Description

TECHNICAL FIELD

[0002] With the shortage of world energy, solar energy is widely developed and utilized. In the field of comprehensive development and application of solar energy, accurate measurement and construction of a solar radiation combination model is the key to improving the utilization efficiency of solar energy. In the process of measuring solar radiation, the component of the slope solar total radiation includes direct solar radiation, sky scattered radiation and ground reflected radiation, and the numerical value of each measurement component has significant differences in the random combination of different geographical locations, orientations and inclination angles.

[0028] The present application provides a component measuring device for optimizing a solar radiation combination model, as shown in Figure 1 The component measuring device for optimizing a solar radiation combination model of the present embodiment can generally include a vertical pole 100, two groups of solar radiation component measuring arms 110, and solar radiation component sensors 120. The vertical pole 100 is configured to be arranged along a longitudinal direction and rotatable about its center. The two groups of solar radiation component measuring arms 110 are respectively arranged to extend laterally from the vertical pole 100 and are configured to be rotatable about an axis along the extending direction relative to the vertical pole 100. The extending directions of the two groups of solar radiation component measuring arms 110 are arranged orthogonally in projection on a preset projection plane, as shown in Figure 2As shown, the projection plane is perpendicular to the vertical rod 100, that is, the installation plane of the component measuring device. Each set of solar radiation component measuring arms 110 is respectively arranged with solar radiation component sensors 120 facing opposite directions at the extended end. The vertical rod 100 can rotate along its center, so that the entire measuring device can rotate 360° horizontally, that is, the two sets of solar radiation component measuring arms 110 can rotate a full circle, and the solar radiation component sensors 120 arranged on the component measuring arms can cover each direction. The two sets of measuring arms are extended in a perpendicular projection manner and can rotate around the axis of the extension direction, cooperating with the rotation of the vertical rod 100, to realize measurement at any inclination angle from horizontal to vertical. This all-around and multi-angle measurement method overcomes the limitation of traditional measuring devices that can only measure a part of fixed directions and inclination angles, and truly realizes full-direction and full-inclination solar radiation component measurement, obtains comprehensive data, and can meet the measurement needs of different geographical locations and equipment installation angles.

[0029] Each set of measuring arms is arranged with solar radiation component sensors 120 facing opposite directions at the end, and by comparing the data collected by the two-direction solar radiation component sensors 120, the influence of environmental interference factors on the measurement results can be effectively offset. For example, in the case of local shading or uneven ambient light, the data of the two opposite-direction solar radiation component sensors 120 can be verified and calibrated with each other, thereby reducing measurement error and ensuring that the collected data of solar direct radiation, sky scattered radiation, and ground reflected radiation is more accurate and reliable.

[0030] The component measuring device also includes two sets of steering rudders 130. As shown, Figure 3 Both sets of steering rudders 130 are arranged on the vertical rod 100, and each set of steering rudders 130 is used to connect the vertical rod 100 and a set of solar radiation component measuring arms 110 and can drive the set of solar radiation component measuring arms 110 to rotate relative to the vertical rod 100. The steering rudders 130 have high-precision angle control capability and can accurately drive the solar radiation component measuring arms 110 to rotate to a specified angle according to a preset program or external instructions. Compared with manual adjustment, the rudder control can control the angle error in a very small range (such as ±0.1°), ensuring that the measuring arms are always in the ideal measurement position during full-direction and full-inclination measurement, avoiding angle deviation caused by human operation, and thereby improving the accuracy and reliability of the measurement data.

[0031] The steering servo 130 should control the solar radiation component measuring arm 110 to hover for a period longer than the response time of the solar radiation component sensor 120. To ensure measurement stability, the response time should be maintained at 30 seconds or more. The solar radiation component sensor 120 needs sufficient time to accurately respond to solar radiation in the environment and stabilize its output data. If the hovering time of the measuring arm is too short, the solar radiation component sensor 120 may not have reached a stable state, and the data acquired at this time will not accurately reflect the solar radiation situation at that location, resulting in a large error. However, when the hovering time is longer than the response time of the solar radiation component sensor 120, the solar radiation component sensor 120 has enough time to stabilize and output accurate and reliable measurement data, thereby improving the accuracy of the measurement of each component of solar radiation.

