154㎸ 디지털변전소 준공을 위한 엔지니어링 및 수행결과 분석에 관한 연구

In June 2013, 154㎸ digital substation based on IEC61850 was established for the first time in South Korea. In 2016, digital substation of about 26 plants have operated all over the nation. A new technology called IEC61850-based substation automation successfully applied to a real system. Since the early 2000s, to apply a new technology called IEC61850-based substation automation successfully to a real system, we (KEPCO) have been developing the engineering and performance verification technology related to fields. In this paper, we illustrate our engineering experience with the contents of the analysis and verification results, also various field problems that have occurred in the field during the past years. Finally we suggest a useful information that can be considered when the new substation is installed.
