This thesis is to develop the power line carrier based
identifier for the determination of customers served by each
distribution transformer. The signal transmission characteristics
of the power line carrier (PLC) over low voltage distribution
lines and investigated. By executing the connectivity validation
with the identifier developed, the accuracy of outage
management system database can be enhanced for different
types of customers (commercial /office buildings, commercial/
buildings, residential buildings) Various application functions
such as contingency maintenance, transformer load
management and customer outage management can be
supported by outage management system (OMS) system more
effecting.
The mathematical models of 1£r2W, 1£r3W, 3£r3W and
3£r4W distribution have been developed by including the high
frequency equivalent circuits of transformers, low voltage lines
and customer loads in the computer simulation. The systems of
signal coupling circuit, data processing, man machine interface
have been designed with the embedded firmware for the PLC
identifier.
To demonstrate the effectiveness of the PLC identifier, a
field test has been performed in Tainan District of Taipower. It
is found that the customers served by each distribution
transformer can be determined correctly with the PLC identifier
developed.
