| Summary: | This work is aimed at developing electromagnetic
modeling techniques to enable researchers to predict the
behaviors of substation grounding system to lightning strikes
using a 1-D transmission-line model. Several simulations have
been done using 1-D TLM algorithm with two different injection
impulses for comparison purpose. The method has been validated
by contrasting with an algorithm based on a distributed model of
an electrode where a good agreement was found. And, it is
important for the selection of allowable one segment length of the
1-D transmission-line model to be less than 20% of its total length
to produce reliable and accurate results of the transient
responses. |
