汽轮机调节保护系统在主DCS中控制与操作逻辑的优化与应用

Optimization and Application of Control and Operation Logic of DEH and ETS System in Main DCS

江苏核电5、6号机组汽轮机调节和保护系统(以下简称P320)采用ALSPA P320 TGC系列产品,P320为自动控制系统,用于实现汽轮机的调节和保护功能,而机组主DCS采用广利核的Hollias-N平台。因此,P320与主DCS之间存在接口,用于实现运行人员在主DCS上对汽机相关逻辑进行操作。通过研究汽轮机调节和控制系统逻辑功能,对主DCS中的逻辑进行优化与实施。解决了原设计中控制操作功能无法实现的问题,保障了机组的稳定运行需求。

ALSPA P320 TGC series products are used in the steam turbine regulation and protection system of No.5 and No.6 of Jiangsu Nuclear Power Co.Ltd.P320 is an Automatic control system,which is used to realize the regulation and protection function of steam turbine.The main DCS of the unit adopts the Hollias-N platform of China Techenergy Co.Ltd.Therefore,there is an interface between the P320 and the main DCS,which is used to realize the operator to operate the turbine on the main DCS.By studying the logic function of DEH and ETS,the logic in main DCS is optimized and implemented.It solves the problem that the control operation function can not be realized in the original design,and ensures the stable operation of the unit.
