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, which includes multiple sets of independently working lower computer modules working in a cold backup mode, multiple sets of independently working discharge regulation circuits and charge regulation circuits connected to batteries, and a control center . Wherein, the discharge regulation circuit works in the hot backup mode, and the charge regulation circuit works in the cold backup mode. The state of enabling the autonomous operation of the power controller, the state of autonomous management of the charge and discharge power regulation unit, and the state of autonomous power-on of the accidental protection of charge and discharge are enabled. Fault and fault type, and then according to the fault type, execute the corresponding preset command for 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...
