| Outline of Final Research Achievements |
For analyzing transient voltages generated in an electric power facility such as a photovoltaic power generation system struck by lightning with the finite-difference time-domain (FDTD) method, several models such as a corona-discharge model, an arbitrary-radius thin-wire model, and a high-performance absorbing boundary condition have been proposed, and their validities have been shown. Then, these models have been incorporated in the FDTD-simulation program developed by the author. Mechanisms on how overvoltages are generated have been studied with the FDTD program, and a countermeasure to reduce the lightning-caused overvoltage peaks has been proposed.
