摘　　要：目前,油库管道阀门进行现场操作时大多结合工程经验与SCADA数据进行试探性调节,具有一定的盲目性,阀门调节时间长、风险大。为了制定压头约束下油库管道复杂水力系统中阀门的调节方案,根据油库管道系统的通用物理模型,结合水力瞬变相关理论,建立阀门调节过程的数学模型,并根据实际工况,确定对应的定解条件。结合有限差分法和空间特征线法,针对存在变径点、泵、阀等元件的复杂油库发油管路系统,基于反问题相关理论,求解压头约束下以调节时间最短为目标的阀门控制方案,从而为复杂水力系统中阀门的控制优化提供借鉴。(图6,表3,参20)Currently, the field operation of valves in depot pipelines is mostly the trial regulation based on the engineering experience and SCADA data, so it is blind to some extent with long regulation time and great risk. In order to work out a controlling scheme for the valves in complex hydraulic system of oil depot pipelines under the constraint of pressure, a mathematical model for calculating the valve regulating process was established based on the general physical model of pipeline system in oil depots, combined with the hydraulic transient theories. Then, the corresponding definite conditions were determined according to actual working conditions. Finally, for the complex oil discharge pipe system of oil depot with variable diameterpoint, pump and valve, the valve controlling scheme with the minimum regulation time as the objective function under the constraint of pressure was formulated based on the theory of inverse problem, combined with the finite difference method and the spatial characteristic line method. The research results provide a reference for the optimal control of valves in complex hydraulic systems.
