碩士 === 南榮技術學院 === 工程科技研究所碩士班 === 101 === The power distribution feeder automated system can effectively improve the reliability of power and reduce the required time to operate the manually operated switches. Especially, applying the expert program FDIR, the system has the functions of telemetry, monitoring, and remote control to detect feeder fault. When the accident occurs, the system will operate automated switches automatically to isolate the fault section by the program logic operation results, narrow the section of power outages and reduce load transfer time of operated switches effectively such that the power is restored quickly in healthy section. The power distribution feeder automated system can work only if the messages that provide to FDIR from Feeder Terminal Unit (FTU) are accuracy. One of the important factors is the setting for Time Coordination Curve (TCC) of FTU. In this paper we discuss how to set TCC to reduce the misjudgment of FDIR. And we propose a criterion to reach the optimal setting for TCC. Finally, we apply the Simulated Annealing Method to calculate the set point more to meet the future demand for the technology upgraded of FTU.
