摘要
针对大型复杂航天器热控分系统在轨电能源消耗出现较大波动以及峰值功率较大的问题,提出一种基于总功率和温度二元参数耦合进行热控制的新型技术方法。该方法通过对热控电能源消耗值的实时统计监测来顶层控制热控用电部件(如电加热器)的工作状态,使热控电能源消耗值稳定在控制目标值附近,实现热控能源消耗的低值化和稳定化。将其应用到北斗三号IGSO卫星热控分系统中,在轨飞行结果表明:该技术可以有效降低热控用电峰值并减小功率波动,热控峰值功率降低290~360 W,热控总功率波动由±500 W减小到约±100 W。整星能源消耗亦趋于平稳且低值化。
A new thermal control technology based on total power and temperature binary parameters coupling management is proposed in this paper for the large complex spacecraft,which appears large on-orbit fluctuation and peak value in electrical energy consumption of the thermal control subsystem(TCS).In this method,the real-time statistics and monitoring are made on the electrical energy consumption value of TCS,and the thermal control components such as electrical heaters are controlled on top layer,therefore the total power of TCS can be stabilized near the target value and the energy consumption of TCS can be lower and high stable.According to the application in the TCS of Beidou-3 IGSO satellites,on-orbit flight results show that this technology can effectively reduce the peak power consumption and power fluctuation and of TCS,which the peak power reduced 290 to 360 watt and the power fluctuation reduced from±500 watt to nearly±100 watt of TCS in IGSO satellites.In addition,the whole energy consumption of the satellite also tends to be stable.
