Model for estimating damages on power systems due to hurricanes

Hurricanes are a threat to power and telecommunication infrastructure. This
work summarizes a method for hurricane characterization using the proposed Localized
Tropical Cyclone Intensity Index(LTCII) as a model for estimating damages
to Electric power infrastructure. The model considers the effect of storm surge,
maximum sustained wind speeds, the duration of time for which the system has
been under tropical storm conditions and the area swept by hurricane over land.
The measurements focus on major load centers in the system. The validation of the
outage data is discussed. The model is evaluated for hurricanes from 2004, 2005
and 2008 hurricane seasons. The degree of influence of various hurricane parameters
on the damages suffered by electric power systems are discussed using case
studies. The maximum outages are observed to follow a logistic regression curve
with respect to log(LTCII), with a correlation of 0.85. The observed restoration
times fit a 6th degree polynomial with an R2 = 0.6. The effects of time under tropical
storm winds were observed to have great significance in the damage profile
observed with the model. / text
