摘要
卫星动力分系统是卫星的关键分系统之一。电力子系统的作用是产生、储存和分配有条件的电力给各个子系统。研究了基于COTS的小卫星电力系统的模块化设计方法。SPS主要由五个部分组成:发电单元PGU (Power generation Unit)、电池单元BTU (Battery Unit)、电源控制单元PCU (Power Control Unit)、电源调节单元PCNU (Power conditioning Unit)和配电单元PDU (Power Distribution Unit)。根据任务要求，采用模块化的方法开发了集中式、全规范的总线体系结构。SPS可从200瓦扩展到1000瓦。它的目标是实验性的低地球轨道任务。任务期限为一年。
Modular & COTS based power system for small LEO satellite
Satellite Power subsystem is one of the critical subsystems of satellite. The purpose of power subsystem is to generate, store and distribute the conditioned power to all subsystems. This paper focuses on modular design methodology of COTS based small Satellite Power System (SPS). SPS has five main parts Power generation Unit (PGU), Battery Unit (BTU), Power Control Unit (PCU), Power conditioning Unit (PCNU) and Power Distribution Unit (PDU). According to the mission requirements centralized, fully regulated bus architecture is developed using modular approach. The SPS is scalable starting from 200 watt to 1000 watt. It is aimed for experimental LEO mission. The duration of the mission is one year.
