Substation ground wire monitoring system and method

Abstract

The invention provides a substation ground wire monitoring system and method which aims at avoiding the wrong operation which is easy to cause when devices of a hanging ground wire and the like are detached in a substation, reducing the number of the wrong operation of the substation, improving the safety coefficient of the power production and protecting the personal and equipment safety. The substation ground wire monitoring system comprises a radio frequency scanning receiver, a radio frequency card and a ground wire control unit which is arranged in a ground wire chamber; the radio frequency scanning receiver is arranged in a ground wire cabinet; the distance between the placement position of the radio frequency scanning receiver and the placement position of a ground wire head is within an effective receiving range; the radio frequency card is placed on the ground wire head; the ground wire control unit is formed by an embedded computer and a plurality of 485 communication ports, wherein the embedded computer serves as a center controller and the ground wire control unit is connected with the radio frequency scanning receiver through the radio frequency scanning receiver; the ground wire control unit is connected with a background computer of a main control room in a wireless communication mode and connected with a voice alarm system and a liquid crystal touch display screen of the main control room through the background computer.

Description

technical field [0001] The invention relates to a substation ground wire monitoring system and a monitoring method. Background technique [0002] According to the latest statistics of the State Grid Corporation of China, the vicious accident of closing with a grounding wire (grounding knife switch) accounts for the first place in various misoperation accidents. The vast majority of them are caused by missing temporary grounding wires after equipment maintenance, which mainly reflects problems such as imperfect organization and management measures or lax implementation of temporary grounding wires. In the past, the monitoring of the ground wire was collected by mechanical contact contacts. After a long time, poor contact of the contacts and inaccurate status would occur. Contents of the invention [0003] In order to avoid misoperations that easily occur in substations when disassembling and attaching grounding wires and other equipment, reduce the number of substation mis...
