| Research Abstract |
For analyzing transient voltages induced on installations in and near a wind-turbine-generator tower struck by lightning with the finite-difference time-domain (FDTD) method, several models such as a corona-discharge model and a soil ionization model have been proposed, and their validities have been shown. Then, these models have been incorporated the FDTD-simulation program developed by the author. Mechanisms for generating lightning-induced surges in a lightning-struck tower have been investigated with the FDTD program, and a countermeasure to reduce thelightning- induced-voltage peaks has been proposed.