[0032] Each set of solar radiation component measuring arms 110 may include a radially extending rod 111 and a tangentially mounted rod 112. For example... Figure 3 and Figure 4 As shown, the first end 114 of the radial extension rod 111 is connected to the corresponding steering servo 130. The second end 115 of the radial extension rod 111 is connected to the middle of the tangential mounting rod 112. The radial extension rod 111 and the tangential mounting rod 112 are arranged perpendicularly, with solar radiation component sensors 120 facing opposite directions mounted at both ends of the tangential mounting rod 112. This arrangement allows the two solar radiation component sensors 120 to be located in different spatial positions as much as possible, reducing the influence of local environmental differences (such as airflow, partial obstruction, etc.) on the measurement results. Simultaneously, the perpendicular arrangement allows the solar radiation component sensors 120 to more sensitively sense solar radiation in different directions. By comparing the data from the two solar radiation component sensors 120, the actual solar radiation situation can be calculated more accurately, effectively improving the accuracy and reliability of the measurement.

[0033] It should be noted that the "first end 114" and "second end 115" of the radial extension rod 111 should be understood as follows: the end closer to the servo (upright rod 100) is the first end 114, and the end farther away from the servo (upright rod 100) is the second end 115. Alternatively, it can be understood as the end of the radial extension rod 111 that connects to the tangential mounting rod 112 is the second end 115.

[0034] Each set of solar radiation component measuring arm 110 can also include an angle adjustment block 113. The angle adjustment block 113 is arranged at both ends of the tangential mounting rod 112 and can rotate relative to the two ends of the tangential mounting rod 112. It is used to adjust the detection angle of the solar radiation component sensor 120. By arranging the angle adjustment block 113, the operator can fine-tune the detection angle of the solar radiation component sensor 120 according to the actual measurement requirements. For example, in different application scenarios, researchers can flexibly adjust the detection angle of the solar radiation component sensor 120 according to specific research needs, such as studying the distribution characteristics of solar radiation on surfaces with different inclination angles, or simulating the receiving angle of a specific type of solar energy equipment, to obtain more targeted measurement data and provide stronger support for related research and application.

[0035] Each set of steering engine can also include a servo motor 131 and a reducer 132. As shown in Figure 5 The servo motor 131 is used to provide torque for the rotation of the solar radiation component measuring arm 110. The reducer 132 is used to reduce the rotation speed of the steering engine output and amplify the torque of the steering engine output. The servo motor 131 has good control accuracy and response speed, and can accurately control the rotation angle and position of the solar radiation component measuring arm 110. This is crucial for accurately measuring solar radiation components in different directions and angles, and can ensure that the measuring arm rotates according to the preset angle, improving the accuracy and reliability of the measurement. The function of the reducer 132 is to reduce the rotation speed of the steering engine output and amplify the output torque. Through the reducer 132, the high rotation speed of the servo motor 131 can be reduced to a speed suitable for the rotation of the measuring arm, and the torque can be amplified, so that the measuring arm can rotate more powerfully. This helps to improve the rotation stability and control accuracy of the measuring arm, especially when the angle of the measuring arm needs to be accurately adjusted, achieving more accurate rotation control.

[0036] The solar radiation component sensor 120 can be a shadow mask type solar radiation component sensor 120. This type of solar radiation component sensor 120 can effectively block the direct sunlight through the shadow mask, avoiding the interference of direct light on the measurement results, so that the scattered radiation component in the solar radiation can be more accurately measured. In calculating the total solar radiation, by accurately measuring the direct radiation and scattered radiation respectively and then adding them together, a more accurate result can be obtained.

[0037] In some optional embodiments, the component measuring device also includes a bottom box 200. As Figure 1As shown, the bottom box 200 is connected with the bottom of the vertical pole 100 through the turntable mechanism 300, and the bottom box 200 is used to support the vertical pole 100 and drive the vertical pole 100 to rotate along the center thereof. By driving the vertical pole 100 to rotate along the center thereof through the turntable mechanism 300, the solar radiation component measuring arm 110 can be flexibly adjusted in the horizontal direction. In this way, no matter how the position of the sun in the sky changes, the solar radiation component measuring arm 110 can be adjusted to the optimal angle to more accurately measure the solar radiation component in different directions.

