Description

Technical Field

[0001] The present invention belongs to the technical field of space solar power stations, and particularly relates to a method, device, and electronic equipment for configuring the receiving surface of a concentrating photovoltaic cell array. Background Art

[0002] Sustainable energy is crucial for human energy supply and its importance will continue to increase. Space solar power stations provide an important direction for future sustainable energy supply. Space solar power stations collect light energy in space, convert it into electrical energy, and then transmit it back to the ground via microwaves and finally convert it into usable electrical energy. Among existing light energy collection schemes, spherical concentration has received wide attention due to its unique characteristics of a rotating body. The characteristic of spherical light concentration is that light energy is concentrated on a cylindrical receiving surface with a radius half of the radius perpendicular to the center and the bottom vertex of the sphere. When using a cylindrical receiving surface for reception, the light intensity in the direction of its rotational symmetry is equal, but the light distribution in the direction perpendicular to the rotational symmetry axis varies greatly. For the design of the photovoltaic cell array of a space solar power station, the better the uniformity of the light distribution on the receiving surface, the simpler and more efficient the series-parallel design of the photovoltaic cell array, and the higher the electrical energy output by its photoelectric conversion.

[0047] The following further describes the present invention in detail with reference to specific embodiments, but the embodiments of the present invention are not limited thereto.

[0048] To solve the problems of slow calculation speed, high calculation complexity and low accuracy existing in the existing receiving surface configuration method, an embodiment of the present invention provides a receiving surface configuration method for a concentrating photovoltaic cell array. Refer to Figure 1 , Figure 1 which is a schematic flow chart of a receiving surface configuration method for a concentrating photovoltaic cell array provided by an embodiment of the present invention, and specifically includes the following steps:

[0049] Step S101, rotate the initially preset bus bar around the central axis for one week to obtain the initial receiving surface of the concentrating photovoltaic cell array; the central axis is the axis perpendicular to the center of the spherical reflecting surface of the concentrating photovoltaic cell array.

[0050] In an embodiment of the present invention, a concentrating photovoltaic cell array correspondingly includes a spherical reflecting surface, and the axis perpendicular to the center of the spherical reflecting surface of the concentrating photovoltaic cell array is the central axis, which can be understood as that the spherical reflecting surface is rotationally symmetric about the central axis.

[0051] Rotate the initially preset bus bar around the central axis for one week to obtain the initial receiving surface of the concentrating photovoltaic cell array. Among them, the initially preset bus bar can be any bus bar, and the initial receiving surface refers to the receiving surface formed by rotating any bus bar, that is, the initial receiving surface is also rotationally symmetric about the central axis.

[0052] Step S102, perform spherical concentrating operation based on the initial receiving surface to obtain the light intensity model corresponding to the initially preset bus bar.

[0053] Refer to Figure 2 , Figure 2 which is a schematic diagram of a spherical concentrating micro-segment provided by an embodiment of the present invention. A coordinate system is established with the center of the spherical reflecting surface as the origin O, where the z-axis is the central axis, 101 represents the spherical reflecting surface, and 102 represents the receiving surface. On this basis, the spherical equation of the spherical reflecting surface is:

[0054] x 2 +y 2 +(z - R) 2 =R 2 ;

[0055] where (x, y, z) are the coordinates of any point on the reflecting surface, (0, 0, R) is the center coordinate of the sphere, and R is the radius of the sphere.

[0056] Assume the bus bar function is:

[0057]

[0058] where z r represents the ordinate of the receiving surface position point; x r represents the abscissa of the receiving surface position point; represents the bus bar function, through a series of xr and z r A busbar can be determined.

