Method for evaluating the faulted sections and states in a power transmission line
First Claim
1. A method for evaluating a faulted section in power transmission line by measuring the current flowing through an aerial earth wire at a plurality of places along the power transmission line to evaluate the fault section from the measured information, comprising the steps of calculating the measuring information resulted from the faults in various positions by the previous fault simulative calculation;
- introducing the resulting fault simulative measuring information into a self-organizing neural network having output elements of which number being more than that of input elements to permit the self-organizing neural network to learn the classification of the simulative measuring information;
preparing an evaluation rule representing the correspondent relation between the output from the classification of the simulative measuring information and the faulted position;
thereafter introducing actual measured information into the self-organized neural network to permit the self-organizing neural network to classify the introduced actual measured information and evaluating the faulted section from an output classified by the self-organizing neural network on the basis of the evaluation rule.

Abstract
The faulted sections are evaluated by calculating the measuring information resulted from the faults in various positions by the previous fault simulative calculation, introducing the resulting fault simulative measuring information into a self-organizing neural network having output elements of which number being more than that of input elements to permit the self-organizing neural network to learn the classification of the simulative measuring information, preparing an evaluation rule representing the correspondent relation between the output from the classification of the stimulative measuring information and the faulted position, thereafter introducing actual measured information into the self-organizing neural network to permit the self-organizing neural network to classify the introduced actual measured information, and evaluating the faulted section from an output classified by the self-organized neural network on the basis of the evaluation rule.
