现代计算机控制系统技术的飞速发展,使得以此为基础的微机继电保护装置的自动化程度和测量采样精度越来越高,汽轮机与发电机的联锁保护的实现更加简化,保护功能的区分更加细化,继电保护的正确动作率得到了显著提高.以微机继电保护为基础,以50 MW发电机保护配置及出口动作情况为例,并以相关设计规范和实际标准为依据,分析了发电机和汽轮机配置联锁保护的意义,通过对当前运行的发电机和汽轮机保护现状分析,提出了梳理保护配置和规范保护联锁动作的建议.“,”The rapid development of technology on modern computer control system caused super automatization on microcomputer relay protection system and higher precision on sampling and measurement. The program of electric interlocking protection for electric generator and turbine was simplified, the distinction of the self-protective function was refined, and the correct operation rate of the relay protection system was notably improved. Based on microcomputer relay protection system,the protective configuration and the output action for 50 MW electric generator were took as example, the significance of generator and turbine configuration interlocking protection were analyzed according to design criterion and standards of electric specialty. Based on the analysis of the generator and turbine protective operation, an proposal of summarizing the protective configuration and standardizing the interlocking protective operation were put forward.
