摘要
结合南瑞新型发变组保护装置RCS - 985的功能特点 ,介绍了在华能威海电厂 #1机 1 2 5MW发变组是如何实现双套主保护、双套后备保护、双套异常运行保护配置方案 ,阐明了双主双后配置方案回路简单、运行维护方便的优点 ;提出了对TA。
This article introduces how to apply RCS-985 microcomputer-based protection to 125MW generator-transformer unit in HuanengWeihai Power Plant.This protection scheme uses redundant sets of main protection, back-up protection and abnormal protection of generator.Moreover, the advantage of simple circuit and convenience in operation of redundant sets of both the main and back-up protection schemes are illustrated. Especially proposes the configuration scheme of TV and TA is proposed. At last, this paper indicates the direction of redundant sets of main and back-up protection scheme in large generator-transformer unit.
