Wireless network-based substation grounding wire intelligent management system

Abstract

The invention discloses a wireless network-based substation grounding wire intelligent management system, which is characterized by comprising a grounding wire fastener and a wireless grounding pile, wherein the grounding wire fastener is arranged in a security tool cabinet, used for fastening a grounding wire and controlled by a grounding wire management host; the grounding wire management host is connected with a fail-safe host; the wireless grounding pile is arranged on site; the grounding wire is connected to a grounding wire end; radio frequency identifier (RFID) chips are arranged on the grounding wire end, the wireless grounding pile and the grounding wire fastener; the connection and disconnection states of the grounding wire end with the wireless grounding pile are fed back to the fail-safe host by a wireless router and a network controller. The system can completely avoid grounding wire misoperation-related accidents, increases the substation grounding wire management level and improves the operation efficiency.

Description

Technical field: [0001] The invention relates to a wireless network-based intelligent management system for substation grounding wires. Background technique: [0002] At present, the microcomputer anti-misoperation locking device in the substation has not effectively managed the use and operation of the temporary grounding wire, and the use and management of the temporary grounding wire are often confused. According to relevant statistics, switching misoperation accidents still occur from time to time, especially the misoperation accidents related to ground wires account for as much as 60% of the switching misoperation accidents in various substations. However, most of the microcomputer anti-misoperation operating systems in the market currently have incomplete grounding locking, and their technical means can no longer meet the needs of anti-misoperation in switching operation and automation of operation management. The state of the substation grounding wire is completely d...

Problems solved by technology

According to relevant statistics, switching misoperation accidents still occur from time to time, especially the misoperation accidents related to ground wires account for as much as 60% of the switching misoperation accidents in various substations. Locking control is implemented in the middle, but the ground wire locking of most microcomputer anti-misoperation operating systems on the market is not perfect, and its technical means can no longer meet the needs of anti-mistake operation and operation management automation.

The state of the substation grounding wire is completely dependent on local manual inspections, and the state of the grounding pile only depends on the return of the computer key and manual comparison. Misoperation accidents frequently occur due to the incompatibility between the grounding pile and the status of the field equipment. The grounding wire installed on the grounding pile on site does not correspond to the primary system diagram, and it is difficult for the operating personnel to find out in time

Especially after the substation is unattended, it is more difficult to find out in time if there is an error in the installation and disassembly of the ground wire of the ground pile. In this case, serious misoperation accidents may be caused, especially before the power is turned on Because the ground wire is only removed from the ground pile, but the ground wire is not completely removed in time, misoperation accidents caused by the ground wire have also occurred many times
