中文摘要:
      为了研究凝结水系统跟踪仿真系统的问题,首先在MMS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。
英文摘要:
      In order to study the problem of the tracking simulation system of the condensate system, the dynamic model of the condensate system is first established in the MMS, then sensitivity analysis of the model parameters affecting the tracking variables was carried out, the control variable was the pressure of deaerator and shell side pressure of each heater, finally design an online tracking simulation system based on PI controller. By adjusting the parameters of the designed PI controller, accurate and fast tracking of the pressure on the shell side of the deaerator and each heater can be realized. 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.
