초록

Photovoltaic Power Plant(PV plant) facilities are attracting the most attention among new and renewable energy power plants, and they have been steadily are growing not only in Korea but also in the world. As the demand for PV Plant installation is continuously increasing, damages to the PV Plant are also increasing due to the lightning induced overvoltage caused by the lightning stroke. In this paper, the maximum lightning induction overvoltages at the critical facility for the Large-Scale PV Plant, (such as transformer, inverter, connection panel and distribution panel) in lightning strikes are compared by grounding systems (Isolation Grounding/Common Grounding) and composition of critical facilities (one critical facility, two critical facility) with simulation utilizing CDEGS.
