Analysis of lightning transient performance of 132 kV transmission line connected to Miramar wind farm: A case study

Lightning strikes are one of the main causes of power system trip-outs. When the overhead transmission line (TL) connected to a wind farm is struck by lightning, large currents propagate to the substation, resulting in severe problems. To enhance the performance of wind farm substations, the transie...
