Example Embodiment

[0024] In view of the shortcomings of the prior art, the present invention proposes a method and system for rapid power synthesis of spacecraft based on flight procedures, which solves the existing method of relying on manual tabulation of power statistics, because flight procedures are adjusted, equipment is switched on and off, and working modes occur. Changes, orbits and attitude adjustments bring about problems such as large workload, low efficiency and high error rate in power statistics, such as figure 1 Shown is a flow chart of a spacecraft power rapid synthesis method based on flight procedures. The method of the present invention includes the following steps:

[0025] Step 1: Obtain the time-flight event table of the spacecraft (refer to the spacecraft flight procedure). The spacecraft flight procedure is designed to achieve the mission of the spacecraft, which stipulates the spacecraft from launch to on-orbit flight to mission in chronological order All instructions and ...

Abstract

The invention discloses a flight program-based spacecraft power quick synthesis method and system. The method comprises the steps of firstly obtaining power-on/power-off and working mode information, sorted according to time, of all power devices of a spacecraft and power consumption values corresponding to the working modes of all the power devices, and obtaining output power, in a direct solar radiation condition, of a solar wing of the spacecraft and an incident angle, changed with the time, of the solar wing; secondly establishing mapping relationships between the power consumption values of all the power devices of sub-systems and the time, and then obtaining a mapping relationship between load power of the spacecraft and the time, and a mapping relationship between actual output power of the solar wing of the spacecraft and the time; and finally finishing energy balance calculation of the spacecraft according to the mapping relationship between the load power of the spacecraft and the time, and the mapping relationship between the actual output power of the solar wing and the time.

Description

technical field [0001] The invention relates to the field of spacecraft power synthesis, in particular to a method and system for fast synthesis of spacecraft power based on flight procedures. Background technique [0002] The existing spacecraft power demand statistics method is to organize a two-dimensional table, fill in the flight events and occurrence time according to the flight program in the header of the row table, and fill in the name of each subsystem and electrical equipment in the header of the column, and manually enter the power consumption of the equipment in each flight stage. Then add up the load power consumption of the spacecraft; at the same time, according to the incidence angle of the solar wing and the direct output power of the solar wing at each flight stage, the output power of the solar wing at each flight stage is obtained, and then manually calculate the load power consumption of the spacecraft and the output power of the solar wing according to ...
