Along with the increase of need for high reliability of the power system security, it is important to build up a distribution fault analysis network and processing system, which can provide decision-making help for dispatching personnel. This paper introduced framework of the distribution network fault analysis and processing system, and analyze the fault location, isolation, generation and evaluation of power supply reconfiguration strategy. Tree model and Heuristic search were used for fault location and power supply route switching strategy.

An Application of Heuristic-Search Based Tree Model in Fault Analysis of Distribution Network

Whenever a fault occurs in a particular section of a distribution network and on isolation of the fault, some of the loads get disconnected and are left unsupplied. Service should be restored to these affected load points as quickly as possible through a network reconfiguration procedure. A new and efficient technique is presented in this paper for this purpose. Network reduction and determination of the interested trees of the reduced network by a specially developed algorithm for finding the required restorative procedures, are the main contributions of this paper. >
