Application of a Simplified Corona Discharge Model to a Lightning Surge Simulation with the PEEC Method
In this paper, a simplified corona discharge model is adopted in a surge simulation with a partial element equivalent circuit (PEEC) method in the time domain. The corona progression from an overhead wire, to which a high voltage impulse is applied, is represented by the radial expansion of the conducting region with a conductivity of 40 mS/m. To confirm the validity of the presented model with the PEEC method, the calculated results are compared with experimental results collected from Noda's experiments. The calculated results agree well with the corresponding experimental ones. This shows that the PEEC method in the time domain with the corona model is of use in simulations of lightning surges propagating along overhead wires.
