Study of Lightning Intruding Surge for 330kVGIS Substation Based on EMTP/ATP
This paper combines incoming lines with 330kv GIS substation, considering the impulse corona of incoming lines, the impulse grounding resistance of tower and the position of lightning. EMTP/ATP simulation program is applied to analyze the lightning intruding surge of 330kv GIS substation. The result shows that impulse corona and the resistance of tower which is close to the substation have great influence on intruding surge, when lightning strike the tower which is close to terminal door-typed structure, the lightning intruding surge may be not the most serious, and when the intruding surge of the equipment is very serious, a group of arrester is installed which can decrease the intruding surge effectively. This study thinking takes safety and economy into account, which can provide new reference for the engineering.
