There is a wide variety of system and applications in the power system. However, they have compatibility issues because they use different data standard and communication method. With the introduction of the smart grid, power system has been grow and diversified. Therefore power system need to be compatible with each other and the interoperability between applications is increasingly important. Thus, the IEC established IEC61970 and CIM Standard data exchange model for interoperability and system integration. Server-Client system was constructed which using CIM HSDA(Part4), a standard communication model, presented in IEC 619710. Also, self-developed real-time voltage stability analysis application and contingency analysis application was used. CIM HSDA was used for data input and real-time analysis. Tolerance of result which is in the range of allowable derived by Perform real-time voltage stability and contingency analysis of Jeju power system, and then compare it’s result with PSS/E result.

신재생에너지를 이용한 분산전원이 연계된 배전계통에 여러 가지 문제점이 발생한다. 분산전원에서 공급된 고장전류에 의하여 발생되는 단락용량의 증대, 고장조류의 다양화로 보호기기의 오작동, 연계선로의 고장파급 등의 문제는 기존 단방향 조류와 시간차를 이용한 보호협조 방식으로는 해결할 수 없다. 그러므로 고장 전류의 조류방향을 판별할 수 있는 방향성 보호기기의 도입이 요구되고 있다. 따라서 본 논문에서는 기존에 개발된 양방향 조류해석 및 고장해석 시뮬레이션 프로그램(Off-DAS)를 사용하여 분산전원이 연계된 계통의 고장 해석을 실시하고 방향성 판별 알고리즘을 적용한 보호기기(리클로져, 다회로 차단기)의 실증시험을 통하여 Off-DAS프로그램의 성능을 입증하고 방향성 판별 알고리즘에 대하여 분석하고자 한다.
