[0027] The technical scheme of the utility model will be described clearly and completely in combination with the drawings, obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0028] In addition, the technical features involved in different embodiments of the utility model described below can be combined with each other as long as there is no conflict.

[0029] The photovoltaic support is usually constructed in unattended area such as mountain, and the environment is bad, and it is difficult to monitor, so the photovoltaic module cannot be monitored comprehensively and accurately, and cannot provide timely and effective data support for power station operation state evaluation and real-time control of power station.

[0030] The embodiment of the utility model provides a kind of monitoring device of mountain photovoltaic flexible support, as shown in Figure 1 As shown, it includes: transmitter 10, environmental monitoring appearance 20, inverter sampling device 30 and box-type transformer 40, wherein:

[0031] The transmitter 10 is used for real-time monitoring of the inclination and azimuth angle of the mountain photovoltaic module. In the mountain photovoltaic environment, the installation angle of the photovoltaic module is easily affected by factors such as terrain undulation and foundation settlement. By accurately monitoring the inclination and azimuth angle of the module through the transmitter, small changes in the angle of the module can be found in time, and accurate data for evaluating the power generation potential of the photovoltaic area is provided.

[0032] The environmental monitor 20 is used for real-time monitoring of the actual light radiation received by the mountain photovoltaic area; the environmental monitor can monitor the actual light radiation received by the photovoltaic area in real time. The illumination conditions in the mountain area are disturbed by various factors such as mountain orientation, vegetation coverage, and weather changes. The monitor can accurately measure the light radiation in different areas and at different times, and provide accurate data for evaluating the power generation potential of the photovoltaic area.

[0033] The inverter data acquisition device 30 is connected with the transmitter 10 and the environmental monitor 20, and is used for transmitting the data collected by the transmitter 10 and the environmental monitor 20 through the optical fiber channel, converting the voltage through the box-type transformer 40, and sending the data to the monitoring platform of the booster station.

[0034] In the embodiment, the inverter data acquisition device transmits the data collected by the transmitter and the environmental monitor through the optical fiber channel. The optical fiber channel utilizes the existing channel of the inverter and the box-type transformer, and this cooperative working mode reduces the cost and complexity of separately laying a data transmission line, and improves the economy and reliability of the entire system. The optical fiber has the characteristics of strong anti-electromagnetic interference capability, and in the mountain environment, there may be various interference sources such as electrical equipment and lightning activities around, and the optical fiber can effectively avoid these interferences, ensuring the stability and accuracy of data transmission. Moreover, the optical fiber has a large bandwidth, and can meet the high-speed transmission requirements of a large amount of data, and there is no situation of data congestion or loss, ensuring that the monitoring platform can timely and completely receive the monitoring data. The data is sent to the monitoring platform of the booster station after voltage conversion by the box-type transformer, so that the data transmission and power transmission can be organically combined. In the mountain photovoltaic system, the distance from the photovoltaic area to the booster station may be far, and the box-type transformer converts the voltage to realize efficient transmission of electrical energy, and also provides convenience for data transmission.

[0035] The monitoring device of the mountain photovoltaic flexible support provided by the embodiment of the utility model, transmitter and environmental monitor are responsible for data acquisition, inverter data acquisition device is as the core hinge of data transmission, the box-type transformer assists data transmission while realizing voltage conversion, and various equipment is closely coordinated, and forms a complete monitoring system. For example, the inverter data acquisition device can receive data from the transmitter and the environmental monitor at the same time, and uniformly processes and transmits the data, avoiding the problems of scattered data and incompatibility, improving the overall operation efficiency of the system, and finally all the collected data is sent to the monitoring platform of the booster station in a unified way, such asFigure 2 The monitoring interface example is shown. Such design facilitates the comprehensive management of the mountain photovoltaic flexible support system by the monitoring platform. The operation and maintenance personnel can simultaneously view the angle data, light radiation data and other related electrical data of the photovoltaic module on the monitoring platform, realize real-time and centralized monitoring of the entire mountain photovoltaic system, facilitate timely discovery of problems and taking of corresponding measures, and at the same time, the component inclination angle, azimuth angle and light radiation measured by the device correct the light power prediction model and are supplemented to the database, so that the subsequent light power prediction is more accurate.

[0036] Due to the real-time and accurate collection and transmission of data, the monitoring platform can perform real-time analysis based on the data. When the inclination angle or azimuth angle of the photovoltaic module exceeds the normal range or the light radiation appears abnormal fluctuation, the system can timely send a warning signal. For example, when the photovoltaic module angle changes due to strong wind weather or the light radiation sharply decreases due to heavy rain weather, the operation and maintenance personnel can be notified in the first time, so as to quickly go to the scene for inspection and repair, reducing the power generation loss caused by equipment failure or environmental factors. The long-term accumulated monitoring data can provide strong support for operation and maintenance decision. By analyzing the influence of component angle change and light radiation change under different seasons and different weather conditions on power generation, the operation and maintenance personnel can formulate more scientific and reasonable operation and maintenance strategies. For example, according to the data to determine the best component cleaning cycle, or adjust the fixing mode of the component to adapt to the long-term stability requirement under the complex mountain terrain.

