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.
