Abstract

The invention belongs to the field of power sources, and relates to a satellite power system, in particular to a quickly-integrated satellite power system which solves the problem that an existing satellite power system is poor in system compatibility. The system comprises a storage battery pack, a solar battery array and a power control and distributing unit. The storage battery pack is used for supplying power for load of a whole satellite and the power control and distributing unit, the solar batter array is used for converting received light energy to electric energy to charge the storage battery pack, the solar battery array is connected with the power control and distributing unit through an electric connector, the solar battery array comprises n solar batteries which are connected in series or in parallel through wires, and n is an integer which is larger than or equal to 2. The quickly-integrated satellite power system is suitable for charging satellites.

Description

technical field [0001] The invention belongs to the field of power supply, and relates to a satellite power supply system. Background technique [0002] With the development of space technology, military operations and frequent large-scale natural disaster relief are increasingly dependent on various satellites, which puts forward high requirements on the rapid response capability of satellites. At present, relevant research is being carried out internationally. For example, in 2007, the U.S. Department of Defense formally submitted a report on the development of the "Space Rapid Response Operations" ORS program to the Congressional Defense Committee, and has successively launched a number of rapid response satellites in recent years. Such as TacSat-1, TacSat-2, ORSSat-1. [0003] The satellite power system provides safe and reliable power guarantee for the normal operation of other subsystems and payloads of the satellite. Designing a satellite power system with rapid int...
