the major problems that faces the repair of electric utility facilities is
the amount of time it takes to make repairs. If the repair time follows closely
after an earthquake main shock, potential exists to endanger repair crews
working at a site from after shocks.
An opportunity exists to be able to optimize the kind of repairs that
are being performed after an earthquake to reduce the risk of failure from aftershocks.
structure interaction offers a significant opportunity for optimization of
the repair process. Liquefaction
and landslide potential are not currently being evaluated for potential
seismic safety concerns of crews doing repairs after an earthquake.
management often means developing a priority for a limited number of
resources to make the power system as safe as possible in a short amount of
time while restoring service to essential or critical customers first. Many circuits that have downed wire
after an earthquake represent a threat to the population because the wire is
now on the ground. If that
circuit does not provide power to any essential or critical customers for
emergency response, then those wires can be cut and cleared away to allow for
repair at a later date.
Opportunities exist from damage assessment information in emergency
management software to identify these potential seismic safety tasks and
optimize the use of available crews.
