Title: A development of a generalized frequency - domain transient program - FTP

A generalized frequency-domain transient program (FTP) is developed in the paper. The FTP is based on a frequency-time transform method adopting nodal analysis, admittance parameter and modal theories. Discontinuous and nonlinear elements are solved as initial condition problems using a piece-wise linear approximation of the nonlinear characteristics. The FTP is used to solve the transient and steady states of a network composed of an arbitrary interconnection of basic circuit elements. The FTP is structured to be compatible with the EMTP so that the same input data and output formats are those of the EMTP can be used. The present version of the FTP can deal with a network with over a hundred of nodes and branches. Comparisons of calculated results by the FTP with field test results and calculated results by the EMTP confirm a high accuracy and a satisfactory efficiency of the FTP. The FTP is of great advantage to offer the most accurate or theoretically exact solutions of transients on distributed-parameter lines.
