Abstract


Distribution Automation is the current focus of urban and rural power grids work . With China's sustained socio-economic development , electricity supply reliability users have become increasingly demanding , the promotion of distribution automation system is imperative . The distribution network fault location and the loss of power distribution automation regional recovery is the core issue . Distribution network fault section location and power restoration reconstruction algorithm and its improvement is the focus of this thesis research . This paper briefly introduces the concept of distribution automation and distribution network topology model and the distribution network fault location and recovery of the status quo. Then introduced the distribution network fault section locating and restoring some of the existing algorithms . Existing algorithms for some shortcomings , this paper proposes an approach based on improved ant colony algorithm of distribution network fault location and recovery algorithms. Ant Colony Algorithm in Distribution Network Fault section targeting achieved a better effect , but the algorithm searches for a long time , such as lack of slow calculation , this paper has been improved ant colony algorithm is constructed with dynamic adaptation grid topology switching function is proposed ant pheromones initial setting method , introducing solutions disturbance rules that determine the ant colony algorithm is applied to multiple power distribution network under fault section positioning methods . In the distribution network fault recovery in this paper, based on graph theory powered fast recovery algorithm and intelligent global optimization algorithm can arrive at the advantages of ant colony algorithm is proposed based on reconstruction and the need to dynamically determine the node switch set power is restored improved algorithm, and considering that the algorithm needs to load shedding , multiple faults case approach.