[0038] The turntable mechanism 300 can include a turntable 310 and a turntable mounting bearing seat integrated device 320. As shown, Figure 6 The turntable 310 is connected with the bottom of the vertical pole 100 and is used to drive the vertical pole 100 to rotate. The turntable mounting bearing seat integrated device 320 is fixedly connected with the upper side of the upper surface mounting plate 210 of the bottom box 200, and the turntable 310 is connected with the inner ring of the bearing in the turntable mounting bearing seat integrated device 320. When the component measuring device is in operation, the mounting bearing seat of the turntable mounting bearing seat integrated device 320 is fixedly connected with the upper surface of the box, the turntable 310 is connected with the inner ring of the bearing in the turntable mounting bearing seat integrated device 320, and the turntable 310 and the turntable mounting bearing seat integrated device 320 can rotate relative to each other. The turntable mounting bearing seat integrated device 320 can provide a rotating environment for the turntable 310 and provide support for the turntable 310. The high-precision fit of the bearing can reduce the resistance and shaking during rotation, so that the rotation of the turntable 310 and the vertical pole 100 is more stable and smooth, ensuring the accuracy and reliability of the solar radiation component measuring arm 110 when adjusting the angle, which helps to improve the measurement accuracy.

[0039] In the component measuring device, the turntable 310 can drive the vertical pole 100 to rotate, the steering engine 130 can drive the solar radiation component measuring arm 110 to rotate, and the angle adjusting block 113 can drive the solar radiation component sensor 120 to rotate. The design that the turntable 310, the steering engine 130 and the angle adjusting block 113 respectively drive different components to rotate can realize the measurement of the solar radiation component in all directions and all inclination angles.

[0040] The turntable mechanism 300 can further include a rotating shaft 330, a rotating disc driving motor 340, and a synchronous pulley assembly 350. The rotating shaft 330 is arranged on the lower side of the upper surface mounting plate 210 and fixedly connected with the rotating disc 310, for outputting power to the rotating disc 310. The rotating disc driving motor 340 is used to drive the rotating disc 310 to rotate. The synchronous pulley assembly 350 is arranged between the rotating disc driving motor 340 and the rotating shaft 330, for transmitting the torque output by the rotating disc driving motor 340 to the rotating shaft 330. The synchronous pulley assembly 350 can efficiently transmit the torque output by the rotating disc driving motor 340 to the rotating shaft 330, thereby driving the rotating disc 310 to rotate. The synchronous pulley has the characteristics of high transmission efficiency and small energy loss through the transmission of the pulley, and can ensure that the power of the rotating disc driving motor 340 is effectively converted into the rotating power of the rotating disc 310, reduce the loss in the power transmission process, and improve the energy utilization efficiency of the turntable mechanism 300.

[0041] The person skilled in the art can set the size of the pulley in the synchronous pulley assembly 350 according to actual needs to achieve different transmission efficiencies. A suitable transmission mode, such as flat belt transmission or synchronous belt transmission, can also be selected.

[0042] The turntable mechanism 300 can further be provided with a turntable speed reducer 360, which is used to reduce the rotating speed of the rotating disc driving motor 340 and amplify the torque of the rotating disc driving motor 340. The turntable mechanism 300 usually needs precise speed control to meet different measurement or experimental requirements. The rotating disc driving motor 340 generally has a high rated rotating speed, but in actual application, the turntable can not need such a high rotating speed. The turntable speed reducer 360 can reduce the high rotating speed of the motor to a suitable range, so that the turntable can rotate at a slower and more stable speed, thereby realizing precise angle positioning and control. For example, when measuring the solar radiation component, the turntable needs to rotate slowly at a specific speed, so that the solar radiation component measuring arm 110 can accurately stop at different positions for data collection, and the turntable speed reducer 360 can well meet this demand.

