摘要
阐述了国内外电源故障、劣化研究的进展,展望了电源系统健康状态与管理的发展趋势。指出建立电源劣化过程的非线性时变行为模型,探求能反映在线电源异常状态的特征量及其获取方法,研究动态预测电源剩余使用寿命算法,已经成为提高电源系统的可靠性、可维护性和安全性的一种新思路。
The highly reliable embedded systems have been widely applied in the fields of aerospace, nuclear power, high-speed rail, etc., which are related to national strategy and security. The reliability of the power supply directly influences the security of the embedded system, and has been the research focus of electronic information and energy. The progress of study about power fault and degradation was summarized in detail, and the developing trend was discussed. It is proposed that the future developing direction main is to build nonlinear time-varying behavior model of degradation process of power, seek and extract the characteristics of the power abnormal state, and study the dynamic prediction algorithm of remaining useful life of the power, which can provide new ideas for improving power system reliability and maintainability.
