easy to damage, easy to age, and easy to replace and repair are placed in a clean room with constant temperature and humidity, which greatly increases the life of photovoltaic panels and the difficulty of management and maintenance. At the same time, due to the high cost of photovoltaic panels, they are often stolen and lost in remote outdoor areas. Placing them indoors fundamentally solves the problem of photovoltaic panel theft.

[0030] When the photovoltaic panels are aging or malfunctioning, the system will locate the photovoltaic panels with obvious voltage drops, and the indicator lights on the corresponding components will flash to prompt maintenance personnel to quickly locate and replace them. At the same time, since the indoor environment is clean and stable, and the photovoltaic panels are fixed with magnetic strips, maintenance personnel can disassemble and assemble the photovoltaic panels conveniently and quickly. Compared with traditional outdoor long-distance and bolt disassembly and assembly, the efficiency has been greatly improved.

[0031] In traditional photovoltaic power generation situations, photovoltaic panels may have shading problems due to various reasons. If one photovoltaic panel is blocked, it may affect the power generation efficiency of the entire photovoltaic panel group. Because the photovoltaic panel group is connected in series or parallel, the performance degradation of one photovoltaic panel will affect the current and voltage output of the entire photovoltaic panel group, and may even cause a hot spot effect, causing damage to the photovoltaic panel. In this application, the optical fiber is directed to the photovoltaic panel through the astigmatism concave lens in the closed astigmatism module, which can effectively avoid the above problems. In addition, by setting an adjustment mechanism to adjust the distance between the astigmatism concave lens and the photovoltaic panel, the area of ​​sunlight directed to the photovoltaic panel is adjusted to ensure that each photovoltaic panel can receive uniform and stable light, which further guarantees the power generation efficiency of the present invention.

Since there is an internal thread inside the rotating sleeve, it can move axially along the fixed threaded barrel during rotation, thereby driving the astigmatism concave lens embedded in the rotating sleeve to move back and forth and adjust the distance between it and the photovoltaic panel; the inner hole of the fixed barrel ensures the transmission of light; the magnetic strip is used for rapid replacement of photovoltaic panels.

[0060] Embodiment 2

[0061] A centralized management method for photovoltaic panels, having the above-mentioned centralized management system for photovoltaic panels, and the power management method includes the following steps:

[0062] A centralized management method for photovoltaic panels, characterized in that it is applied to the above-mentioned centralized management system for photovoltaic panels, and includes the following steps:

[0063] Adjust the Fresnel lens angle of the daylighting module according to the sunlight conditions and the longitude and latitude of the installation location;

[0064] Obtain the light intensity measured by the light intensity sensor and compare it with the set value. If the light intensity is greater than the set value, adjust the rotating sleeve in the direction away from the photovoltaic panel for the astigmatic concave lens until the light intensity is equal to the set value; if the light intensity is less than the set value, adjust the rotating sleeve in the direction close to the photovoltaic panel for the astigmatic concave lens until the light intensity is equal to the set value;

[0069] According to the existing general optical fiber technology, the optical fiber transmission coefficient α is generally -0.2 dB / km. It is recommended that the maximum laid length of the optical fiber in the present invention does not exceed 2 km, and the light transmittance T of the daylighting module is taken as 94%. According to the obtained daylighting coefficient k d Can take a value between 2 and 4. Although a too large daylighting coefficient can increase the light intensity, it will cause the surface temperature of the photovoltaic panel to be too high, which will instead reduce the power generation efficiency of the photovoltaic panel and will also have an impact on the service life of the photovoltaic panel. Finally, W j ≈1.71W i ~3.43W i , that is, the present invention can increase the power generation amount of photovoltaic panels of the same area by 1.71 to 3.43 times.
