Hybrid fault location algorithms for distribution systems –
The algorithms are based on both: a) the model of the system, and b) the
knowledge extracted from the measurements, and from the protective devices.
This approach overcomes the traditional fault section estimation methods,
solving the multiple estimation problem based in measurements at the
substation.
Sags characterization and classification -
Feature extraction from voltage sags registered in a distribution substation to
achieve the diagnosis task. These features will be used as inputs of a
classification algorithm; to obtain classes which are related to the power
system response under fault situation. The obtained classes will be related to
classical algorithmic methods for fault location. The goal is to associate the
voltage sag registers with the location of its cause.
Restoration strategies on transmission substations:
This research is aimed to improve the power service indexes by means of speed
up the utility response to fault conditions. As a result of this project the
under-fault procedures and contingency guides were developed. Under-fault
procedures are oriented to help utility operators and technicians to restore
the service under conditions of non-destructive faults. Contingency plans are
oriented to be a practical guide under conditions of destructive faults in
breakers and transformers.
