Field experience of distribution automation system (DAS) in Korea electric power corporation (KEPCO)

摘要

From the viewpoint of the distribution system, distribution automation (DA) is one of the important functions in Smart Grid (SG) technology. In this paper, the field experience of DAS in KEPCO is briefly described. Note that there is a significant difference in DAS between theory and practice since DAS is achieved using computer and communication technology, advanced software, and remotely operable high voltage switch gear based on real-time. DAS in KEPCO has been continuously modified for over 20 years in accordance with the suggestions of numerous operators in Distribution Control Center (DCC). The basic concept of DAS presented in the paper strongly supports power utilities in developing their own DAS more confidently and efficiently with less trial and error.
