Lightning current and electromagnetic field modeling

Share

Lightning can produce dangerous effects on power transmission lines. Therefore, reliable models to be inserted into power systems and circuital simulators are of great importance when designing/assessing a transmission or distribution network lightning protection system.

The lecture starts with a brief description of the lightning phenomenon from a physical point of view. Then a detailed analysis of the models available in literature to represent the lightning channel current and the resulting electromagnetic fields is presented. Particular attention is devoted to possible strategies, derived from the solution of inverse problems, for the reconstruction of the lightning channel current starting from electromagnetic fields measurement. Finally, the use of such current and field models as inputs for power system overvoltage analysis is accounted.
