摘要

Based on the existing conceptual design scheme for Space Solar Power Stations (SSPS), this paper proposes a new scheme, the Collapsible Multi-Transmission System of SSPS (CMTS-SSPS). It gives the overall conceptual configuration and the preliminary design scheme of each power station system. By analyzing the advantages and disadvantages of various sun-oriented non-aggregated sunshine SSPS in terms of design configuration, operation principle, main functions, construction, and launch process, the scheme proposes the design objectives of new Space Solar Power Stations. At the same time, a reasonable numerical prediction is made according to the existing technical basis. The design ideas of functional modules related to the process of "Collection-Transmission-Storage-Utilization" of SSPS energy are given. Compared with other space solar power stations, CMTS-SSPS has both microwave and laser emission functions, which can provide powerful support for neighboring satellite systems by using laser transmitters based on realizing satellite-ground wireless energy transmission and ensuring the stability of power supply for satellite systems. In addition, CMTS-SSPS adopts the two-dimensional unfolding technology for Solar Cell Array and Microwave Transmitting Antenna Array. The technology can realize SSPS loaded and launched by a heavy lift launch vehicle, avoiding the complex operation of traditional SSPS, which needs to be dismantled into modules and launched into orbit for on-orbit assembly, significantly improving the overall reliability of SSPS.
