摘　　要：针对集中空调系统变静压控制策略中静压设定参数难以确定的问题及系统依赖性特征,提出基于末端阀位开度控制的变静压变步长控制策略,通过仿真实验对其控制过程及系统性能进行分析。利用实验平台相关参数构建动态仿真模型,设计变步长静压调整方法,根据最不利末端的阀位开度信息在线调整静压增减幅度,进而确定变静压变步长控制策略,分别在稳态及动态温度控制方案下进行仿真研究。结果表明所提出的策略比传统变静压定步长控制策略的调整次数减少23%,系统能耗降低3.9%。Aiming at the hardly determined static pressure setting parameter in the variable static pressure control strategy of the central air conditioning system and the characteristics of system dependence, a variable static pressure and variable step control strategy based on terminal damper position control is proposed. The control process and system performance are analyzed by simulation experiment. The dynamic simulation model is constructed by using parameters of the experimental platform. The variable step static pressure adjustment method is designed to adjust the increase or decrease of static pressure online according to the valve of damper position at the most unfavorable terminal. Thus, the control strategy of variable static pressure with variable step is constructed, and the simulation research is conducted for steady-state temperature control and dynamic temperature control respectively. The results show that compared with the traditional variable static pressure control strategy, the adjustment times and the energy consumption of the proposed control strategy are reduced by 23% and 3.9% respectively.
