Abstract
This paper analyzes the lightning protection of a 110~kV substation in a wind park, focusing on transients caused by lightning strikes to the connected 110~kV overhead line. Two configurations of surge arresters are compared: 1) application of the standard surge arresters installed in the line bay between the grounding system and phase conductors, 2) application of the surge arresters at the gantry tower. Both solutions are compared from the aspect of maximum amplitudes of lightning transients in the substation, as well as from the aspect of the energy stress of two sets of surge arresters at the 110 kV voltage level. Regarding the maximum amplitudes of lightning transients in the substation, it is presented that in the analyzed case, both solutions have some advantages and disadvantages, and neither solution is better in all aspects. However, standard installation of surge arresters in the line bay is significantly efficient from the aspect of sharing energy stress between the sets of surge arresters.
