Study on Automatic Control Method for Clod Start-up of Nuclear Power Plant

针对核动力装置冷启堆自动控制问题,确定总体控制策略,并采用不同控制方法,分别设计启堆过程不同阶段的一回路平均温度、稳压器温度、压力、水位,以及蒸汽发生器(SG)二次侧蒸汽压力的控制算法;采用基于RELAP5和SIMULINK的核动力装置控制综合仿真平台对启堆过程进行仿真计算。结果表明,所设计的控制方法能够实现反应堆从冷态停堆到具备带负荷运行条件的全过程自动控制,并满足启堆操作规程和安全性的要求。

The overall control tactics for the automatic clod start-up of nuclear power plant is discussed in the paper. Then, different control methods are designed to realize the auto-control of the primary loop coolant temperature, the levels of the temperature, the pressure and the water of the pressurizer, and the steam pressure of SG, respectively, in different phases. The control effects are demonstrated using a comprehensive nuclear power plant control simulation platform based on the RELAP5 and SIMUL1NK. The simulation results show that with the designed control methods, the automatic control of the nuclear power plant start-up from cold shutdown can be realized, and the requirements of operating regulations and safety can be satisfied.
