Streszczenie
The reliability of power system depends on progress in the coordination of insulation, which depends, among other things, on increasing the ability to identify risks of overvoltage in insulation systems. The purpose of the paper is to present the problems related to the overvoltages in the power system caused by lightning. The article analyses two possible scenarios of sources of these disturbance: shielding failure and back flashover phenomena. The result of the work is the determination of characteristic peak values of lightning current: Imax and Imin – respectively for scenario of shielding failure and back flashover phenomena. Between the Imax and Imin values, we have lightning protection (lightning strikes to ground wire). Calculation were carried out on selected profiles of towers, dedicated to power system with rated voltage of 110 kV, 220 kV and 400 kV (single-circuit and double-circuit three phase line were considered). All simulation cases were performed using The Electromagnetic Transients Program – Alternative Transients Program (EMTP-ATP) and Matlab.
