Intelligent operation and maintenance and anti-error management and control system and method for secondary pressing plate of transformer substation

Abstract

The invention discloses an intelligent operation and maintenance and anti-error management and control system and method for a secondary pressing plate of a transformer substation, and belongs to the technical field of secondary pressing plate management. The technical problem to be solved is to provide the improvement of the hardware structure of the intelligent operation and maintenance and anti-error management and control system for the secondary pressing plate of the transformer substation. According to the technical scheme, the system comprises intelligent lock control equipment, a pressing plate information intelligent manager, an operation and maintenance handheld intelligent mobile terminal, an operation and maintenance management server and a background system, the intelligent lock control equipment is arranged on a protection screen cabinet of the secondary equipment, and the intelligent lock control equipment is provided with a passive electronic tag; the pressing plate intelligent manager collects, stores, downloads and uploads data information on the passive electronic tag, reads, writes and intelligently manages the information of the passive electronic tag on the pressure plate, downloads an operation task work order and automatically matches an operation object, and guides on-site operation through RFID positioning; the operation and maintenance handheld intelligent mobile terminal interacts with the operation and maintenance management server through a wireless network; the system and method are applied to substations.

Description

technical field [0001] The invention discloses an intelligent operation and maintenance and error prevention control system and method for secondary pressure plates of substations, belonging to the technical field of intelligent operation and maintenance management of secondary pressure plates of substations. Background technique [0002] At present, the on-site operation workflow of the secondary equipment of the smart substation requires the operation and maintenance personnel to hold the printed paper operation ticket, and then operate on the spot sequentially according to the operation tasks and operation steps listed in the ticket. The protective pressure plates of the physical circuit of the secondary system are centrally deployed in the small room. The protective screen cabinets have the same appearance. The status label and the protection name label are affixed under the protective pressure plate in the screen cabinet. The naming of the pressure plates has similar nam...

AI Technical Summary

Problems solved by technology

[0003] 1) The protective screen cabinets with similar intervals have the same appearance, and the label names of the pressure plates in the screen cabinets are similar, so it may be mistaken for entering other intervals or misoperating other pressure plates. The secondary security measures in the operation process management are just a formality

[0004] 2) The traditional manual operation and inspection mode is still used for work such as platen switching operation and regular position check of the platen, and information verification, statistical reports and historical records must be completed manually

The manual checking method is inefficient and prone to omissions, and the timeliness and usability of on-site operation-related data are not strong

[0005] 3) The on-site operation error prevention logic judgment of the secondary protection pressure plate is incomplete, there is no mandatory locking function, and there is a lack of early warning anti-error means in the process. In the event of an error operation in the local operation, it cannot be forced to lock or give an early warning prompt

[0006] To sum up, when the pressure plate of the secondary physical circuit of the smart substation is operated on the spot, because the protective screen cabinet and the pressure plate with similar intervals have similar models and appearances, and the description of the operating objects is similar, it is easy for the operation and maintenance personnel to make misoperations

At the same time, the power safety work regulations clearly require that "relay protection and automatic device pressure plate switching and withdrawing operations must be carried out by two people, and the operation monitoring system must be strictly implemented." However, some operators do not have a strong sense of responsibility. The case of unsupervised operation
