Embodiment Construction

[0089] Such as figure 1 As shown, a spherical concentrator support method for space solar power plants, the specific process is as follows:

[0090] Step 1, use the octahedron to establish a reference polyhedron (see Figure 2A ), the two vertices of the regular octahedron are the poles of the circumscribing sphere, and the other four vertices fall on the equator of the circumscribing sphere;

[0091] Step 2: Map the reference polyhedron obtained in Step 1 to the circumscribed sphere to obtain 8 groups of identical spherical triangles, and select one of them as the basic sub-array such as Figure 2B shown;

[0092] Step 3, divide the basic sub-array

[0093] (3a) Rotate the equatorial circle, cut the midline of the spherical triangle obtained in step (2), and obtain point N i ;

[0094] (3b) Make the node N obtained by step (3a) i The declination circle of , the spherical triangle obtained by cutting step (2), intersects with the side of the spherical triangle at point N...

Description

technical field [0001] The invention belongs to solar energy utilization technology, in particular to a method for supporting a spherical concentrator used in a space solar power station. Background technique [0002] Space solar power plant is a super-large space structure that directly collects and converts sunlight in space, mainly including concentrators, photovoltaic cell arrays, microwave transmitting antennas and other parts. Among them, the scale of the concentrator can reach the kilometer level, which cannot be integrally formed, and must be constructed by splicing unit modules. In 2016, Xidian University proposed the OMEGA (Orb-shapedMembrane Energy Gathering Array) scheme. The plan proposes to build a spherical concentrator with a radius of 1500m by building a support structure according to a certain grid path, and then laying a unidirectional film. [0003] In the field of remote sensing science, the spherical grid system has been studied for many years, mainly...
