超超临界汽轮机主蒸汽压力选择模块的优化

Optimization of Selection Module for Main Steam Pressure in Ultra-Supercritical Steam Turbines

介绍了超超临界汽轮发电机组主蒸汽压力实际值的形成,通过描述发生在国内某电厂的跳机事故,分析了在传感器故障及测量值偏差等各种工况下,单侧主蒸汽压力实际值的选取逻辑,并对相应逻辑进行变更优化。研究成果有利于汽轮发电机组更稳定、安全的运行。

The formation of main steam pressure actual value of ultra-supercritical steam turbines is presented. Based on the trip accident occurred in a domestic power plant, the selection logic of the main steam pressure actual value is analyzed for sensor failure and deviation of measured value under various conditions, and then,the corresponding logic is optimized. The research results have a benefit to operation stability and safety of steam turbine generator units.
