Abstract
Abstract:
Resolving imbalances on phases is performed using
conventional trial and error approach which involves service
interruption. Phase current and voltage may improve however
the resultant effect does not last for too long. To improve the
performance of the secondary distribution system there is a need
for an on-line and automating technology. The aim of this paper
is to pioneer a method and technology for resolving imbalances in
a secondary distribution system as a result of the uneven
distribution of single phase load across a three phase power
system. The technology developed involves monitoring,
acquisition/display of collected data and self changing switching
actions electronically for rearrangement or transfer of consumer
loads. The proposed switching technology is based on opentransition
switch that enables transfer or rearrangement of
consumer loads in a three-phase system within milliseconds with
supervisory control system. Validation of the proposed
technology was carried out using these methodologies: Matlab
(Simulink), Virtual Instrumentation-Lab VIEW and Hardware
implementation.
