Non-measurement-and-control arc segment shadow period thermal control compensation power saving method and system

Abstract

The invention provides a non-measurement-and-control arc segment shadow period thermal control compensation power saving method. The method comprises the steps of 1, determining a satellite illumination period heater state and a shadow period heater state through thermal simulation, 2, in the satellite measurement and control arc section, sending a thermal control heater program control forbiddinginstruction and a thermal control heater state setting instruction according to the illumination period heater state, 3, sending a delay instruction with a time code according to the shadow time forecast and the shadow period heater state of the non-measurement-and-control arc section before the satellite goes out of the measurement-and-control arc section and enters the non-measurement-and-control arc section, and respectively setting the thermal control heater states of the non-measurement-and-control arc section when the non-measurement-and-control arc section goes into the shadow and goesout of the shadow, and 4, after the non-measurement-and-control arc section is finished and the satellite enters the measurement-and-control arc section again, sending a program control permission instruction of the thermal control heater, and carrying out closed-loop control on the heater according to a threshold value. Thus, the thermal control compensation power of the satellite in the shadowperiod is effectively saved, and the over-discharge risk of the storage battery is greatly reduced.

Description

technical field [0001] The present invention relates to the field of satellite technology, in particular to a method and system for saving power by thermal control compensation during the shadow period of a non-measurement and control arc segment. In particular, it relates to a power saving method for thermal control compensation during the shadow period of a satellite non-measurement and control arc. Background technique [0002] During the light period of the satellite in orbit, the solar battery array equipped with the star can provide energy for the whole star; while in the shadow period, the battery needs to meet the power consumption demand of the whole star. However, with the development of spaceflight, it is urgent to optimize resources such as the weight and power consumption of satellites. The weight of batteries is also strictly controlled, and their power generation is also reduced accordingly. During the shadow period, the satellite has no light, and the therma...

AI Technical Summary

Problems solved by technology

During the shadow period, the satellite has no light, and the thermal control compensation power increases, which forms an irreconcilable contradiction with the decrease of battery capacity

In addition, in the non-measurement and control arc section, the satellite command cannot go up, and the thermal compensation heater cannot be effectively controlled. The increased burden on the battery during the shadow period also increases the risk of battery over-discharge.
