Transmission Lines Ice Research And Implementation Of Online Monitoring System

The transmission line ice-line monitoring system come from computer technology,micro-signal sensing technology, electromagnetic compatibility technology, dataprocessing technology, image compression technology, low-power technology, networkcommunications technology as one of the high-tech products, the online operation ofthe transmission line status related to the efficiency and security of grid operation. ICEDline monitoring of the transmission line integrated monitoring of meteorologicalconditions (temperature, humidity, wind speed, wind direction, barometric pressure), thevideo picture Icing appearance and generate the observed, the use of research results athome and abroad to cover the ice load calculation, ice growth mechanism, conductorgalloping, towers and gold with the theoretical study of the strength check, and with theexisting Unicom/mobile mature communications network for real-time datatransmission, combined with expert knowledge base and a variety of modified theorymodel, the forecast of ice conditions in a timely manner given the de-icing information,and effectively prevent ice damage accident. Patrol officer is not easy to reach theregion, greatly reducing the number of inspections, inspection and condition basedmaintenance of transmission lines has opened a new method: the system in achieving onthe basis of quantitative measurement of the line ice, and then carry out a qualitativeanalysis of the line ice The combination of greatly improving the accuracy of the icecover measurement and prediction, effectively preventing ice damage accident hazardsgrid operation security.This paper describes the current situation and problems to be solved of the onlinemonitoring of overhead transmission line monitoring system technology and reliabilityanalysis of the line ice-line monitoring of specific approaches and solutions. IcedTransmission Line Monitoring System platform set up the overall function of thefollowing: system management module, the scalability of the system framework,multi-level hierarchical permissions to control lines and data manipulation system.Lines, monitoring equipment and other modules, the establishment of a unified databased stations, monitoring units and other equipment, detailed set different parameters of the design, operation, and unified management and maintenanceof the infrastructureof the transmission line. It trend curve monitoring data display, query, statistics andother functions. Through a statistical analysis module, on-line monitoring data, alarmdata, the statistical analysis the fault information and to view the operational status ofthe monitoring equipment to provide statistical analysis of the transmission line, alarm,fault and other information statements, reports, grid operation unit. The alarmmanagement module, tips, early warning, and alarm information to classify. Theplatform highlights the line of operating personnel decision support capabilities to helpsolve practical problems in the line. The failure of the transmission-related departments,and the incident handling process, improve efficiency and speed of processing by therelevant departments to emergencies.
