岭澳核电站蒸汽发生器水位控制系统改进方案仿真研究

Simulation Study on Improvement of Steam Generator Level Control System of Ling'ao Nuclear Power Station

利用核电厂瞬态分析和控制系统优化设计程序CATIA2,依据各典型瞬态试验验收的不同准则,通过核电厂典型瞬态下的数值仿真试验,为岭澳核电站解决主给水流量系统管路及调节阀振动问题拟采用的蒸汽发生器给水控制系统改进方案进行了仿真验证。结果表明:该改进方案可行,并且对反应堆控制系统所带来的影响是可接受的。

In order to solve the vibration problem of the main feedwater pipeline and control valve of Ling＇ao Nuclear Power Station, the steam generator level control system requires improvement. The improvement plan is analyzed and verified by using CATIA2 design program which used for analyzing the transient and optimizing control system of NPP, according to the NPP typical transient numerical simulation and the corresponding acceptance criteria. The simulation study results show that the improvement plan is feasible and the effect on the reactor control system is acceptable.
