After analysis of the fault characters of nonli near resistance network consisting of current-controlled resistors and voltage- controlled resistor s, the fault diagnosis equations of nonlinear resistance network was deriv ed. The unknown quantities of these equations, which are algebraic linear equati ons, are quantities indicating fault of each branch of network . When derivin g the quantities, the variation of electrical parameter caused by v ariation of operating point is eliminated, and the variation caused by variation of v-i cha racteristic is kept, because the later represents the fault occurring in the nonlinear element. In order to solve these fault diagnosis equations with hi gh speed computation on line, we adopted a method based on ANN′s.
