摘要
资源一号02D卫星是我国空基规划的陆地资源遥感卫星,与以往同类卫星相比,具有平台轻量化、多姿态模式、高可靠性特点。文章针对资源一号02D卫星的特点,对供配电分系统的体系结构、技术方案、可靠性设计、自主管理等方面进行了概述,重点论述了卫星供配电分系统基于限频串联顺序开关分流调节(S4R)技术的模块化架构设计、高精度能量平衡设计方案、能源自主管理技术和能源链路高可靠性设计方案。卫星在轨验证结果表明:供配电分系统性能指标优于设计要求,系统设计合理有效。
ZY-1-02D is a remote sensing satellite for land resources in space infrastructure planning.Compared with previous satellites,it has the characteristics of lightweight platform,multi-attitude mode and high reliability.Based on the characteristics of ZY-1-02D satellite,the EPSS(electrical power supply system)structure,technical scheme,reliability design,and independent management are summarized.The modular architecture design based on the frequency limit S4R(sequential serial switch shunt regulator)technology,high-precision energy balance design,energy independent management technology,and energy link high reliability design scheme are focused on in this paper.The on-orbit verification results show that the EPSS performance index is superior to the design requirements,and the system design is reasonable and effective.
