Summary: | 碩士 === 國立成功大學 === 電機工程研究所 === 82 === This thesis proposes a distribution automation case study
for National Cheng Kung University (NCKU). Supporting from
possible re-installation plan in NCKU, an effective and
reasonable method to restore the non-faulted out-of-service
area is proposed. The proposed method in this thesis is
combined with a fully automated distribution system. In the
control center, distribution engineers can recieve the
information of the distribution system. When a fault has
been detected, distribution engineers can isolate the
faulted zone, restore the non-faulted out-of-service area
through the control of switches and tie-switches in the
automated distribution system. Using load flow calculation
method to analyze and modify various loading case of the
possible outage area, therefore the solution can determine
the priority of the tie-switch for each outage case and
establish a restoration data base. At the instant of fault,a
suitable solution is directly searched from this data base
to restore the out-of-service area. This thesis also
suggests a load estimation calculation method to revise the
data base. It can make the system operation with more safe
and efficient. Distribution system in NCKU, feeders are
connected radially.In this research, the parameters
of this distribution system were determined to set up in
data base. Through the Z-loop load flow method and the
characteristic realization of this system, a suitable
restoration data base which is under any condition of all
possible outage areas has been established.
