Abstract

This paper deals with analyzing specific transient states of voltages in electric power systems of high voltages. The paper presents the results of the analysis of operational disturbances caused by lightning discharges in 110 kV power system. Furthermore, the analysis results of lightning surges as well as the optimization results of a surge protection system installed in a 110 kV substation are presented. A model of an electric power system (overhead lines and substation) and all simulations were performed using computer software Electromagnetic Transients Program-Alternative Transients Program (EMTP-ATP). This model is based on a set of appropriately connected elements (distributed and lumped parameter elements) taking wave effects and nonlinear effects into consideration.
