摘 要:以用于空间太阳能电站的远距离、大功率激光无线能量传输为研究背景,以提高系统能量传输效率为宗旨,针对多光束传输的激光无线能量传输系统协同捕获、瞄准与跟踪(APT)方法进行研究。首先通过对大功率激光无线能量传输系统的分析,获知了单光束激光无线能量传输系统的局限性,然后针对大功率、多光束激光无线能量传输系统的协同APT系统组成,分析了单终端多光束系统和多终端多光束系统的实现方法及构成,最后针对单光束、7光束和9光束发射系统的目标重构光斑进行仿真,仿真结果表明,通过精确的多光束协同APT系统可以实现光束重构,重构后的能量光斑能量密度和分布都能得到改善。文章的研究成果将为建造用于空间太阳能电站的大功率、远距离激光能量传输系统提供技术储备和理论依据。
The scientists from many countries and areas study the solar power satellite (SPS), which could provide clean energy. This paper, which belongs to the field of the laser wireless power transmission for the SPS, studies the method of the cooperative APT(the cooperative ac- quisition, pointing and tracking) in multiple-beam laser wireless power transmission system in or der to improve the transmission efficiency. Firstly, the weakness of single-beam laser wireless power transmission system is analyzed. Secondly, the APT system is introduced, and then the formation and the algorithm of the cooperative APT system for multiple-beam are studied. At last the simulation for one beam, seven beams and nine beams is made. Based on this paper, the method of cooperative APT in the multiple-beam transmission utilized is found, and it will be the theoretical basis and design support of the laser wireless power transmission system for space so- lar power satellite.
