Abstract

The invention provides an intelligent energy management and supply method and system for multi-satellite assembly transfer injection. The system comprises a plurality of satellites with independent energy supply, and in the process of transfer injection in an assembly state, according to the conditions of energy which can be provided by a solar array and a storage battery and energy required by the plurality of satellites, energy supply and management are carried out in a grading manner. In the in-orbit operation process, independent energy management is achieved in a load shedding and power supply changing mode, the survivability of coping with a conventional earth shadow period in the assembly orbit transfer process and when energy is insufficient in an abnormal state is improved, and the reliability of the system is improved.

Description

technical field [0001] The invention relates to satellite system design technology, in particular to a method and system for intelligent energy management and supply of a multi-satellite assembly transferred into orbit. Background technique [0002] Generally, the method for a satellite to reach the GEO orbit usually includes carrying the fuel on the satellite body through multiple apogee ignitions or sending the satellite into the GEO orbit by carrying the upper stage. For multi-satellites entering the GEO orbit, the upper stage is mostly used. The upper stage is an autonomous and independent aircraft that does not have solar power generation capabilities. In terms of energy distribution, it can provide power for satellites, and can also provide independent power and management for the satellite's own solar panels. [0003] The invention patent of Wang Lintao et al. "Design method of multi-spacecraft grid-connected power supply system with different voltage systems" (CN201...
