Abstract

A computer algorithm for the harmonic analysis on steady state of single phase power systems containing a transformer saturation model is presented in this paper. The model proposed has been developed on a finite difference numerical method. The algorithm illustrates the application of the model. The numerical results have been validated with PSpice and EMTP/ATP simulation programs. The method proposed exploits the double-diagonal structure of the matrix, and a fast resolution algorithm is obtained
