The concentrator system of the space solar power station (SSPS) has a dimension of km scale, which requires the knowledge of optics, mechanics, thermology, ontrol, and other disciplines. The existing concentrator schemes of the SSPS, such as the SSPS-ALPHA scheme, have the disadvantages of low efficiency and/or large fluctuation in solar concentration, large mass, and complicated control system. Thus,the SSPS scheme with high efficiency, light weight and simple control strategy was proposed. The SSPS-ALPHA scheme was analyzed, and then a new scheme called SSPS-OMEGA was presented under the premise of the same power hypothesis with the ALPHA scheme. With the same power collection of the ALPHA scheme, the proposed scheme has higher and more stable solar concentration efficiency, and the power-mass ratio is higher with 31.68%.
