Description

Technical Field

[0001] This application relates to the field of photovoltaic power generation technology, specifically to a photovoltaic tracking bracket device and control method. Background Technology

[0002] Solar photovoltaic (PV) power generation is one of the most important forms of solar energy utilization today. To improve the power generation and economic benefits of PV power plants, tracking solar PV systems can be used to enhance power generation efficiency. The power generation efficiency of PV modules is affected by the angle of direct sunlight. Tracking brackets ensure that PV modules receive the most sunlight within a certain rotation range, resulting in the highest power generation efficiency. In recent years, tracking brackets have been widely used to pursue maximum solar irradiance. Because tracking brackets contain rotating parts and are exposed to wind, sand, rain, and snow for many years, the stability and reliability of the entire PV power generation system are critical. Ensuring that PV modules minimize mutual interference effects, achieve optimal tilt and wind angles, and seek the best wind protection strategy, while ensuring the safety and stability of the PV bracket system under strong winds, and maximizing PV power generation efficiency, are the design goals of PV modules.

[0003] Currently, wind resistance strategies for single-axis / dual-axis photovoltaic tracking brackets primarily employ reinforced supports or active risk mitigation to enhance stability. Single-axis brackets, which track in only one direction and are known as solar tracking systems, offer high cost-effectiveness. Active risk mitigation involves the tracking system automatically leveling the modules during strong winds; this is a basic self-protection function. However, when the system's shape factor is large, damage begins at the weakest point. While this strategy provides some wind protection, it doesn't account for wind direction and speed, potentially leading to wind-induced resonance and excessive torque that could damage the modules and supports.

[0033] A photovoltaic (PV) power generation device includes a PV tracking bracket and PV modules. This application provides a highly stable and reliable adaptive single-axis anti-wind-induced resonance PV tracking bracket device and control method. While ensuring the tracking accuracy and power generation efficiency of the PV modules, it improves the PV device's ability to withstand wind loads. Considering the wind sensitivity of the modules, and combining knowledge from fluid dynamics and wind engineering, it ensures the flexible wind resistance of the modules.

[0034] Figure 1 This application illustrates a photovoltaic tracking bracket device according to an embodiment of the present application. The device includes:

[0035] Support column 9, bracket single shaft rotatably connected to the top of the support column 9, frame mounted on the bracket single shaft, turbulence flow device 3 rotatably connected to the frame, hydraulic rod 4 rotatably connected to the bottom of the frame and supported by the support column 9, and damping device 5;

[0036] The turbulence device 3 is connected to the driver 7 located on the support column 9; the hydraulic rod 4 is used to control the photovoltaic tracking angle, and the damping device 5 is used to control the wind resistance angle; a photovoltaic module is arranged inside the frame; a wind speed sensor 6 is arranged below the photovoltaic module, and the wind speed sensor 6 is used to measure the wind speed and wind direction of the airflow.

[0037] The driver 7 drives the bracket on a single axis according to wind speed and direction to control the angle of the photovoltaic module, and drives the hydraulic rod 4 to support the photovoltaic module to rotate.

[0038] In one possible implementation, the turbulence device 3 is installed at any position on the edge of the photovoltaic module on the frame; one turbulence device is installed on one set of photovoltaic modules.

[0039] In one possible implementation, the spoiler is a louvered spoiler.

[0040] In one possible implementation, the photovoltaic module includes a plurality of photovoltaic cells.

[0041] In one possible implementation, the device further includes a drive controller 8 mounted on the support column, the drive controller 8 being used to control the driver 7.

[0042] It should be noted that the "upwind" and "downwind" mentioned in this article refer to the relative upwind and relative downwind directions determined during installation based on the wind direction under most local climatic conditions.

[0043] The photovoltaic tracking bracket device disclosed in this application includes a photovoltaic module with a wind speed sensor. The photovoltaic module is mounted on a frame, and the wind speed sensors at both ends of the module can measure and calculate the wind speed and angle of the incoming wind. A louvered spoiler is installed under the frame in the windward direction and connected to a driver, which drives the module. The frame is supported by a single axis, which is controlled by the driver. This single axis simultaneously drives a hydraulic rod to support the rotation of the entire photovoltaic module. A damping device is located on the other side of the hydraulic rod. By adjusting the angle of the module and the spoiler, the vortex structure formed by wind-induced resonance can be destroyed, eliminating the resonance effect, improving aerodynamic performance, and stabilizing the photovoltaic device. At the same time, the drive controller and driver with built-in astronomical algorithms drive the single axis to control the angle of the module, achieving real-time tracking of sunlight and maximizing power generation efficiency.

