Secondary maintenance safety measure ticket system and realization method thereof

Abstract

The invention relates to a secondary maintenance safety measure ticket system and a realization method thereof, and relates to the technical field of secondary maintenance safety measures in the direction of intelligent transformer substation secondary operation. The secondary maintenance safety measure ticket system comprises a model data management module, a real-time database, a historical database, a graph editor and an safety measure ticket application module. The realization method of the secondary maintenance safety measure tickets realizes a series of function requirements of secondary maintenance safety measures, such as intelligent ticket simulation, anti-error verification, rehearsal simulation, safety measure ticket management and visual display. The secondary maintenance safety measure ticket system and the realization method thereof solve the problems that conventional manual programmed secondary safety measure tickets are high in difficulty and error-prone and system management is unavailable for the secondary safety measure tickets, the working efficiency of secondary maintenance personnel is improved, the validity and the accuracy of secondary maintenance safety isolation measures are ensured, and the safe and reliable secondary maintenance safety measure implementing technology guarantee and an application system support system are provided for operation, maintenance and reorganization and expansion work of the intelligent transformer substation.

Description

technical field [0001] The invention relates to the technical field of secondary operation and maintenance of intelligent substations, in particular to a security ticket system for secondary maintenance and an implementation method thereof. Background technique [0002] With the large-scale promotion of smart substations, the problems of early design, equipment and application of smart substations are gradually exposed. The secondary system has added merging units, intelligent terminals and a large number of switches, making the secondary system more complex; using optical cables instead of cable connections, the entire secondary system is based on SCD files, and the secondary loop (virtual terminal, virtual loop) has become a "black box". "; At this stage, the secondary system products do not effectively solve the maintainability problem of the secondary system of the smart substation, the management is extremely complicated, and the safety risk is high. [0003] In order ...

AI Technical Summary

Problems solved by technology

The secondary system has added merging units, intelligent terminals and a large number of switches, making the secondary system more complex; using optical cables instead of cable connections, the entire secondary system is based on SCD files, and the secondary loop (virtual terminal, virtual loop) has become a "black box". "; At this stage, the secondary system products do not effectively solve the maintainability problem of the secondary system of the smart substation, the management is extremely complicated, and the safety risk is great

[0004] Although the State Grid Corporation of China has done a lot of normative work on the safety measures for the second maintenance, the current safety measures for the second maintenance still lack a lot of technical and system support, especially the work of invoicing the safety measures for the second maintenance basically stays in relying on experience and searching a large number of Under the premise of relevant design data, the manual template billing mode is performed, the work efficiency is low and mistakes are prone to cause safety hazards and accidents
