空间电源故障轻则影响航天器的工作寿命,重则导致航天灾难,空间电源是航天器的心脏,目前对于航天器的故障诊断主要是依靠人机结合的地面诊断系统,但其实时性难以保证,且当航天器通信系统故障时,地面诊断系统将毫无作用,因此,在空间电源的设计过程中,一方面通过采用软硬件冗余的方式提高其可靠性,另一方面,需要研究开发空间电源的智能故障诊断技术,能保证航天器在轨可靠运行。
Space power failure, on the other hand, affects the working life of the spacecraft, and leads to the space disaster. The space power is the heart of the spacecraft. At present, the fault diagnosis of the spacecraft relies mainly on the human-machine ground diagnosis system, but its real-time nature is difficult to guarantee , And when the spacecraft communication system fails, the ground diagnosis system will have no effect. Therefore, in the design of space power supply, on the one hand, the reliability of the space power supply system is improved by means of hardware and software redundancy; on the other hand, research and development Space power intelligent fault diagnosis technology to ensure the reliable operation of spacecraft in orbit.
