摘 要:【目的】随着民航需求与日俱增,大中型机场数量增加,安全稳定的机坪管网供油系统是实现民航机场人享其行、物畅其流的基石,精准的启停泵控制方案是保障恒压供油自动控制系统高效运行的核心。【方法】采用特征线法编制机坪管网供油系统离线仿真程序,并与SPS软件结果进行对比,验证了所编制程序的准确性。以中国某机场实际管网结构和加油信息为例,针对不同控制模式(单泵变频、多泵变频)、不同测量参数(压力频率、压力流量)的控制方案,考虑该机场一天内加油流量变化,模拟得到不同控制方案下油库出口压力、加油泵运行状态随时间的变化情况,统计得到启停泵次数与泵机组运行能耗并进行对比分析。【结果】基于压力频率测量参数进行控制时,系统倾向于启动更多的加油泵以应对压力波动,因此其最大运行泵数高于基于压力流量测量参数控制。启停泵控制的关键是保障加油需求与运行泵数匹配,停泵更及时的控制方案能够有效减少能量损耗。综合考虑,多泵变频控制模式能够在停泵工况下通过调节泵转速来保障管道压力稳定,且基于压力流量测量参数进行启停泵判断时能够显著降低运行能耗,提高系统运行的安全性与经济性。【结论】研究成果能够辅助设计和运行人员进行泵启停控制方案优选,有利于机场加油系统的合理规划设计、安全调度管理及精确操作控制。(图8,表3,参20)[Objective]With the rising demand in civil aviation and the continual growth of large-and medium-sized airports,reliable and secure apron hydrant pipeline systems are essential for enabling the smooth movement of passengers and cargo at civil aviation airports.Furthermore,an accurate pump start/stop control strategy is vital to ensuring the eficient operation of an automated control system for oil supply at constant pressures.[Methods]An offine simulation program was developed utilizing the characteristic method for hydrant pipeline systems.This program was then cross-checked against SPS software results to validate its accuracy.Subsequently,within the setting of an airport in China,encompassing its actual pipeline network structure and refueling data,simulations were conducted,incorporating different control modes(single-pump frequency conversion and multi-pump frequency conversion)and diverse measurement parameters(pressure-frequency and pressure-flow).Accounting for fluctuations in refueling flow at the airport over a single day,these simulations generated the time-varying outlet pressures at the depot and operational states of refueling pumps under different control strategies.The subsequent statistical analysis enabled the derivation of pump start/stop frequencies and energy consumption associated with pump unit operations for further comparative evaluation.[Results]In control scenarios utilizing pressure-frequency measurements,the system tended to initiate refueling pumps more frequently to manage pressure fluctuations,leading to a higher maximum number of operating pumps compared to scenarios based on pressure-flow measurements.The core objective of pump start-stop control is to align the number of operational pumps with the refueling demand.Additionally,implementing a control strategy that halts pumps more timely presents an effective solution for reducing energy losses.A thorough analysis highlighted the efficacy of the multi-pump variable frequency control mode in maintaining stable pipeline pressures t
