This document presents the Ratan Das
method. This method allows the location
of faults in distribution systems with
branches. The method employs the
computation of apparent impedance at the
moment a fault occurs. It considers prefault
voltages and currents phasor of nodes
that are down and up the fault. These data
are employed as input for the method and
they are being processed to gather a nonlinear
equation. This equation could be
employed to compute the distance that a
fault occurred. When the fault occurred
on laterals, they could get several
distances. One of these distances is
chosen as the closest to the correct one.
These distances are calculated by an
iterative process. This process includes a
random component in order to decrease
the calculated error.
The proposed model is tested in
distribution networks. This type of
network is well known for its nonhomogeneity
on distribution lines. It also
has changes on connected load and the
existence of laterals. Those aspects have
changed the traditional way fault location
problem is solved. The way is different
comparing to the solution for transmission
lines.
One of the objectives to achieve is prove
how accurate this method is to locate
faults. A fault locator is important for
distribution companies and helps to
improve reliability of distributions
networks. The comparison is made
between the calculations and the data gathered in a simulation software for
distribution systems. |
