Optical imaging minisatellite power dissipation budgeting and energy balance analysis method

Abstract

The invention provides an optical imaging minisatellite power dissipation budgeting and energy balance analysis method. The method comprises the steps that firstly, on the basis of the using requirement of a user, the satellite power dissipation value under each working mode is calculated in a self-defined mode; then, according to the satellite working mode, the power dissipation value is reasonably considered according to the monorail working state, and the total energy dissipation of satellite monorail is calculated; according to the model selection of different battery arrays and design margin, and then, solar battery array parameters meeting the energy balance requirement are calculated and include solar battery array monorail minimum energy, solar battery array minimum power, solar battery array minimum effective area, solar battery array minimum design area, solar battery array design area obtained after margin is considered, solar battery array effective area obtained after margin is considered, solar battery array power obtained after margin is considered, and solar battery array monorail energy obtained after the margin is considered; finally, the energy requirement for the lithium battery pack is calculated, and battery model selection is performed. According to the method, on the basis of the actual using mode of satellites, whole-satellite energy satisfaction degreeanalysis is reasonably completed.

Description

technical field [0001] The invention relates to the field of spacecraft design, in particular to a power consumption budget and energy balance analysis method for optical imaging small satellites. Background technique [0002] Satellite power budget and energy balance analysis is a very important part of the overall satellite design, which determines whether the satellite energy system design can meet the use requirements. The power consumption budget and energy balance analysis involves satellite power requirements, satellite orbit parameters (illumination conditions), satellite working modes and payload mission planning, etc. In the overall satellite design stage, according to different satellite missions, functions, and usage requirements, there are many uncertainties in power budget and energy balance analysis, so it is difficult to give a standard satellite power budget and energy balance analysis method, so there is little published literature in this area.