[0044] Figure 2 This is a schematic diagram of a photovoltaic tracking bracket device provided in an embodiment of this application. It uses a wind speed sensor to measure wind speed and direction, uses a starting rod and a damping rod to improve the stability of the photovoltaic device, and uses a spoiler to destroy turbulent wake vortices, improve aerodynamic performance, and eliminate wind-induced resonance. Figure 3 , 1Figures 1, 2, and 4 show the front, side, and top views of the photovoltaic tracking bracket, respectively. 1-Single axis of the bracket, 2-Photovoltaic cell, 3-Break plate, 4-Hydraulic rod, 5-Damping rod, 6-Wind speed sensor, 7-Driver, 8-Drive controller, 9-Support column.

[0045] The bracket single axis 1 and photovoltaic cell 2 are surrounded by a frame; a spoiler 3 is installed downwind of the frame, which can weaken the airflow and reduce damping by utilizing the wake vortex effect; a hydraulic rod 4 is installed below the module to control the tracking angle, and a damping rod 5 is used on the other side to control the wind resistance safety angle; a wind speed sensor 6 is installed upwind of the module to measure the wind speed; the bracket single axis is driven by a driver 7 and automatically controlled by a drive controller 8; the photovoltaic module and frame are stabilized by a support column 9.

[0046] The entire system for controlling the angle of the photovoltaic panels includes: a system control box, a drive motor, a transmission mechanism, a coupling, a hydraulic rod, and a main shaft. The main shaft is controlled as follows: a coupling is installed in the middle of the main beam, symmetrically fitted with main shaft clamps. One end of the coupling connects to the system control box on the main body of the photovoltaic support, and the other end connects to the transmission mechanism. The transmission mechanism is connected to the drive motor, which in turn connects to the system control box. The system control box is mounted on the column connecting the main body of the photovoltaic support to the clamps. The hydraulic rod contains a built-in servo motor, which is connected to the system control box on the main body of the photovoltaic support. The system control box controls the hydraulic system via control signals, assisting the main shaft in adjusting its angle.

[0047] Based on the aforementioned disclosed photovoltaic tracking bracket device, its control method can realize four major functions: wind speed measurement, strong wind resistance mode, tracking-wind resistance composite control mode, and tracking mode. By comparing the wind speed measurement with the budget threshold calculated from wind tunnel experimental results, the system determines whether to activate the strong wind resistance mode, the tracking-wind resistance composite control mode, or the tracking mode. Its control strategy prioritizes the safety and stability of the photovoltaic system while also considering the photovoltaic bracket's tracking mode, ensuring maximum detection efficiency under the premise of photovoltaic system safety.

[0048] The following is an introduction Figure 5 The control method flow of the photovoltaic tracking bracket device is shown.

[0049] The first aspect is the wind speed measurement stage.

[0050] The vibration of photovoltaic (PV) supports and modules is determined by wind speed. When the PV modules begin to oscillate and generate an oscillation angle, a second threshold wind speed, v2, is defined. As the wind speed continues to increase, the vibration frequency generated by the lateral force of the wind becomes close to the natural frequency of the PV support, resulting in wind load resonance. At this point, the PV support experiences significant vibration, and a first threshold wind speed, v1, is defined. The PV system then activates its wind-resistant mode. Using the above method, preliminary wind tunnel tests calculate the safety angle model corresponding to each PV tracking support and set a first threshold wind speed v1 and a second threshold wind speed v2 (v1 > v2) for the environment. The vibration ranges from stability to the oscillation threshold v2, and from oscillation to the resonance threshold v1.

[0051] It is also necessary to calibrate the wind speed collected by the wind speed sensors in the photovoltaic array (wind speed sensors fixed on both sides below the frame of the upwind component); using wind tunnel experiments, under known wind speed and direction conditions at different fan speeds, wind speed sensors placed in the stable outlet section measure wind speed and direction data, compare them with the actual values, analyze the trend relationship between error curves, find abnormal data in the sensor readings, and calculate the standard wind speed value according to the linear regression equation to reset the wind speed sensor measurement benchmark.

[0052] The wind speed and direction v at the corresponding position of each photovoltaic tracking bracket are calculated using wind speed sensors.

[0053] The second aspect is the control phase of the photovoltaic tracking bracket.

[0054] First, the real-time wind speed v is obtained using a wind speed sensor, and it is determined whether it is greater than the first threshold v1.

