On the Innovation, Design, Construction, and Experiments of OMEGA-Based SSPS Prototype: The Sun Chasing Article

Baoyan Duan, Yiqun Zhang, Guangda Chen, Ze Zhao, Jianwei Mi, Xun Li, Lin Yang, Xi Li

Engineering doi: 10.1016/j.eng.2023.11.007

Abstract:

 

This study systematically introduces the development of the world's first full-link and full-system ground demonstration and verification system for the OMEGA space solar power satellite (SSPS). First, the OMEGA 2.0 innovation design was proposed. Second, field-coupling theoretical models of sunlight concentration, photoelectric conversion, and transmitting antennas were established, and a systematic optimization design method was proposed. Third, a beam waveform optimization methodology considering both a high beam collection efficiency and a circular stepped beam shape was proposed. Fourth, a control strategy was developed to control the condenser pointing toward the sun while maintaining the transmitting antenna toward the rectenna. Fifth, a high-efficiency heat radiator design method based on bionics and topology optimization was proposed. Sixth, a method for improving the rectenna array’s reception, rectification, and direct current (DC) power synthesis efficiencies is presented. Seventh, high-precision measurement technology for high-accuracy beam-pointing control was developed. Eighth, a smart mechanical structure was designed and developed. Finally, the developed SSPS ground demonstration and verification system has the capacity for sun tracking, a high concentration ratio, photoelectric conversion, microwave conversion and emission, microwave reception, and rectification, and thus satisfactory results were obtained.

Keywords： OMEGA-SSPS     Full-link and full-system Beam collection efficiency     Circular stepped beam shape     Smart structure     Field coupling theoretical model     Beam pointing control
