| Summary: | Lightning has been a major concern to the power
system researchers because it can cause damage to the
connected electrical equipment and transmission failure.
One study carried out is that where the level of voltage at a
substation is observed following a backflashover analysis
on a transmission line. Sample of worst case transmission
line was taken from Tenaga Nasional Berhad, which is 132
kV Kuala Krai-Gua Musang line for the purpose of
simulation using PSCAD software. An integral part of this
study is the model of transmission line components such as
insulator coordination gap flashover, tower model,
nonlinear current dependent resistance as footing model.
All models are verified by accurate analysis of previous
researchers. Results were analyzed and influences of line
parameters to bakflashover rate were discussed. Practical
recommendations and conclusions based on the results are
made for an improvement in the lightning performance of
high voltage transmission line. |
