Abstract

Lightning events can seriously damage the power systems and they represent one of the most dangerous causes of faults in the transmission lines. Usually, when one want to analyze such effects it is necessary to rely on approximate models or to simplify in some ways the power system. As a consequence, an overall analysis taking into account the complexity of the power system is difficult to find. This paper presents the study of the electromagnetic transients caused by lightning events in a point of connection between a real power plant and a large power grid. The analysis is achieved with a high level of details of the power system and the simulations are obtained through an EMT-type software (PSCAD-EMTDC). Different simulations are analyzed, showing how the cables and the transformers are affected by the electromagnetic transients.
