The invention provides a satellite adaptive energy self-adjusting thermal control method and system, and relates to the technical field of space flight and aviation, and the method comprises the steps: S1, setting different thermal control modes 1-N according to the temperature control threshold value of an on-satellite heater; s2, judging whether the satellite is in an S3R, BCR or BDR control region based on the on-satellite MEA voltage, and obtaining the output power of an on-satellite solar array, the charging and discharging conditions of a storage battery and the load condition; s3, the voltage sum of the solar panel is calculated, and an energy margin reference voltage value is set; and S4, the satellite program autonomously selects a thermal control mode to control the temperature of the heater according to the energy supply condition. The satellite heat capacity can be utilized to the maximum extent to store energy when the energy in the illumination area is sufficient, thermal control power consumption is reduced when the satellite enters the shadow area or energy crisis occurs, good temperature is provided for the whole satellite, and energy is saved.

    本发明提供了一种卫星适应能源自调节热控方法及系统,涉及航天航空技术领域,包括:步骤S1:根据星上加热器控温阈值高低设置不同的热控模式1~N;步骤S2:基于星上MEA电压判断,卫星处于S3R、BCR、或BDR控制区域,获取星上太阳阵输出功率、蓄电池充放电和负载情况;步骤S3:计算太阳帆板电压和,设置能源余量参考电压值;步骤S4:卫星程序根据能源供给情况,自主选择热控模式进行加热器控温。本发明能够使卫星在光照区能源充足时最大程度利用卫星热容进行储能,当进入阴影区时或出现能源危机时减少热控功率消耗,为整星提供良好的温度,节省能源。
