| Summary: | 碩士 === 國立中山大學 === 電機工程研究所 === 82 === The power delivery system is generally divided into three
parts: Generation, Transmission and Distribution subsystem.
Distribution system serves as the connection between customers
and the power system. The reliability of the distribution
system has a great influence on the impression and confidence
of customers. Distribution system covers a wide area and
tremendous number of facilities. The system might have 90 ％
faults of the whole power system. How to indentify a permanent
fault quickly and restore the power is an important factor
concerning the service quality of an utility. It is also a
most direct factor for customers to evaluate the reliability of
the system. With the above mentioned characteristics of the
distribution system and the way in handling power interruptions
by the power company, this paper is trying to develop an
efficient way to identify the outage facility of a feeder by
the use of Geographical Information system (CIS). With the
topological capability of the system and the UNIX enviroment
provided by the GIS. The statistics of facility failure rate,
the reliability model and the fault distance can be all used to
find the feeder fault location. In addition, the GIS provides
an user friendly Man-Machine interface which makes the fault
identification processor much easier for dispatchers. It is an
easy and practical way for dispatchers to collect and update
the facility data, to operate with great visibility, and to
process the fault very effectively.
