Using Electromagnetic Transient Program (EMTP) for accurate prediction of faults location

Electrical power systems are sophisticated networked grids, which need to function with high reliability to provide electricity to customers. With high number of interconnected busses and devices in both transmission and distribution networks, electrical power systems need powerful programs to perform high speed calculations. This paper describes the Electromagnetic Transient Program - Alternative Transient Program (EMTP-ATP) and its usage in modeling of faults behavior in complex electric power systems. The results from EMTP-ATP modeling were compared to models in PSCAD to validate developed models. EMTP-ATP is further used in this paper to show steps in designing a system with a Single-Line-Ground fault (SLG) to analyze high frequency composition of SLG faults.
