발전기 보호계전 요소분석과 기본 알고리즘 검증에 관한 연구
趙誠振,崔勉松,李承宰 明知大學校 産業技術硏究所 2004 産業技術硏究所論文集 Vol.23 No.-
In consequence of the fact that the power plant the wattmeter from most as the wattmeter general interpretation focus facility which takes charge of the stable production and a supply of the war potential which is important it minimizes the damage of accident occurrence hour and the hazard which protects a healthy channel high the accuracy and reliability are demanded. In this paper analyzed the operational elements of generator promotion of virtue conclusion protection ratio differential relay (87G), Earth current differential relay (87GN), Revers power relay (32),Synchronization relay (25), automatic Synchronization relay (25A), frequency relay (81) from the dissertation which it sees and the maul trap to grasp a basic principle it led and a basic algorithm it verified. This paper is dissertation which it sees leads and there is a place where it develops the basic algorithm which it follows in protection element analysis and operational for the domestic technical development of the generator protection relay field which depends in advanced foreign nation production company quality.
