Network standby power supply automatic switching method based on intelligent regulation and control system

Abstract

The invention discloses a network backup power supply automatic switching method based on an intelligent regulation and control system, and the method comprises the following steps: S101, charging condition judgment: when an in-station backup power supply fails, firstly detecting whether equipment meets a charging condition or not, then detecting whether the equipment is fully charged or not, then judging whether the network backup power supply automatic switching meets a discharging condition or not, and after the conditions are met, carrying out a discharging action on the network spare power automatic switching device. According to the invention, the implementation of the network spare power automatic switching scheme reduces the links of secondary cable wiring and the like, can flexibly add the function module of the network spare power automatic switching in an automatic system to realize the spare power switching function, and greatly reduces the cost of the spare power automatic switching at the station end. Especially, when the operation transformer substation is subjected to spare power automatic switching transformation, construction wiring can be carried out without corresponding interval power outage, user power supply is not affected, and the operation maintenance management level of the transformer substation is improved. The automatic intelligent level of the transformer substation is improved, dispatching and monitoring are more timely, and the running state of the spare power automatic switching function is mastered finely.

Description

technical field [0001] The invention relates to the technical field of automatic regulation of backup power supplies, in particular to an automatic switching method for network backup power supplies based on an intelligent regulation system. Background technique [0002] At present, due to the limitation of wiring form and communication conditions, some substations are missing backup automatic switching. Substations are protected by automatic switching. At the same time, the automatic switching control strategy of the local backup power supply only considers the bus voltage or incoming current of the local substation, and does not consider factors such as the thermal stability limit of the remote backup power supply side equipment or lines, which may cause the backup power supply to overload and trip, resulting in failure. expand further. [0003] In the maintenance mode, when a fault occurs, such as a power outage in the entire station, there is no means to automatically ...
