摘　　要：空间太阳能电站聚光系统的尺度在千米级,聚光系统的方案设计涉及光、机、电、热及控制等多个学科。现有的空间太阳能电站聚光系统的设计方案不同程度上存在太阳光收集效率低、收集功率波动大、聚光系统质量高、控制系统复杂等不足。因此,需要综合考虑各种因素,提出高效、稳定、轻质和控制简单的聚光系统设计方案。文章对SSPS-ALPHA方案的聚光系统作了深入分析,并基于与ALPHA方案相同的能量传输假设,针对ALPHA方案的不足提出了一种新的聚光系统设计方案,称之为SSPS-OMEGA方案。通过比对分析,在与ALPHA聚光方案相同收集功率的前提下,OMEGA聚光方案不仅可以高效、稳定地收集太阳光,而且OMEGA方案的功率质量比比ALPHA方案提升了31.68%。The concentrator system of the space solar power station（SSPS）has a dimension of km scale, which requires the knowledge of optics, mechanics,thermology,control,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%.
