摘　　要：为了研究凝结水系统跟踪仿真系统的问题,首先在模块化建模系统仿真平台中建立了凝结水系统的动态模型,然后对影响跟踪变量的模型参数进行敏感性分析,确定在线跟踪机制的控制变量为除氧器压力和各加热器壳侧压力,最后设计基于比例积分(proportional integral,PI)控制算法的在线跟踪仿真系统。通过调节所设计PI控制器的参数,实现对除氧器和各加热器壳侧压力的精确快速跟踪。结果表明,通过选取合适PI控制器参数,所设计的凝结水在线跟踪仿真系统能够有效实现除氧器和各加热器壳侧压力对抛物线形和阶梯形信号的跟踪。To address the problem of the tracking simulation system of the condensate system, it first establishes a dynamic model of the condensate system in the Modular Modeling Syste(MMS). It then conducts a sensitivity analysis on the model parameters affecting the tracking variables, identifying the deaerator pressure and shell side pressure of each heater as the control variable.Subsequently, an online tracking simulation system based on PI controller is designed. By adjusting the parameters of the designed PI controller, the system achieves precise and rapid tracking of the deaerator pressure and the shell side pressure of each heater. The results show that, by selecting appropriate PI controller parameters, the online tracking simulation system of the condensate system can effectively track the parabolic and stepped signals.
