The Study Of Transmission Line Security Monitoring System

The transmission line is electrical power system's artery, once has the accident, it will create the heavy economic loss and the social impact. Therefore, the transmission line safe steady operation is very important. Our country starts to carry on the intelligent electrical network construction from 2009; one of its important contents is carries on the safe monitoring to the transmission line.In the topic the transmission line safe monitoring uses the video frequency real-time monitoring, when appears exceptionally, can the prompt accurate gathering scene information, undergo the analysis and processing, uploads to the distant place control terminal, enables the staff the stitch in time, reduced greatly artificial patrolled the number of times and the work load. In the article introduced the video frequency monitoring uses the solar cell main return route's constant voltage design and so on, simultaneously in detail introduced in several kind of monitoring the commonly used sensor and their principle of work.The paper also emphasis studied the transmission line overhaul to meet the grounding safe supervisory system, has realized the docking grounding safe monitoring from the technological means that its main achievement was as follows:(1) The paper proposes one kind brand-new take electric power GIS as the foundation platform, realizes using the GPS localization and the two-way charges for cellular phones technology meets the grounding safe monitoring the technical program, and develops the practical system.(2) The paper succeeds develops a sleeve joint grounding signal unit/launching apparatus, establishes, in meets the grounding to hang supposes in the handle, uses in transmitting meets the grounding to hang supposes the status messages and hangs supposes the space position information;(3) The paper succeeds develops a sleeve joint grounding computer management system. Uses in judging and the demonstration meets the grounding to hang supposes the status messages and hangs supposes the positional information:Through the electric power GIS data which gathers has carried on compared to rightly with the database, uses the GIS formidable spatial analysis function, judges automatically every one pays meets the grounding to hang specifically supposes the line and the poles and towers number, every one pays information and so on grounding what time contact.This article studies the transmission line safe supervisory system has the important meaning to the electrical power system safe steady operation.
