The invention provides an automatic temperature control method and system for a single-component thruster for a satellite, and the method comprises the steps: setting three thruster heaters to be in an automatic temperature control mode, and selecting a solenoid valve thermistor as a temperature control point; the automatic temperature control mode comprises an emergency temperature control mode and a normal temperature control mode, the temperature threshold value of the emergency temperature control mode is lower than the temperature threshold value of the normal temperature control mode, and the three thruster heaters adopt the emergency temperature control mode in a default mode; setting self-control temperature control threshold values and automatic temperature control quasi-forbidden states of the three thruster heaters; switching to a normal temperature control mode before a satellite is launched, and setting the on-off state of a single-component thruster heater; when a satellite flies in an in-orbit steady state, one path of heater of the single-component thruster works, and two paths of heaters are arranged before satellite orbit control to work. The problem that the temperature of the electromagnetic valve is too high due to the fact that the thruster is irradiated for a long time in the sun-oriented working mode of the satellite can be solved, and dependence on people during ground testing and on-orbit working of the thruster heater is reduced.

    本发明提供了一种卫星用单组元推力器自动温控方法及系统,包括:将三个推力器加热器设置为自动控温模式,且控温点选择电磁阀热敏电阻;自动控温模式包括应急控温模式和正常控温模式,应急控温模式的温度阈值低于正常控温模式温度阈值,三个推力器加热器默认采用应急控温模式;设置三个推力器加热器的自控控温阈值和自动控温准禁状态;在卫星发射前切换至正常控温模式,对单组元推力器加热器的开关状态进行设置;卫星在轨稳态飞行时单组元推力器加热器维持一路加热器工作,卫星轨控前设置两路加热器工作。本发明能够解决卫星对日定向工作模式时,推力器长期受照引起的电磁阀温度过高问题,减少推力器加热器地面测试和在轨工作时对人的依赖。
