In this paper, an effective method is presented to determine
the substation siting and feeder planning based on the
shortest path. A geographic information system (GIS)
with distribution database, state-of-the-art computer graphics
and a proposed method are integrated to solve the
sizing and siting problems of distribution substations, and
to perform feeder routing, including load transfer to the
neighbouring substations. A GIS provides an environment
for building a database which contains both graphic information
and non-graphic facility data. A distribution system
of the Taiwan Power Company (Taipower) in Kaohsiung
ci O, was selected for the test. It can be shown that the
proposed process will pro vide a physical en vironmen t and a
friendly man-machine ir,:terface (MMI) for planners to
perform the distribution planning.
