大型船舶变频供水管网压力平衡与控制策略仿真

摘要

为解决大型船舶供水管网压力不平衡问题,进行变频供水管网的仿真计算,分析管网压力平衡与控制策略,通过不同供水方式和不同控制策略的仿真,得出变频供水中采用增加高程分区的方式可以使末端用户用水的稳定性提高,最不利点恒压控制方式对末端用户流量调节效果更佳,有利于整个管网系统的相对稳定.%To solve the pressure imbalance problems of providing-water pipe network tor large ship,the prowding-water pipe network with frequency converter was simulated to analyze the pressure balance and control strategy.The simulation results of different water-supply modes and control strategy showed that by using a high-level district,the frequency converter can improve the stability of the end user,It can improve the relative stability of pipe network system,and it gives a better result of flow regulating for the end user,in the way of using constant-pressure control of the most adverse user.