[0059] The light is incident from the direction perpendicular to the aperture plane, that is, from the direction perpendicular to the xy plane. According to the correspondence between the microelement segments, see Figure 3 , Figure 3 is a schematic diagram of a spherical focusing aperture surface provided by an embodiment of the present invention, the length of dx, the length of dl and dl r The light energy on the length is equal, dx is the distance on the x-axis corresponding to the position point of the reflection surface, dl is the distance on the reflection surface corresponding to the position point of the reflection surface, dl r It is a distance corresponding to the receiving surface position point on the receiving surface, which can be understood as the busbar segment. Figure 3 2πx r dθdl r The total light energy of the segment is equal to the total light energy corresponding to the 2πxdθdx segment of the aperture surface. Let I 0 is the light intensity at the incident aperture surface, the light intensity model corresponding to the initial busbar is:

[0060]

[0061] Among them, φ(x r ) represents x r At this time, the light intensity value is the light intensity value on the light energy distribution function preset at the initial stage; φ(·) represents the light energy distribution function; express The derivative of represents the generatrix function; x r represents the horizontal coordinate of the receiving surface position point; x represents the horizontal coordinate of the reflecting surface position point; f(x) represents the corresponding relationship between the reflecting surface position point and the receiving surface position point; f'(x) represents the derivative of f(x).

[0062] In the embodiment of the present invention, the relationship between the position point of the reflection surface and the position point of the receiving surface can be obtained by combining the reflected light and the generatrix function:

[0063]

[0064] Wherein, α is the cosine angle of the incident angle of the reflection surface at normal incidence, and z represents the coordinate of the position point of the reflection surface on the z-axis.

[0065] On this basis, the relationship between the reflective surface position point and the receiving surface position point can be expressed as follows:

[0066] x r =f(x);

[0067] Step S103: For the light intensity model, perform an operation of balancing the light distribution with a preset light intensity value to obtain the differential equation of the receiving surface bus.

[0068] In the embodiment of the present invention, assuming that the bus is unknown, in order to balance the light distribution, the differential equation of the receiving surface bus can be obtained by giving a light intensity value.

[0069] Specifically, to obtain an equal light intensity distribution, the light intensity value on each bus segment in the bus is a fixed value, that is is a self - given preset concentration ratio. The concentration ratio refers to the ratio of the central light intensity to the peripheral light intensity of the light beam. By giving the concentration ratio, the light intensity value can be given. Then the equal light intensity bus function satisfies the following relationship:

[0070]

[0071] Among them, The value of can be selected by those skilled in the art according to experience and is not limited here.

[0072] The equal light intensity bus function can be specifically expressed as:

[0073]

[0074] Substitute α into the equal light intensity bus function, and we can get:

[0075]

[0076] Denote f'(x) as Then the differential equation of the receiving surface bus is:

[0077]

[0078] So far, the differential equation of the receiving surface bus is obtained.

[0079] Step S104: Under different concentration ratios, use the differential equation solving method to solve the differential equation of the receiving surface bus to obtain multiple bus segments corresponding to different concentration ratios.

[0080] In the embodiment of the present invention, a series of x r can be obtained by solving the differential equation of the receiving surface bus. According to x r and a series of corresponding z r can be obtained. Using one x r and a corresponding z r can determine a bus segment. There are multiple bus segments in the bus. r In the bus, there are multiple bus segments.

[0081] For a concentration ratio, by using the differential equation solving method to solve the differential equation of the receiving surface generatrix, multiple generatrix segments corresponding to this concentration ratio can be obtained. Then, performing this operation for multiple concentration ratios respectively can obtain multiple generatrix segments corresponding to different concentration ratios.

[0082] In one implementation, for discrete nodes, x r1 <x r2 <…<x rn , where n is the total number of receiving surface position points. By using the numerical solution method of the differential equation, the corresponding approximate values z r1 <z r2 <…<z rn can be obtained. Among them, the differential equation solving method includes the numerical solution method, the fourth-order Runge-Kutta solving method, or the optimization solving method. In the embodiments of the present invention, in order to improve the calculation accuracy, the fourth-order Runge-Kutta solving method is preferably used.

[0083] Step S105: For each concentration ratio, integrate multiple generatrix segments corresponding to this concentration ratio to obtain the isointensity generatrix corresponding to this concentration ratio.

