摘　　要：超级电容器作为一种长寿命高环境适应性的储能器件,已在配电网上得到使用,其可靠性与长寿命特性得到充分体现,但是由于其低储能密度的特性,往往带来后备时间较短的问题,难以满足更多配电终端需要长时间的备用运行要求。本文以超级电容器为备用电源,从配电终端各功能的功耗与转换电源自身耗损两方面出发,研究了失电情况下采用终端和电源的休眠/唤醒策略来达到大幅提升备用时间的目的,使得备用电源在配网终端上与其他功能部件在长寿命与宽工作温度上完全一致。As a kind of energy storage device with long life and high environmental adaptability,super capacitor has been used in the distribution network,and its reliability and long life characteristics are fully reflected.However,due to its low energy storage density,it often brings the problem of short backup time,which is difficult to meet the long backup operation requirements of more distribution terminals.In this paper,the super capacitor is used as the standby power supply.From the two aspects of the power consumption of each function of the distribution terminal and the consumption of the switching power supply itself,the sleep/wake-up strategy of the terminal and the power supply is used to achieve the purpose of greatly improving the standby time in case of power loss,so that the standby power supply is completely consistent with other functional components in the long life and wide working temperature on the distribution terminal.
