[0036] The principles and features of the present application are described below. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0037] Climate change is a global problem facing mankind. With the emission of carbon dioxide in various countries, greenhouse gases have soared, posing a threat to life systems. Against this background, countries around the world are reducing greenhouse gas emissions through global agreements. Photovoltaic power generation projects are engineering projects that use solar photovoltaic power generation technology to convert solar energy into electrical energy. Photovoltaic systems include photovoltaic modules, inverters, support systems and monitoring systems. Photovoltaic modules include solar panels, which are used to convert solar energy into electrical energy. Inverters convert the direct current generated by photovoltaic modules into alternating current for use in the power grid. Support systems are used to support photovoltaic modules to ensure their stability and optimal angle. Monitoring systems monitor and manage the operation of photovoltaic power stations to ensure efficient operation and timely maintenance.

[0038] The support system can be a flat single-axis photovoltaic support.

[0039] The flat single-axis photovoltaic support is a support structure used in solar photovoltaic projects. It is mainly used to track the trajectory of the sun. It can automatically adjust the east-west angle of the photovoltaic support to maximize the absorption of solar energy to improve the power generation efficiency of photovoltaic modules. This tracking system is usually adjusted multiple times a day according to different solar trajectories to adapt to the movement of the sun from east to west. The flat single-axis support consists of a flat single-axis photovoltaic support, a rotation mechanism and a control system.

[0040] In some embodiments, a flat single-axis photovoltaic support includes a support column, a rotating shaft, a drive system, and a photovoltaic module bracket, which is installed on the ground and allows the photovoltaic module to rotate around a single horizontal axis to track the movement of the sun. The flat single-axis photovoltaic support system is driven by a motor or a hydraulic system to adjust the angle of the photovoltaic module so that it always faces the sun, thereby maximizing the capture of solar energy.

[0041] Compared to fixed brackets, flat single-axis bracket systems require more land space because the bracket system needs space to rotate and adjust the angle.

[0042] The embodiment of the present application provides a method for setting a flat single-axis photovoltaic bracket, which can realize the preliminary land use analysis of the flat single-axis photovoltaic bracket, and determine the installation parameters of the bracket according to the geographical location and the main parameters of the photovoltaic components used. For example, the left and right installation spacing between brackets, the number of acres of land per megawatt when arranged in a single row, or the number of acres of land per megawatt when arranged in a double row. Thereby, the layout efficiency of the bracket system is improved.

[0043] In some embodiments, the flat single-axis photovoltaic bracket setting system provided in the embodiments of the present application is suitable for flat ground or a slope with an inclination angle less than or equal to 5°.

[0044] The embodiment of the present application provides a system for setting up a flat single-axis photovoltaic bracket, which can execute the method for setting up a flat single-axis photovoltaic bracket provided in the embodiment of the present application.

[0047] S1, based on the latitude, calculate the declination angle.

[0048] According to the setting position of the flat single-axis photovoltaic bracket, determine the longitude and latitude of the center point of the flat single-axis photovoltaic bracket.

[0049] In some embodiments, the calculation formula of the declination angle δ is:

[0050]

[0051] Among them, N1 is the number of days from the vernal equinox to the summer solstice; α1 is the number of days counted from the vernal equinox; N2 is the number of days from the summer solstice to the autumnal equinox; α2 is the number of days counted from the vernal equinox; N3 is the number of days from the autumnal equinox to the winter solstice; α3 is the number of days counted from the vernal equinox; N4 is the number of days from the winter solstice to the vernal equinox; α4 is the number of days counted from the winter solstice.

[0052] In one implementation, N1 = 92.975, N2 = 93.629, N3 = 89.865, and N4 = 89.012.

[0053] Exemplarily, on the winter solstice (December 22) from 9:00 to 15:00 (local true solar time), the declination angle δ of the setting position of the flat single-axis photovoltaic bracket on the winter solstice is calculated based on the land area per megawatt (the unit of land area is: mu). The winter solstice is the day with the shortest daylight hours and the longest night in all parts of the northern hemisphere, and the solar altitude angle is the smallest on the winter solstice. True solar time is obtained by observing the center of the sun's apparent disk, that is, when the sun is due south every day (noon) is 12 noon. True solar time is also called apparent solar time, or apparent time for short.

[0063] In some embodiments, the calculation formula of the hour angle ws is:

[0064] cosws=-tanφtanδ;

[0065] Among them, φ represents the zenith angle and latitude; δ represents the declination angle.

[0066] S5, based on the solar altitude angle, the azimuth angle, the east-west width of the target, and the tracking angle of the flat single-axis bracket, the left-right spacing of the installation component is obtained.

[0067] According to the installation position of the flat single-axis photovoltaic bracket, determine the tracking angle and the east-west width of the flat single-axis bracket.

[0068] In some embodiments, the left-right spacing is calculated as follows:

[0069] D=K*cosA+K*sinA*cos(90°-γs) / tanαs;

[0072] The setting results include the area occupied by a single row or double row per megawatt.

[0073] According to the setting position of the flat single-axis photovoltaic bracket, confirm the number of component rows, component length, motor reservation and motor reservation.

[0074] In some embodiments, the calculation formula for the number of acres occupied by each megawatt of the single-row or double-row is:

[0075] S=(L*R+Y*(R-1)+X1+X2)*(K*cosA)

[0076] Among them, R represents the number of rows of photovoltaic modules; L represents the horizontal length of the photovoltaic module when the photovoltaic module is installed; X1 represents the reserve for the motor in the flat single-axis system; X2 represents the reserved gap between the north and south rows of flat single-axis brackets; Y represents the installation gap of the photovoltaic module; K represents the east-west width of the square, and A represents the tracking angle of the flat single-axis bracket.

[0077] In one implementation, Y represents the installation gap of the photovoltaic module, which may be 20 mm.

[0078] like Figure 3 As shown, A is the tracking angle of the flat single-axis bracket, D1 is the horizontal projection distance of the flat single-axis bracket, D2 is the east-west shadow length of the sun's rays passing through the highest point of the flat single-axis, and α is the solar altitude angle.

Calculation is based on 12:00 on the winter solstice.
