The electromagnetic transients program (EMTP) is a computer program used to simulate and analyze electromagnetic, electromechanical, and control system transients on multiphase electric power systems. This application guide includes examples, procedures, and data to assist engineers experienced in transient analysis using the EMTP code, version 2.0. Aided by user comments on the application guide for the EMTP code, version 1.0, the project team first described the problems encountered in preparing data and applying the results of EMTP studies. They then developed a components guide that describes the structure and limitations of mathematical models available in the EMTP code; that provides guidance to data preparation, including typical parameters for a wide range of equipment; and that contains suggestions about which model to use in various circumstances. The developers then showed how the EMTP code is used to explain situations under which surges can occur and described analysis techniques used to develop sample input files. The application guide provides documentation for modeling transients related to overhead lines, gas-insulated substations, transformers, circuit breakers, surge arresters, initial conditions in a given scenario, and current and voltage sources. The guide includes a study on surges, focusing on those generated during line switching. The work also includes information on transient overvoltages and lightning surges.
