| Abstract |
The power quality problems of DC electrified urban
railway systems are discussed for the unit commitment situations
on the main transformers of the traction substations. Utilizing
unit commitment and the transformer planning procedure for an
electrified traction system which is applied to derive the optimal
transformer capacity to meet the annual peak demand and
provide reserve for service reliability, minimizes the overall cost
of main transformers over the life cycle. On the other hand, some
power quality problems are caused or even emphasized due to
the natural characteristics of the traction system. The dynamic
programming method of unit commitment is done in MATLAB
where its results are the input data for the rest of our power
quality investigation procedure. The power quality
characteristics of the traction system are then studied and
verified through the simulation results done with
PSCAD/EMTDC software. |
