Abstract

The practice of tripping the generator breakers immediately following a boiler/turbine trip exposes a steam turbine generator to a potentially damaging overspeed operating condition. This paper describes the use of the sequential trip mode as a means of minimizing the exposure to possible unit damage following a boiler/turbine trip. Included is a comparison of the application of devices used by several major steam turbine generator manufacturers in accomplishing sequential tripping of the unit. This paper also discusses the differences in the devices used in implementing the tripping scheme and those applied as backup motoring protection. Additionally, the paper provides guidance in the selection of which functions should and should not be used to initiate sequential tripping.

汽轮机发电机的顺序脱扣

在锅炉/汽轮机脱扣后立即脱扣发电机断路器的做法会使汽轮机发电机处于潜在的破坏性超速运行状态。本文描述了使用顺序跳闸模式作为一种手段，以尽量减少暴露于可能的单位损坏后，锅炉/涡轮机跳闸。包括几个主要的汽轮发电机制造商在完成机组顺序跳闸时使用的设备的应用的比较。本文还讨论了跳闸装置与后备电动机保护装置的区别。此外，本文还提供了选择哪些函数应该和不应该用于启动顺序跳闸的指导。
