| Summary: | 碩士 === 國立高雄應用科技大學 === 電機工程系 === 97 === This study aims at the setting of the directional overcurrent relay of the 69kV transmission line of Taiwan power company. Current settings of the overcurrent relay are decided by manpower based on the relay principles set by Taipower. To shorten the calculation time, we applied genetic algorithm to find the optimal setting of directional overcurrent relay. A Taipower 69kV system in Wu-jia City of Kaohsiung County is selected for computer simulation to demonstrate the effectiveness of the proposed methodology. It is found that the proposed genetic algorithm methodology provides more accurate setting values than conventional calculation. Through comparing with the results gained from the traditional calculation, the researcher proved that genetic algorithm was more accurately capable of finding setting values. In addition, this finding is able to enhance working efficiency.
