Study Of Fault Location And Network Reconfiguration In Distribution System

With the continuous scale-up of Distribution Network,Automation technology of Distribution Network become more and more important . Based on the network existing ,we can change the structure to gain more economic benefits and to gain better quality of electricity . More and more people focus on this yield. It become the central issue of the research of Distribution Network . Network Reconfiguration is the solution of this problem.A online detection system is constructed in this item .The system can display the network dynamically,take data of line and data from testing equipment into charge,remove permanent fault quickly and opportunely, do Network Reconfiguration under condition of least impact to power grid.The goal of this article is Network Reconfiguration, and divide it into two parts: restoration of Network Reconfiguration and majorization of Network Reconfiguratio- n.Based on the feature of Distribution Network ,the mearsurements we take are rule to main objectives and rue of picking. Through these , we can get the model of Distribution Network .Under these , we anlysis some pop algorithms carefully and compare them. We use marix algorithm to locate fast fault. At last , Ant Colony Algorithm is our best choose to change the configuration of Distribution Network from closed loop to open loop. Also, the flow calculation is very important . We think forward and backward substitution method is the best to our network. Because it is easy to read and revise. During the judgement of the network, every possibility is under consideration to prevent omission some answers .So we can get solution of overall situation .The tool we use to program out these solutions are VC++ and MATLAB. The example we choose to prove our algorithm third-division-and-three-consecute network.
