Abstract

The invention provides a space solar energy power station, which comprises a light concentrator, solar energy cell arrays, a microwave emission antenna, traction ropes and a transmission cable. The topology of the light concentrator consists of an upper part annular sphere, a middle part annular sphere and a lower part annular sphere connected together wherein the radius of curvature of the middle part annular sphere is greater than those of the upper part annular sphere and the lower part annular sphere. The solar energy cell arrays are located in the central rings of the upper part, the middle part and the lower part and are connected with these parts through sliding pairs and rotate around the microwave emission antenna. The microwave emission antenna is connected with the outer frames at the upper edge and the lower edge of the light concentrator through six traction ropes. The solar energy cell arrays are electrically connected with the microwave emission antenna through a conductive structure and the power transmission able. The space solar energy power station of the invention increases the utilization efficiency of the light concentrator, and the power-mass-ratio of the space solar energy power station is further increased while the design difficulty for a heat radiation system is reduced.

Description

technical field [0001] The invention belongs to the technical field of space solar power plants and provides an improved OMEGA-SSPS space solar power plant solution. Background technique [0002] Due to the increasing requirements of human beings on the living environment, countries all over the world are increasing the research and use of clean energy. Space solar power station (SSPS, Space solar power station) attracts more and more domestic and foreign experts to study because of its unique advantages. Many SSPS schemes have been proposed, but the Mankins scheme and the quadratic symmetric concentrating scheme proposed in recent years have attracted widespread attention because of their modularity, high concentration ratio, and feasibility. [0003] The Space Solar Power Plant Research Office of Xidian University proposed an OMEGA-SSPS (Orb-shape Membrane Energy Gathering Array, OMEGA) scheme, which is composed of a concentrator, a battery array, a conductive system and ...
