摘　　要：结合新型发变组保护装置 RCS- 985的功能特点 ,介绍了伊敏电厂 2号 5 0 0 MW发变组实现双套主保护、双套后备保护、双套异常运行的保护配置方案 ,详细论述了发电机内部故障主保护多重化配置的特点 ,阐明了双主双后配置方案回路简单、可靠性高、运行维护方便的优点 。This article introduces the configuration scheme of applying RCS 985 microcomputer based protection to 500 MW generator transformer unit in Yimin Power Plant, combining the characteristics of the RCS 985 protection. The protection scheme uses redundant sets of main protection, back up protection and abnormal protection of generators. Especially, the multi main protection characteristics of generator internal fault are proposed. Moreover, the advantage of simple circuit, high reliability and convenience in operation of redundant sets of both the main and back up protection schemes are illustrated. At last, the direction of redundant sets of main and back up protection scheme is indicated in large generator transformer unit.
