Research On Switching Optimization And Fault Location Of Distribution Networks

Optimal switching device, fault location and isolation and FTU devices' research and design based on method for fault location are important aspects of distribution network automation and distribution network optimization. Configure switching devices in electric distribution networks according to structure of networks and based on switching optimization, research on fault location and isolation.The paper analyses optimal switching devices in the distribution networks, sets up a model to decide to judge types and numbers of switchs in proper location of distribution networks and applies to partical swarm optimization to compute. The simulation system is constituted with matlab. The paper discusses and analyses theory of fault location ,excogitates a synthesis matrix algorithm and an algorithm based on GPRS for fault location and isolation.