[0037] Further, as shown in Figure 3 The transmitter 10 in the embodiment includes a first microcontroller 101, a first collector 102 and a first RS485 interface 103. The input end of the first microcontroller 101 is connected with the output end of the first collector 102, the output end of the first microcontroller 101 is connected with the input end of the first RS485 interface 103, and the output end of the first RS485 interface 103 is connected with the inverter sampling device 30. The first microcontroller 101 acquires the inclination angle and azimuth angle data of the photovoltaic module collected by the first collector 102 and outputs to the inverter sampling device 30 through the first RS485 interface.

[0038] The first collector 102 in the embodiment includes an inertial measurement unit for collecting the inclination and azimuth angle data of the mountain photovoltaic module. The inertial measurement unit generally includes an accelerometer, a gyroscope and a magnetometer. The accelerometer is used to measure acceleration, and through integration operation, velocity and displacement information can be obtained; the gyroscope is used to measure angular velocity, and through integration, angular change can be obtained; the magnetometer is used to measure the magnetic field intensity, and is used to determine the azimuth angle. When collecting the inclination and azimuth angle data of the mountain photovoltaic module, the accelerometer can measure the inclination of the photovoltaic module relative to the direction of gravity, the gyroscope can assist in measuring the dynamic change of the angle, and the magnetometer can determine the azimuth angle of the module. The data of the three sensors are processed through a fusion algorithm (such as a mature existing algorithm such as Kalman filtering), to obtain more accurate inclination and azimuth angle information. In other embodiments, a two-axis inclination sensor can be used to measure the angle based on the principle of gravity or acceleration. Due to the complex mountain terrain, the installation surface of the photovoltaic module is often not horizontal, and the two-axis inclination sensor can be used to monitor and adjust the inclination of the photovoltaic module in real time, so that the photovoltaic module reaches the best light collecting angle; the electronic compass can be used to collect the azimuth angle, which measures the azimuth angle by using the earth's magnetic field, has a magnetic sensor inside, can detect the component direction of the earth's magnetic field on the horizontal plane, and is not limited to this as an example.

[0039] The environmental monitor 20 includes a second microcontroller 201, a second collector 202 and a second RS485 interface 203. The input end of the second microcontroller 201 is connected with the output end of the second collector 202, the output end of the second microcontroller 201 is connected with the input end of the second RS485 interface 203, and the output end of the second RS485 interface 203 is connected with the inverter sampling device 30. The second microcontroller 201 acquires the light radiation amount actually received by the photovoltaic area collected by the second collector 202, and outputs the light radiation amount to the inverter sampling device through the second RS485 interface.

[0040] Further, the second collector in the utility model embodiment comprises: total radiation table, direct radiation table, scattering radiation table, split light radiation table. The total radiation table is mainly used for measuring total solar radiation, including direct solar radiation and sky scattering radiation, and is usually composed of sensing components (thermoelectric pile), glass cover and accessories, etc., has wide measuring range and high precision; by long-term monitoring of the change of total solar radiation, in combination with the performance parameters of photovoltaic cell panel, the power generation of power station can be predicted, and the maintenance and repair time of power station can be reasonably arranged; the direct radiation table is mainly used for measuring direct solar radiation, and can accurately distinguish direct solar radiation and scattering radiation; the scattering radiation table can accurately measure the intensity of sky scattering radiation, and is very helpful for studying atmospheric optical characteristics and the performance of photovoltaic power generation under different sky conditions; through the combined data of the three tables, the proportion of direct radiation and scattering radiation in solar radiation at a specific location and time can be known in detail. For example, the composition of solar radiation will change greatly under different seasons and weather conditions. In sunny days, the proportion of direct radiation is large; and in overcast days or when there are thin clouds, the proportion of scattering radiation will increase significantly. These detailed data can completely analyze the composition and change of solar radiation, and by using the dynamic change data, the power generation of photovoltaic power station can be predicted in real time, and more accurate information can be provided for power grid scheduling and energy management.

[0041] In the embodiment, the RS485 interface is used when the transmitter and the environmental monitor transmit data to the inverter data acquisition device, because the differential transmission principle is adopted, the anti-interference ability is strong, the power consumption is low, the cost is low, and the maintenance is easy. The first microcontroller and the second microcontroller are any one of low-power MCU, DSP, ARM, FPGA and single-chip microcomputer, have the advantages of low cost and high stability, and can conveniently realize the collection and transmission of photovoltaic monitoring data.

