摘要
针对机组和主接线自身特点,详细说明了大岗山水电站水轮发电机组发变组保护组屏方案和功能配置,并介绍了变斜率差动保护和注入式定子接地保护原理及保护出口跳闸方式,为类似工程的设计和实施提供参考。
In view of the characteristics of hydrogenerator and main wiring of Dagangshan Hydroelectric Power Plant, the configuration scheme and functions of hydrogenerator-transformer unit protections are introduced in detail. The principles of variable-slope differential protection and injecting stator grounding protection and the outlet trip way are also studied. The practices can provide references for the design and implementation of similar projects.