[0084] In the embodiments of the present invention, for each concentration ratio, integrating multiple generatrix segments corresponding to this concentration ratio to obtain the isointensity generatrix corresponding to this concentration ratio includes:

[0085] For the generatrix segments with overlapping parts among multiple generatrix segments corresponding to each concentration ratio, use the median method to perform curve fitting to obtain the fitted generatrix;

[0086] Integrate multiple non-overlapping generatrix segments and the fitted generatrix corresponding to each concentration ratio to obtain the isointensity generatrix corresponding to this concentration ratio.

[0087] In the embodiments of the present invention, for each concentration ratio, for the entire spherical reflecting surface, by balancing the light distribution on the receiving surface and integrating the generatrix segments in each region, the isointensity generatrix can be obtained. Refer to Figure 4 , Figure 4 is a schematic diagram of the isointensity generatrix configuration corresponding to the sub-region reflecting surface provided by the embodiments of the present invention. Analyze the generatrix segments. For example, Figure 4 if there are two generatrix segments with overlapping parts, take out the overlapping part in the x-axis direction, for the corresponding values on the z-axis, use the median method to obtain the key points, and then perform curve fitting based on these key points to obtain a relatively isointense generatrix as the fitted generatrix. Among them, the method for obtaining the key points on the z-axis can also include the quadratic interpolation method, etc., which is not limited here.

[0088] Then, for each concentration ratio, integrate multiple non-overlapping generatrix segments and the fitted generatrix corresponding to this concentration ratio to obtain an isointensity generatrix. Refer to Figure 5 , Figure 5It is a schematic diagram of the integrated equal - intensity busbar provided by an embodiment of the present invention.

[0089] In one implementation, different concentration ratios include integer - multiple concentration ratios or decimal - multiple concentration ratios. Specifically, different concentration ratios can include, but are not limited to, 2 - fold concentration ratio, 3 - fold concentration ratio, 4 - fold concentration ratio, 5 - fold concentration ratio, or 6 - fold concentration ratio, and can also be any decimal - multiple concentration ratio. Different concentration ratios take into account different types of photovoltaic cell arrays, making it more convenient for scenario applications under different concentration ratios. Refer to Figure 6 , Figure 6 It is a schematic diagram of the equal - intensity busbar corresponding to different concentration ratios provided by an embodiment of the present invention. For the 2 - fold concentration ratio, 3 - fold concentration ratio, 4 - fold concentration ratio, 5 - fold concentration ratio, or 6 - fold concentration ratio, an equal - intensity busbar can be obtained respectively.

[0090] Step S106: Rotate the equal - intensity busbars corresponding to different concentration ratios around the central axis for one week to obtain the receiving - surface configuration results under different concentration ratios.

[0091] For each concentration ratio, after obtaining the equal - intensity busbar, rotating the equal - intensity busbar around the central axis for one week can obtain the receiving - surface configuration result with good light distribution uniformity.

[0092] In the embodiment of the present invention, through a preset light - intensity value, the light - intensity model is operated for balanced light distribution to obtain the differential equation of the receiving - surface busbar. Then, multiple busbar segments directly obtained by solving the differential equation of the receiving - surface busbar are integrated to obtain the equal - intensity busbar. The receiving - surface configuration method provided by the present invention gives a clear mathematical model, avoiding complex iterative calculations, with low computational complexity and high computational speed. At the same time, the accuracy of the equal - intensity busbar is improved by the segmented acquisition method, thereby enhancing the light - distribution uniformity of the receiving - surface configuration result and improving the photoelectric conversion performance of the concentrating photovoltaic cell array.

[0093] In addition, by calculating the equal - intensity busbars under different concentration ratios, the receiving - surface configuration results under different concentration ratios can be obtained, which is more convenient for subsequent applications of the receiving - surface configuration under different concentration ratios.

[0094] Based on the same inventive concept, an embodiment of the present invention also provides a receiving - surface configuration device for a concentrating photovoltaic cell array. Refer to Figure 7 , Figure 7 It is a schematic structural diagram of a receiving - surface configuration device for a concentrating photovoltaic cell array provided by an embodiment of the present invention.
