| Abstract: | Through the combination of recursive formulas of Volterra Series and Block-Pulse Function Tranform (BPFT), a new method of hybrid model identification was proposed for a class of nonlinear dynamic networks, and the corresponding expressions and the solution methods for dynamic responses were derived. Based upon this hybrid model, the fault location method for nonlinear networks was proposed by using multipreset models. This method could avoid the current model of the on-line computer system. Therefore, it is easy to realize on-line fault location. |
