Research And Application Of Intelligent Anti Theft And Real-time Location System For Power Cable

Electric power line is the lifeblood of power grid operation.It in electric power transmission is vulnerable,any damage from outside and staff mistake operation,is likely to cause blackouts,even to grid collapse.It brings great harm to the social economy and people's life.Therefore,the study on power line online detection and diagnosis method,has very important meaning.The system is actually meaningful fot the network of power system for that it is the power line that make the net node come to be linked.The study on online detection and diagnosis for the transmission lines is more at home and abroad,and focus on line after fault diagnosis and orientation,belongs to the off-line fault diagnosis.However,less research on distribution circuit.The existing monitoring device and positioning device can't dor the operation of the distribution circuit achieves real-time monitoring and the transient fault lines,and is not obvious characteristics of the high impedance fault effective detection and diagnosis.If the fault early of distribution line is not ruled out in time,it is likely to become a short circuit fault,which has the possibility to cause harm to the safe operation of power system.Because the cable is not affected by natural conditions,and the volume is small that do not take a line corridors space,et.The cable plays a more and more important role in the power supply,with the development of power grid and expand.But it is difficult to find the failure.As result,it's obvious that it has important engineering significance to ensure running safety,rapid diagnosis and cable repair fault.The technique of power cable offline fault location has been basic mature,but the technology of power cable online fault location is not yet mature.This topic put forward a scheme of a set of distribution line on online monitoring,the diagnosis and forecasting system,and devices the monitoring and run the test.This paper mainly involves intelligent anti-theft system for sheathed power cable is a kind of new intelligent security systems,to fill the gaps in the field.This product is using the latest network monitoring technology,the high frequency signal detection technology development such as openness,networking and the brand-new idea of modularization,digital power cable intelligent anti-theft system and industrial and mining enterprises ideal transmission line anti-theft products.The system is the powerful guarantee of the safe operation of the power grid.This system is a powerful guarantee of the safe operation of power grid.
