Sumario:This work presents an overview of a methodology based on the Numerical Laplace Transform (NLT) and applied to the analysis of electromagnetic transient phenomena in power systems. The basic development of the method is described, with its main qualitative advantages as compared to conventional time domain methods, such as the method of characteristics and professional programs for transient simulation such as EMTDC and ATP/EMTP. Current practices for reducing errors derived from the truncation and discretization of the analytical equations are also discussed. Finally, some important results obtained recently with this tool are shown. Comparisons with time domain methods reveal a high accuracy of the Numerical Laplace Transform in several studies.
