Information Fusion Based Fault Location Technology for Distribution Network
Along with the increasing the level of distribution network intelligence and the network complexity, the automatic fault location technology for distribution network is particularly important. But the traditional fault location methods based on one information source is impossible to locate the faults accurately because of there are losses or faults in the information from the distribution. So, the information fusion based fault location method for distribution network is proposed. When a fault occurs, one information matrix is created based on the action of all the protective relays, and the other information matrix is created based on the wave data of the current which is recorded at the foot node.