[0043] The bottom box body 200 can further include a model dynamic optimization engine device 220, such as Figure 1 and Figure 7As shown, the model dynamic optimization engine device 220 can automatically control the two groups of solar radiation component measurement arms 110 to hover at any position in real time according to the cloud-end issued control instructions. The model dynamic optimization engine device 220 can also be used to process and analyze the data measured by each solar radiation component sensor 120. It can automatically remove noise, correct bias, and smooth the data, etc., so as to improve the quality and reliability of the data. For example, in a complex environment, the solar radiation component sensor 120 may be subject to various disturbances, causing fluctuations in the measured data. Through the data processing function of the model dynamic optimization engine device 220, these interference factors can be effectively eliminated, so that the measured data can more truly reflect the actual situation of the solar radiation component.

[0044] The model dynamic optimization engine device 220 can be built-in with an adaptive algorithm, which can derive a full-azimuth and full-inclination solar radiation optimal combination model at multiple time precisions of hourly, daily, monthly, and yearly, and achieve fitting regression results of the solar radiation optimal combination model parameters based on historical data.

[0045] The bottom box 200 can also be provided with a mounting structure 370 for fixing the component measurement device in the use environment. The mounting structure 370 can be a foundation bolt mounting structure 370 or a welded fixing structure, etc. Those skilled in the art can use mounting structures 370 with the same or similar functions to fix the component measurement device in the use environment under the technical idea of the above mounting structure 370.

[0046] The bottom box 200 can also be provided with a box door 230 for opening and closing the box. The box door 230 can facilitate technicians to check, debug and maintain the devices inside the box, such as the turntable mechanism 300, the model dynamic optimization engine device 220, and the driving equipment (servo motor 131) of the solar radiation component measurement arm 110. When the equipment fails, the box door 230 can be quickly opened to replace or repair the faulty parts, reduce the equipment downtime, and improve the maintainability of the equipment.

[0047] The embodiment also provides a control method for optimizing a solar radiation combination model component measurement device, which is used to control the component measurement device of any of the above embodiments, such as Figure 8 As shown, the control method at least includes the following steps S801 to S805.

[0048] Step S801, obtaining measurement data of each solar radiation component sensor at different hovering positions.

[0049] Step S802, input the measurement data into the solar radiation model combination respectively to obtain the direct solar radiation, horizontal plane scattering radiation value, ground reflection radiation and inclined plane sky scattering radiation.

[0050] Step S803, determine whether the component measurement device fails according to the direct solar radiation.

[0051] Step S804, in the case where the component measurement device does not fail, select the corresponding solar radiation model combination according to the historical data.

[0052] Step S805, optimize the structure of the horizontal plane direct scattering separation empirical model, the ground albedo empirical model and the inclined plane sky scattering radiation model according to the horizontal plane scattering radiation value, the ground reflection radiation and the inclined plane sky scattering radiation respectively.

[0053] The measurement data of each solar radiation component sensor at different hovering positions are input into multiple models, such as the inclined plane direct solar radiation theoretical model, the horizontal plane direct scattering separation empirical model, the ground albedo empirical model and the inclined plane sky scattering radiation model, to obtain multiple key parameters such as the direct solar radiation, the horizontal plane scattering radiation value, the ground reflection radiation and the inclined plane sky scattering radiation. This multi-model fusion method can comprehensively cover each component of solar radiation and describe the characteristics of solar radiation from different angles and aspects, providing rich and comprehensive data basis for subsequent analysis and research. Different models model different aspects of solar radiation, and the combination of theoretical models and empirical models can fully utilize their respective advantages. The theoretical model is based on physical principles and mathematical derivation, and has high accuracy and universality; the empirical model is established based on a large amount of actual observation data, and can better reflect the complex factors in the actual situation. By inputting the data of the solar radiation component sensor into these models for calculation, the data can be calibrated and optimized to improve the accuracy and reliability of the data.

[0054] The direct solar radiation and the oblique sky scattering radiation can be used as the verification values of the horizontal plane direct-scattered separation empirical model to verify the accuracy of the horizontal plane direct-scattered separation empirical model. In addition, the direct solar radiation and the oblique sky scattering radiation are input values of the oblique plane direct solar radiation theoretical model and the oblique sky scattering radiation model. The ground reflected radiation can be used as the verification value of the ground albedo empirical model to verify the accuracy of the ground albedo empirical model. By comparing the independently calculated direct solar radiation and oblique sky scattering radiation with the calculation results of the horizontal plane direct-scattered separation empirical model, the accuracy of the empirical model can be directly verified. If the deviation between the calculation results of the model and the verification values is found, the model can be adjusted and optimized to more accurately reflect the actual solar radiation. Similarly, the ground reflected radiation as the verification value of the ground albedo empirical model can also help to find the shortcomings of the model, so as to improve the model and improve the calculation accuracy of the ground albedo.

