【摘要】 小型压水堆运行环境复杂、运行工况灵活多变，需要更强的抗干扰能力以及更快的负荷跟踪响应速度。为建立适用于全局的堆芯功率控制系统，基于堆芯模糊多模型，设计堆芯功率模糊控制器，建立堆芯功率模糊控制系统，并开展堆芯进口温度阶跃扰动、堆芯功率阶跃变化等工况仿真。结果表明，设计的小型压水堆堆芯功率模糊控制系统适用于堆芯全局范围内的动态响应，能达到较为理想的控制效果。更多还原

【Abstract】 With a complex operating environment and flexible operating conditions, a small pressurized water reactor(PWR) requires stronger anti-interference ability and faster load following response speed. To establish a global core power control system, based on the fuzzy multi-model of reactor core, the core power fuzzy controller is designed, and the core power fuzzy control simulation system is established. Then the working conditions such as core inlet temperature step disturbance and core power reference step change are simulated. The results show that the designed core power fuzzy control system of small PWR is suitable for the global dynamic response of the reactor core, which can achieve ideal control effect.更多还原
