Passive Ad Hoc Network Transmission Line Real-time Monitoring Technology Research And Application

Transmission line is an important part of power system,anditis the basis for the safeoperation of power grid. Due to transmission line dispersion, line coverage, geographical andclimatic conditions and other factors constraints,the transmission line has been lack ofsufficient safety precautions, the construction of power grid andmaintenance of equipment arebecoming more and more. The traditional detection methods for transmission line areaffectedby subjective factors easily, and so it is difficult to ensure resultsaccurately. It is unable torealize that the real-time monitoring information transmits to the monitoring center oftransmission line, which cannot detect the hidden danger of transmission linetimely, leadingto the occurrence of safety accidents, affecting the safe operation of power grid.In order to improving the safeoperation level of transmission lines, enhance thereliabilityofpower system operation, strengthening the operationmanagementmonitoredthetransmission line distanced andall-round, masteringoperation of theline, reducing operation and maintenance costs, improving economicand social benefit ofenterprise. Therefore, it is urgent to establish a real-time monitoring transmission linesystemwhich has rich functions and reliable performance. On the basis of the reference that havegreat achievements in literature and research, combining withthe present monitoringstatus oftransmission line, according to the analysis ofkey technology on wireless sensornetwork,thestabilityand operating conditionsof transmission line real-time monitoringtechnology, proposeadesignof transmission linereal-time monitoring platform which based onpassive ad hoc network, and then use the design to establisha transmission line real-timemonitoring platform.The transmission linethat is based on the passive ad hoc networkproposed in this paperhas been running well since operating, meeting the basic requirements of safe, reliable, stableoperation, which has been fully applied in high voltage line real-time monitoring management,improvingsupervision and management level of the line, realizedthe whole processsupervision and management ofthe whole test line.
