CPR1000核电厂汽轮机旁路排放系统控制模式优化研究

Study on Control Mode Optimization of the Turbine Bypass System in CPR1000 Nuclear Power Plant

摘要: CPR1000核电厂气轮机旁路系统GCT在高功率下使用温度控制模式（T模式）使核电厂能够适应气轮机负荷的快速、大幅变化，从而避免反应堆紧急停堆。通过对压力控制模式（P模式）的优化，使其满足高功率下的控制需求，并利用系统分析程序GINKGO分别对两种模式的控制性能进行了数值模拟与分析。研究结果表明：优化的P模式控制性能优于T模式，并且具备优化排放容量的潜力，有利于提高GCT的控制性能和经济性。

Abstract: The Mode T at high power level is used by the turbine bypass system（GCT） of CPR1000 nuclear power plant, which can make the nuclear power plant adapted to the rapid and large turbine load change to avoid reactor trip. The Mode P is optimized to meet the control requirements at high power level. The control performance of the two modes is numerically simulated and analyzed by the system analysis code GINKGO. The results show that the optimized Mode P is better than the Mode T, and it has the potential to optimize the emission capacity, which is beneficial to improve the control performance and economy of GCT.
