| Notes | distribution network; feeder automation; fault location; description matrix; fault judge matrix; matrix algorithm An improved general matrix algorithm is presented to locate faults in complex distribution networks with multiple source and multiple faults. Firstly, the paper supposes the only power source and the positive direction according to the system＇s structural characteristics, and establishes the description matrix D which is based on the positive direction and the relevancy between different feeders. Secondly, we install three working modes in the feeder terminal units （FTU）, including positive over-current, reverse over-flow and normal model, transform the diagonal elements of the matrix D based on the direction sent from the feeder terminal units（FTU） to set up the fault judgment matrix P. Finally, we locate the fault section using the criterion. This method needs not matrix multiply or standardization. It＇s easy to build the description matrix D, which is very sparse and has small amount of calculat |
