Comparisons of fault calculation procedures are presented in this paper. The primary method considered in this paper is the characteristic currents method. This calculation procedure has been discussed at length in previous work. It is the purpose of this work to present the extension of the previous work to the general case and compare results obtained using this method with results obtained with methods designed to follow recognized ANSI/IEEE and IEC Standards. Complete time-domain simulation is used as the basis for these comparisons. Sample calculations for a system containing multiple induction and synchronous machines are provided for demonstration purposes.
