Abstract

The invention discloses a space low-rail high-voltage power supply system supporting on-rail maintenance, and belongs to the technical field of space power supplies. The system comprises two independent power channels, the two power channels have the same function composition, and energy is provided for a spacecraft load through energy grid connection; each power channel takes the solar cell wing as a starting point and the bus filter as an end point to form an independent 100V power supply bus; each power channel comprises a solar cell wing, a driving mechanism, a shunt regulator, a bus filter, a comprehensive driving controller, a charging and discharging regulator, a lithium ion storage battery pack and a power manager; and the solar cell wing, the shunt regulator, the bus filter, the comprehensive driving controller, the charging and discharging regulator, the lithium ion storage battery pack and the power manager are minimum replaceable units (ORU). Under the condition that related products of the power supply system break down, astronauts carry out on-orbit maintenance operation, and the service life of the power supply system is prolonged.

Description

technical field [0001] The invention relates to a space low-rail high-voltage power supply system supporting on-orbit maintenance, and belongs to the technical field of space power supplies. Background technique [0002] In the early space projects, the mission time of the aerospace system was short, the power was small, the system was relatively simple, and it was constrained by human activities outside the earth. The usual practice was to use high-reliability (zero) components or a large number of redundant designs and on-orbit backup to achieve high availability and high safety of the spacecraft. With the development of the third phase of my country's manned spaceflight, my country will build a long-term manned space station. The space station is different from any previous in-orbit aircraft in our country. It is a manned aircraft with long life, high reliability, high voltage and high power, and the system is more complicated. In order to achieve its 15-year long-life ...
