摘　　要：为实现管道运行的安全平稳控制,长距离输油管道调度过程中应该采用有效控制策略、运行波动最小控制策略和全线节流最小策略。阐述了每个优化控制策略的具体意义,有效控制策略是通过恰当调节进出站压力设定值,使管道系统处于被有效控制的状态;运行波动最小策略是使管道沿线压力、流量波动尽可能小;全线节流最小策略是使全线能量浪费最少。给出了实际调度过程中可以借鉴的控制方法,对全线节流最小的控制目标给出了数学模型。这些调度优化控制策略可以有效指导中控调度员的控制操作,提高安全、平稳、高效调控的能力。In order to control the operation of pipeline safely and steadily, the strategies of effective control, minimum operation fluctuations and minimum throttling along the pipeline should be adopted in the scheduling of long-distance pipeline. This paper expounds on the significance of each strategy. In particular, the effective control strategy is to keep the pipeline system be controlled effectively by appropriately regulating the inlet or outlet pressure setting of input and output terminals stations, pipeline system is in a state of being effectively controlled; the operation with minimum operation fluctuations control strategy is to minimize the fluctuations of the pressure and flow along the pipeline if possible; the minimum throttling strategy is to minimize the energy waste along the pipeline. Some control methods are showed as reference for actual scheduling process, and a mathematical model is presented as to the control objective of the minimum throttling along the pipeline. These optimal strategies can effectively guide the control operation of central dispatcher and improve the ability of safe, steady and efficient control.
