10 KV Overhead Line Fault Detection And Positioning System Research And Application Based On Wireless Sensor Network(WSN)

The rapid development of power system,transmission line distribution is also very complex,very wide spanned geographical,topographical and environmental conditions in these areas are very complex and require high voltage overhead transmission lines in the field of long-term exposure to harsh climatic conditions in these areas,often subject to strong winds,snow,and other effects of natural disasters,but also by the impact of climate change,environmental temperature and humidity as well as temperature changes and other factors lead the staff to maintain and difficult to manage very large line,there are so many negative factors,power transmission line It is extremely prone to failure.Stability and reliability of transmission lines that affect people's life and production of important issues.Firstly,mainly for overhead line transmission system,we analyze the main components in the form of domestic overhead line transmission system for the common short-circuit fault and ground fault theoretically analyzed the types of short-circuit fault and ground fault and short circuit fault and ground fault the characteristics of the line for their own characteristics proposed overhead line short-circuit fault detection and ground fault approach and circuit design to achieve detection.Secondly,in order to better prevent overhead line faults,for hidden faults in the overhead line situation can make warning for overhead lines located outside the main characteristics of the detection means to increase the outdoor meteorological environmental monitoring functions,including overhead line scene temperature,humidity and wind signal acqisition.While increasing the overhead line conductor temperature detection.State of the environment and lead status real-time monitoring for overhead lines each node helps maintain overhead lines.In terms of communication problems,this paper ZIGBEE wireless sensor network as a short-distance data communication,dynamic multi-node inetwork,and sends detection data to the control center through the routing node GPRS module,using GPS satellite positioning and timing information to achieve the time synchronization between nodes and fault data accuracy position information,this paper describes the circuit design and program design of each module,and the completion of the schematic and PCB circuit diagram of design and production.This paper also gives a brief experimental device designed to analyze to verify the feasibility of the current detection circuit,and collect multiple sets of data were analyzed and compared,test the correctness of function meteorological sensors and wire temperature sensor function.Finally,this paper the next direction of development and prospects.
