Temporary grounding line management system and control method for distribution network

Abstract

The invention relates to a temporary grounding line management system and a control method for a distribution network. The system comprises a regulation and control center, a handheld intelligent terminal, a smart key and a smart lock, wherein the regulation and control center and the handheld intelligent terminal are wirelessly connected, and the handheld intelligent terminal and the smart key are wirelessly connected; during operation, all grounding line device information is triggered, downloaded and updated on the handheld intelligent terminal; the operation position information is manually input or input by code scanning and sent to the regulation and control center for approval and confirmation; the handheld intelligent terminal compares the grounding wire hung / dismantled state; after a consistent comparison, an authorization unlocking / locking command is issued to the smart key to complete the unlocking / locking operation; after the smart lock is unlocked or locked successfully, alock code value is automatically switched; and the smart key feeds back the switched lock code value to the handheld intelligent terminal to confirm the success of the hanging / dismantling operation and return the success to the regulation and control center to achieve unification of the grounding line information, and to effectively help the operating personnel to quickly understand the situationof the grounding line of the distribution network so as to avoid the occurrence of maloperation.

Description

technical field [0001] The invention relates to the technical field of distribution network temporary grounding wires, in particular to a distribution network temporary grounding wire management system and a control method. Background technique [0002] As a terminal grid for the majority of electricity users, the distribution network has a large workload for on-site inspection and maintenance. However, the existing distribution network automation system lacks the management of temporary grounding wires. The grounding wire information is only managed by manual reporting. There is no Using any technical means, it often happens that the grounding wire information of the distribution network cannot be fed back to the control center in time, and even the on-site grounding wire information is inconsistent with the control center, resulting in misoperation accidents of "closing with grounding wire (power transmission)" and causing serious problems. The safe and stable operation of...
