Problems solved by technology
In addition, due to the geographical limitation of the ground measurement and control station, it is impossible for the ground station to track the satellite in real time in most cases. If the energy system fails in an unmeasurable arc, if measures are not taken in time, the best treatment for the failure may be missed. Timing will eventually lead to the spread of faults, increased losses, and may even endanger the safety of the entire star

The invention discloses an on-orbit autonomous management system of a satellite energy system. The on-orbit autonomous management system comprises a plurality of sets of lower computer modules working in a cold backup mode and working independently, a plurality of sets of discharging adjusting circuits and charging adjusting circuits connected to a storage battery and working independently, and a control center. The discharge adjusting circuit works in a hot backup mode, and the charge adjusting circuit works in a cold backup mode. The power supply controller autonomous operation enabling state, the charging and discharging power adjusting unit autonomous management state and the charging and discharging accident protection autonomous starting-up state are enabled, the control center collects telemetering parameters of the lower computer and the storage battery, compares the telemetering parameters with preset values, judges whether a fault occurs or not and the fault type, and then according to the fault type, executes the corresponding preset instruction to perform autonomous recovery.
Description
technical field [0001] The invention relates to the field of aerospace technology, in particular to an on-orbit autonomous management system and method of a satellite energy system. Background technique [0002] The satellite energy system mainly refers to the generation, change, adjustment and distribution of electric energy, and provides a primary power supply that meets the technical requirements. As an important part of the satellite, it undertakes the task of power supply and distribution for the entire star. The safe and reliable operation of the energy system is an important guarantee for the normal operation of the satellite, and plays a decisive role in improving the performance of the satellite and enhancing the service life of the satellite in orbit. According to the statistical data of spacecraft on-orbit operation failures published at home and abroad in recent years, the energy system has a higher probability of on-orbit failure than other subsystems, and it is...