[0042] In the embodiment, in order to more accurately collect the inclination angle and the azimuth angle of the photovoltaic module, the transmitter is installed at least one of the following positions: the top center of the square support of the mountain photovoltaic module, the joint of the frame of the photovoltaic module, and the connection point after the multiple modules are connected in series.

[0043] 1. The reason for installing the transmitter at the top center of the square bracket of the mountain photovoltaic module is that this position is relatively in the geometric center of the module, which can more accurately reflect the overall attitude of the entire photovoltaic module. From the perspective of inclination monitoring, it can directly obtain the inclination angle of the module plane relative to the horizontal plane. For example, for a north-south arranged photovoltaic array, the transmitter at the top center of the bracket can sense in real time whether the inclination angle of the module changes due to uneven terrain of the mountain or settlement of the bracket foundation and other factors. For the monitoring of azimuth angle, it can accurately judge whether the orientation of the module deviates from the preset best orientation (usually the south direction). In the mountain environment, due to the complex terrain, local mountain shielding or installation errors may occur, causing the azimuth angle of the module to change. Installing the transmitter at this position can timely discover these changes, so as to ensure that the photovoltaic module always receives solar radiation at the best angle and orientation, and improves the power generation efficiency.

[0044] 2. The reason for installing the transmitter at the intersection of the photovoltaic module frame is to facilitate installation and wiring, and at the same time, the structural stability of the frame can be utilized. For example, on some light aluminum alloy frame photovoltaic modules, the transmitter can be fixed at the corner position of the frame intersection through a suitable clamp. From the monitoring effect, it can reflect the changes of inclination and azimuth angles from the edge angle of the module. Moreover, due to its proximity to the edge of the module, it can better sense the angle changes caused by local deformation of the module due to external factors such as wind load and snow load. In mountainous areas, the climate conditions are complex and changeable, and extreme weather conditions such as strong winds and heavy snow may cause the photovoltaic module to deform to some extent. The transmitter installed at the intersection of the frame can timely capture these small angle changes.

[0045] 3. In the mountain photovoltaic system, multiple photovoltaic modules are usually connected in series. Installing the transmitter near the connection point of these module series facilitates the wiring of the transmitter data transmission line together with the electrical connection line of the photovoltaic system, reducing the complexity of line laying. From the monitoring point of view, it can take into account the angle conditions of the subarray composed of multiple modules, because this position is at the key node of the subarray, and the inclination and azimuth angles monitored by it can be used as the representative value of the entire subarray. In the mountain environment, when the photovoltaic system needs to be managed and monitored in sections, the data obtained by the transmitter installed near the series connection point can be used to evaluate the degree of influence of the angle change on the power generation performance of the entire subarray.

[0046] In this embodiment, the environmental monitor is installed on the surface of the photovoltaic module, at the middle position of the inter-row passage of the mountain photovoltaic array, and / or at the edge high point of the photovoltaic area. Specifically:

[0047] 1、The environmental monitor is installed near the surface of the photovoltaic module, which can most directly measure the actual light radiation received by the photovoltaic area, and can simulate the light received by the photovoltaic module itself. Because the light will be affected by many factors such as atmospheric absorption, scattering, reflection, etc. during propagation. Installing near the surface of the module can minimize the differences between the measurement point and the surface of the module, thereby obtaining data closest to the actual light radiation received by the module. For example, in a large mountain photovoltaic power station, due to the undulating terrain, the light angles and intensities received by photovoltaic modules at different locations differ greatly. If the environmental monitor is installed near the surface of the module, for example, at a distance of 0.1-0.2 meters from the surface of the module, the actual light radiation received by the module in each area can be accurately monitored, providing the most accurate data for evaluating the power generation potential of the area.

[0048] 2、In mountainous environments, due to the undulating terrain and the layout of the photovoltaic array, the generation and change of shadows are relatively complex. The monitors installed at the middle and edge high points of the channel can better observe and record the distribution range and movement rules of the shadows. The monitoring of light intensity data at the edge high points of the photovoltaic area can better cooperate with the control unit of the photovoltaic system and can be used as input parameters for the power prediction model of the photovoltaic system. For example, according to the real-time monitoring of light data, combined with the performance parameters of the photovoltaic module, the power generation of the photovoltaic system in the future can be predicted, thereby realizing the optimal scheduling of the photovoltaic system, such as adjusting the working parameters of the inverter, etc.

[0049] Obviously, the above embodiments are only examples for the sake of clarity, and are not limiting of the embodiments. For those skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, all the embodiments need not and cannot be exhausted. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