[0055] The expression form of the optimal model of the horizontal plane direct-scattered separation empirical model is different under different conditions such as geographical location and weather conditions. For example, the expression of the horizontal plane direct-scattered separation empirical model can be: wherein, represents the diffuse-to-global ratio, which is the ratio of the horizontal plane sky scattering radiation to the horizontal plane total radiation. represents the clearness index, which is the ratio of the horizontal plane total radiation to the horizontal plane extraterrestrial radiation, which can be calculated by theory. Under the condition of knowing the horizontal plane total radiation, the horizontal plane sky scattering radiation and the horizontal plane direct radiation can be calculated by different function expressions.

[0056] The oblique plane direct solar radiation theoretical model can be: wherein, represents the oblique plane received direct solar radiation, represents the horizontal plane received direct solar radiation, which is calculated by the horizontal plane direct-scattered separation model, and the unit is W / m2. is the solar zenith angle, which is the complementary angle of the solar altitude angle, representing the angle of incidence of the solar light on the horizontal plane, is the angle of incidence of the sun on the inclined plane, and the unit is °.

[0057] The ground albedo empirical model can be: wherein, represents the oblique plane received ground reflected radiation, and the unit is W / m2. is the inclination, and the unit is °. represents the albedo, which is the ratio of the ground reflected radiation to the horizontal plane total radiation, and is different according to different ground values. represents the horizontal total radiation, and the unit is W / m2. The oblique sky scattering radiation model can be:​

[0058] wherein, represents the sky scattered radiation of the inclined plane, represents the sky scattered radiation of the horizontal plane, and the units are W / m2.

[0059] The above-mentioned horizontal plane direct scattered separation empirical model, the ground albedo empirical model and the inclined plane sky scattered radiation model are all components of the optimization combination model. Through continuous optimization, the horizontal plane direct scattered separation empirical model, the ground albedo empirical model and the inclined plane sky scattered radiation model are continuously optimized to meet the needs of researchers for measurement accuracy.

[0060] The optimization process of the horizontal plane direct scattered separation empirical model can be: when the two groups of solar radiation component measuring arms are rotated to the position that the long side is perpendicular to the horizontal plane, at this time, the two solar radiation component sensors on the upper side observe the horizontal plane total radiation and the horizontal plane sky scattered radiation, if the observation data of the solar radiation component sensors are consistent, it means that the measurement error of the component measuring device on the horizontal plane is consistent, at this time, different horizontal plane direct scattered separation empirical models are used to calculate the horizontal plane scattered radiation value respectively, and compared with the measurement results to select the optimal model. The optimal model may change with the geographical location of the device, the length of the measurement data used.

[0061] The optimization process of the ground albedo empirical model can be: when the two groups of solar radiation component measuring arms are rotated to the position that the long side is perpendicular to the horizontal plane, the difference between the solar total radiation measurement values of the solar radiation component sensors on the upper and lower sides of one group of solar radiation component measuring arms can obtain the ground reflected radiation, and then the albedo of the ground can be calculated, at this time, it can be compared with the value of the albedo of the ground given in the existing parameter table, and it can also be compared with the calculated value of the existing ground albedo empirical model to select the optimal ground albedo empirical model under the ground.

[0062] The optimization process of the inclined plane sky scattered radiation model can be: the scattered radiation values observed and recorded by the solar radiation component sensors at different inclined plane positions minus the ground reflected radiation calculated by the above-mentioned method are the inclined plane sky scattered radiation values, which are indirect measurement values. The calculated values of different forms of inclined plane sky scattered radiation model are compared with the indirect measurement values of the solar radiation component sensors at different positions to select the optimal model. The optimal model may change with the geographical location of the device, the length of the measurement data used, the orientation and the range of inclination.
