The invention discloses a power distribution network post-fault load recovery method considering minimum duration, which comprises the following steps of: 1, establishing a target function of a power distribution network post-fault load recovery model by taking maximization of weighted load recovery quantity and maximization of minimum duration of a micro-grid as targets; 2, establishing a power distribution network radial constraint by considering the running radial performance of the power distribution network; 3, considering the minimum duration of the micro-grid, and establishing the minimum duration constraint of the micro-grid; 4, mobile emergency power supply vehicle constraints are established; 5, considering operation safety of the power distribution network, and establishing power flow balance and safe operation constraints of the power distribution network; and 6, solving the power distribution network post-fault load recovery model, and obtaining a power distribution network post-fault load recovery scheme. According to the method, the operation safety of the power distribution network is ensured, the problem of unbalanced power flow is avoided, the minimum duration time of the micro-grid and the mobile emergency power supply vehicle are cooperatively considered, the load recovery method after the power distribution network breaks down is effectively obtained, and the power failure loss is reduced.

A router charging circuit and a router using the charging circuit, belonging to the field of communications, include: a transmitting circuit for filtering, regulating, and amplifying the power supply voltage signal; a rectifier and voltage regulator circuit for rectifying and regulating the power supply voltage signal to output a stable current signal; a charging management circuit for real-time detection of the backup power module's power level and sending corresponding control commands to the MCU based on the backup power module's power level; the MCU controlling the transmitting circuit and the rectifier and voltage regulator circuit to perform corresponding operations based on the control commands; and a manual switch connected to the backup power module for turning the backup power module on and off. This invention can prevent power outages and other emergencies by activating the backup power module to provide timely power to the router, ensuring its normal operation.
