汽机旁路系统蒸汽阀反馈波动紧急干预方案

Emergency Intervention Scheme for Steam Valve Feedback Fluctuations of Turbine Bypass Discharge System

基于全数字化仪控系统在核电厂的应用,提出一种针对机组降功率过程中汽机旁路系统蒸汽阀反馈波动的紧急干预方案,该方案能够保证机组降功率及停机解列按照计划及外部要求顺利进行,避免机组参数出现大幅波动。

Based on the application of full digital I and C system in nuclear power plant,an emergency intervention scheme for steam valve of contournement global turbine feedback fluctuations in the course of unit power reduction is proposed which can ensure the smooth operation of unit power reduction and shutdown disconnection according to the plan and external requirements,and avoid large fluctuations of unit parameters.
