摘　　要：结合锦屏二级水电站水轮发电机的特性,通过对水轮发电机全面的内部短路分析计算、定量化的设计过程,完成了主保护配置方案的设计,保护方案性能优异。实现了水轮发电机保护无动作死区,而且对所有实际可能发生的内部故障有2种及以上不同原理的主保护灵敏动作,为大型水电站水轮发电机的安全运行提供了可靠保证。Based on the characteristic of JinPing Ⅱ Hydropower Station hydraulic generators,the design of main protection configuration scheme for hydraulic generators of JinPing Ⅱ Hydropower Station is completed through overall internal short-circuit calculation and quantitative design process.The protection performance is excellent.It implements not only no dead zone for protection act,but also more than two kinds of main protection acting for any internal fault.So it is helpful to provide reliable assurance for safe operation of large generators.
