Fully-adjustable unified busbar dual-star combined spacecraft grid-connected power supply and distribution system

Abstract

The invention provides a dual-star combined spacecraft grid-connected power supply and distribution system with fully adjusted unified bus, including: a first spacecraft power supply and distribution system, a second spacecraft power supply and distribution system; wherein each spacecraft power supply and distribution system The electrical system includes solar arrays, battery packs, power controllers, two-way circuit breakers, power distributors, and grid-connected interface units; each spacecraft can supply power to another spacecraft while meeting its own load requirements. Receive the supplementary energy provided by another spacecraft when its own energy is insufficient. The double-star combined spacecraft grid-connected power supply and distribution system with fully regulated unified bus provided by the present invention can not only realize the complementary power supply of the spacecraft when the combined body is working, At the same time, it can also independently supply power to the load when a single spacecraft is running.

Description

technical field [0001] The invention relates to the field of spacecraft power supply and distribution system design, in particular to a grid-connected power supply and distribution system for a dual-star combined spacecraft with a fully regulated and unified busbar. Background technique [0002] After a conventional spacecraft is launched into orbit, it generally does not operate in a combined state during the mission, and its power supply and distribution system is usually powered independently. About 95% of the spacecraft at home and abroad use the independent power supply spacecraft method. Increasingly heavy and rich in exploration targets, especially the development of manned spaceflight, space station, lunar exploration, Mars exploration, planetary exploration, Starlink and other missions, the launch of dual-star combinations has become the preferred method for missions such as deep space exploration. The dual-satellite grid-connected power supply mode is adopted in th...
