摘　　要：单一功率水平处的堆芯模型无法准确地代表堆芯不同功率工况下的动态特性。为了解决这一问题,利用三角形隶属度函数对5个不同功率水平下的局部模型进行加权,建立堆芯模糊多模型,并开发模糊多模型仿真系统。以压水堆堆芯为对象,开展堆芯反应性和冷却剂进口温度的扰动仿真。结果表明,建立的堆芯模糊多模型仿真系统可适用于堆芯不同功率水平的仿真。The reactor core model for a single power level can not accurately represent the dynamic characteristics of the core under different power conditions.In order to solve the problem,the triangle membership function is used to weigh five local models at different power levels,and the fuzzy multi-model simulation system is developed.Taking the PWR core as an example,the disturbance simulation of the reactivity and the coolant inlet temperature are carried out.The results show that the fuzzy multi-model simulation system can be applied to the simulation of different core power levels.
