为了深入理解船舶冷媒水管网系统在更多运行条件下的性能以及控制策略的特性，基于在FloMASTER中搭建的冷媒水管网数值模型，进行了末端变流量PID控制策略及泵支路压差旁通PID控制策略的模拟分析。对末端变流量控制策略进行模拟，结果表明采用末端变流量PID控制策略可以很好地控制末端的按需流量。多末端同时调节时，阀门控制会产生干涉现象，但各末端流量仍能很好控制。泵支路压差旁通控制策略模拟结果表明这种策略在维持系统流量和压差稳定性方面具有显著效果。研究结果为实际应用提供了理论依据和设计指导。
In order to gain a deeper understanding of the performance and control strategy characteristics of the refrigerant water pipe network system under various operating conditions, this dissertation conducted simulation analysis of the end variable flow PID control strategy and the pump branch pressure difference bypass PID control strategy based on the numerical model of the refrigerant water pipe network built in FloMASTER. The simulation of the end variable flow control strategy showed that the end variable flow PID control strategy can effectively control the on-demand flow at the end. When multiple ends are adjusted simultaneously, valve control may cause interference, but the flow at each end can still be well controlled. The simulation results of the pump branch pressure difference bypass control strategy showed that this strategy has significant effects in maintaining system flow and pressure difference stability. The research results provide theoretical basis and design guidance for practical applications.
