“…Lightning transient behavior of the wind turbine electrical devices depends on the characteristics of the lightning current waveform and the configuration of the grounding system. Most of the failures have occurred on low voltage electrical circuits inside the wind turbine [1]. Such damages are possible coming from the overvoltage rise on the grounding system due to the direct lightning strike, induced overvoltage on the cable lines, and lightning surges coming from the nearby lightning-stricken turbines [2,3].…”

This paper aims to compute the lightning electromagnetic transient overvoltage and current on the wind turbine using the PSCAD/EMTDC simulation program. The double-peaked lightning current, tower, grounding system models, and dangerous situation of the grounding system are investigated by the PSCAD simple circuit branch segment codes and defining components. A comparison analysis has been performed to see the influence of lightning current wave shapes and grounding characteristics. The simulation results show that 43 kA and 31 kA lightning currents produce 200 kV overvoltage on the turbine grounding in case of 1000 Ω·m soil resistivity. However, current amplitudes on the equipotential grounding system become 28 kA and 20 kA. The influencing factors of the surge protection device are determined using good accuracy computer simulation.
