Abstract :
Lightning protection studies of substations and
power systems require knowledge of the dynamic behavior of
large grounding grids during electromagnetic transients. This
paper presents strategies which allow to incorporate complex
grounding structures computed using a rigorous electromagnetic
model in transients programs. A novel technique for rational
function representation of frequency-dependent grounding
system impedances in the EMTP is described. An arbitrary
number of feeding points can be modeled as mutual coupling is
taken into account. Overvoltages throughout electrical power
systems and the transient ground potential rise in the
surroundings of grounding structures can be computed.
