Embodiment Construction

[0052] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention, and further detailed description will be given, but the embodiments of the present invention are not limited thereto.

[0053] refer to figure 1 , is a flowchart of the present invention. The goal of satellite energy balance in the present invention is to perform mission operations on a single station and single track, and consume electric energy to achieve energy balance within the single track. Starting from the characteristics of optical imaging small satellites, the present invention firstly combines the requirements of users to customize and calculate the power consumption value of the satellite in a single working mode; then, according to the satellite working mode, the power consumption value (including full load mode) to calculate the total energy consumption...

Abstract

The present invention provides a power consumption budget and energy balance analysis method for optical imaging small satellites. Firstly, combined with user requirements, the satellite power consumption value in a single working mode is custom-calculated; then, according to the satellite working mode, it is reasonable according to the single-track working state Considering the power consumption value, calculate the total energy consumption of satellite single track; according to the selection and design margin of different battery arrays, then calculate the parameters of the solar battery array that meet the energy balance requirements, including the minimum energy of the single track of the solar battery array, the minimum power of the solar battery array, The minimum effective area of ​​the solar cell array, the minimum design area of ​​the solar cell array, the design area of ​​the solar cell array after considering the margin, the effective area of ​​the solar cell array after considering the margin, the power of the solar cell array after considering the margin, and the solar cell array after considering the margin Single rail energy of the solar cell array; finally, calculate the energy demand of the lithium battery pack and select the battery type. This method combines the actual use mode of the satellite, and reasonably completes the analysis of the energy satisfaction degree of the whole satellite.

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.
