Fractal-based simulations for the assessment of the lightning performance of transmission lines

The overall objective of the research work is the estimation of the lightning performance of HVDC transmission lines following an innovative approach, which combines high voltage engineering with advanced techniques of computational electromagnetics and the validation with recent field data. In the context of this research work a generalized methodology, as well as guidelines, are developed for the accurate computation of the:

  • lightning incidence rate of HVDC overhead transmission lines
  • lightning overvoltages across HVDC transmission line insulators
  • flashover probability of HVDC line insulation due to lightning strikes to transmission lines
