摘　　要：压水堆核电厂负荷跟踪模式能够有效协调机组产能与电网需求,延长燃料的循环寿期,提高机组运行的经济性能。反应堆系统具有高度复杂、非线性、时变等特点。通过合理简化,建立了反应堆系统集总参数模型,设计了负荷跟踪控制策略。引入负荷阶跃变化扰动和线性变化扰动,对反应堆负荷跟踪控制系统特性进行仿真。结果表明,控制特性与实际基本一致,控制系统能够满足负荷跟踪性能要求。Load-following model of PWR nuclear power plant （NPP） can correspond with unit product and electric network demand, prolong circle life of fuel and enhance economical performance of unit operation. The characteristic of nuclear reactor is high complex, nonlinearity and time-vary. The nuclear reactor system model of lumped parameter was built based on reasonable reduction, and control strategy of load-following was designed. Under phase step and linearly varying load disturbance, the characteristic of nuclear reactor load-following control system was analyzed. The results show that characteristic of control is consistent with practice, and control system is satisfied with the performance demand of load-following.
