methods in which vehicle performance is not adjusted in real time.
In those models, train voltage and
performance are calculated in
a separate module that does not
feed back into the electric network,
resulting in inaccurate train loadings and locations.
Technology applications: The
applications for dynamic modeling
include assessing traction power
and operational system limitations; prioritizing traction power
improvements to coordinate with
the commissioning schedule of
new vehicles or increase in service
and capacity; evaluating the feasibility of new operational schedules;
evaluating wayside and onboard
energy storage systems; and identifying construction sequences to
minimize disruption to service.
The results from the studies provide the framework for the design

LTK Engineering

of the traction power system.
For models that require further correlation to actual performance, onboard collection of
data provides direct vehicle power analyses. Information such as
train voltage, current, and GPS
location are collected using data
acquisition hardware, transducers, and GPS sensors, allowing
engineers to pinpoint locations
where power system anomalies

occur and to correlate the model with actual daily operations.
The combination of load flow
modeling and data acquisition
can reveal system performance
characteristics with greater precision, allowing transit systems
and railroad operators to make
better-informed decisions and
apply resources where they will
have the greatest positive effect on
the operation.
