1. A neural load disturbance analyzer for classifying a utility, power load disturbance into one of a plurality of disturbance modes, the neural load disturbance analyzer comprising:
- a pre-processor which samples a signal indicative of a utility, power load at a plurality of times, the pre-processor generating pattern data representative of a pattern indicative of the samples;
a trained neural network disposed to receive the pattern and determine a winning output representative of the utility, power load disturbance;
a post-processor disposed to monitor the winning output and select a disturbance mode representative of the utility, power load disturbance based on the winning output; and
means for determining the probability of a utility, power load disturbance based on the number of occurrences of the winning output in the pattern data during a predetermined period relative to the total number of patterns presented to the neural network during the predetermined period.

Abstract
A system and method for controlling the generation and distribution of power is disclosed. The system includes monitoring devices which acquire load data indicative of the system load. The load data are converted into patterns which are fed into a neural load analyzer configured to classify the patterns. The generators of the power system are controlled responsive to the resulting classifications.

5. A method of training a self-organizing neural network having connections with weights and biases to distinguish between patterns representative of utility, power load disturbances, the method comprising the steps of:
-
retrieving data indicative of utility, power load disturbances at a plurality of times; generating a set of pattern data groups representative of the utility, power load disturbances; successively applying each pattern data group to an input slab of the self-organizing neural network, determining winning outputs based on the pattern data group and the weights and biases of the connections of the self-organizing neural network, and adjusting the weights and biases of the connections to segregate the utility, power load and determine responsive actions; determining the number of times the winning output of a pattern wins during a training epoch; and determining the probability of the occurrence of a disturbance corresponding to the winning output of the pattern by dividing the number of times the output wins during a training epoch by the number of pattern data groups. - View Dependent Claims (6, 7)
