摘要
分析了传统发电机定子和转子接地保护应用在超超临界机组上的不足,在此基础上提出了更加完善的定子和转子接地保护方案,建议采用注入式定子接地保护和注入式转子接地保护原理,实现不受发电机运行工况影响的定转子绝缘检测。
This paper analyzes the shortage of conventional generator stator and rotor earth fault protection applied to ultrasupercritical generating unit. A novel stator and rotor earth fault protection scheme is proposed subsequently, and voltage injection type stator and rotor earth fault protection are commended, which are immune to the operating condition of generator.
