Fault section estimation in power system using Boltzmann machine

The fault section estimation problem can be formulated as a nonlinear integer optimization problem. The Boltzmann machine is applied to solve the problem. Since the objective function for the problem has the form of high order polynomial expression, an approximation is made so that the Boltzmann machine can be easily used for the problem. Another problem is to find out all solutions that have equal probability. The objective function is modified for solving the problem. As a result, for single and double fault cases, the Boltzmann machine with modified objective function works very well.
