Power quality problems due to short circuit faults, are
defined as changes in voltage, current, or frequency in the power
system. Among the power quality problems in distributed
generation systems are island mode operation, harmonics in
current and voltage, voltage sags/swells, voltage interruptions and
transients. The most common power quality problem in the
distribution system is the voltage sags and swells caused by a short
circuit fault. In this study, various Power quality problems due to
short circuit faults such as line-to-ground, line-to-line and
multistage faults are modeled in MATLAB/Simulink
environment. In order to detect the voltage sag and swell
problems, firstly the voltage sag that occurs in case of failure is
examined and the response of the power system is observed. The
study also models multi-stage failures as a result of failure to
achieve relay synchronization. Examination of the voltage sags
and swells clearly revealed the resulting waveforms, the response
of the power system to the fault condition. Another advantage of
the realized work is that the developed model can be used to
measure the performance of the distributed generation system in
failure diagnosis and classification studies.