[0055] When the real-time wind speed v exceeds the first threshold v1, the system activates the wind-resistant mode. This involves adjusting the hydraulic rod's rotation angle to α based on the wind speed v and a pre-set safety angle model, with a maximum rotation angle of 60°. α refers to the angle between the hydraulic rod and the support column. Simultaneously, the damping tie rod stabilization assembly is activated. Based on the wind direction calculated by the wind speed sensor, the spoiler is adjusted to the optimal angle θ (|θ|<30°), and further adjusted to Max(|α-θ|). θ refers to the angle between the spoiler blade spacing and the horizontal position (initial position).

[0056] If the real-time wind speed v is less than the first threshold v1, then it is further determined whether the real-time wind speed v is greater than the second threshold v2.

[0057] If the real-time wind speed v is greater than the second threshold v2, the photovoltaic wind-resistant tracking composite control mode is activated: the spoiler is adjusted to the optimal angle θ (|θ|<30°) according to the wind speed v and the pre-built safety angle model, and the hydraulic rod is adjusted to the optimal tracking angle according to the astronomical algorithm, with the adjustment angle being α' (|α'|<45°).

[0058] If the real-time wind speed v is less than the second threshold v2, the photovoltaic tracking mode is activated: the hydraulic rod is adjusted according to the optimal angle of the astronomical algorithm, and the adjustment angle is α' (|α'|<45°). At this time, the damping rod exhaust valve is engaged, and the damping rod is in a driven state.

[0059] The spoiler and damping rod are controlled separately by the system control box. The spoiler is rotated and opened to a certain angle by a rotating shaft, and then locked in place by a limit structure. The rotating shaft is controlled by a motor, which is controlled by the control box.

[0060] As can be seen, the photovoltaic tracking bracket provided in this application has a simple structure. It utilizes louvered spoilers to improve aerodynamic performance and eliminate wind-induced resonance. A dual protection mechanism of hydraulic push rods and damping rods prevents wind damage. The spoilers can be installed and fixed at any position on the edge of the photovoltaic modules in the photovoltaic array. The modular design allows for one set of spoilers per module, enabling installation and fixing at any position on the edge of the photovoltaic modules in the array. The control system includes three modes: wind-resistant mode, composite mode, and tracking mode, which can be flexibly switched according to environmental conditions. The primary goal is to ensure the stability of the photovoltaic power generation system, while the tracking mode maximizes the system's power generation efficiency.

[0061] In summary, this application provides a photovoltaic tracking bracket device, comprising: a support column, a bracket single shaft rotatably connected to the top of the support column, a frame mounted on the bracket single shaft, a turbulence-disrupting device rotatably connected to the frame, and a hydraulic rod and a damping device rotatably connected below the frame and supported by the support column; the turbulence-disrupting device is connected to a driver located on the support column; the hydraulic rod is used to control the photovoltaic tracking angle, and the damping device is used to control the wind resistance angle; a photovoltaic module is disposed within the frame; a wind speed sensor is disposed below the photovoltaic module, and the wind speed sensor is used to measure the wind speed and direction; the driver drives the bracket single shaft according to the wind speed and direction to control the angle of the photovoltaic module, and drives the hydraulic rod to support the rotation of the photovoltaic module. This device improves the photovoltaic device's ability to withstand wind loads while ensuring the tracking accuracy and power generation efficiency of the photovoltaic module.

[0062] Based on the same technical concept, embodiments of this application also provide a control method for a photovoltaic tracking bracket device, such as... Figure 6 As shown, the method includes:

[0064] Step 602: Determine whether the real-time wind speed is greater than the resonant wind speed threshold;

[0065] Step 603: If the real-time wind speed is greater than the resonant wind speed threshold, then adjust the rotation angle of the hydraulic rod to be in the first rotation angle range and adjust the rotation angle of the turbulence device to be in the target angle range according to the real-time wind speed and the preset safety angle model.

[0066] Step 604: If the real-time wind speed is less than or equal to the resonant wind speed threshold, then determine whether the real-time wind speed is greater than the oscillating wind speed threshold.

[0067] Step 605: If the real-time wind speed is greater than the swing wind speed threshold, then adjust the rotation angle of the hydraulic rod to be in the second rotation angle range and adjust the rotation angle of the turbulence device to be in the target angle range according to the real-time wind speed and the preset safety angle model.

[0068] Step 606: If the real-time wind speed is less than or equal to the swing wind speed threshold, then adjust the hydraulic rod to be in the second rotation angle range.

[0069] Wherein, the rotation angle of the hydraulic rod is the angle between the hydraulic rod and the support column, and the rotation angle of the turbulence device is the angle between the blade distance and the horizontal position of the turbulence device.
