摘要
长输管道控制系统对意外停电和突然关阀等水击事故一般采取超前保护控制,对泵站意外停电水击事故状态进行了研究,以达到新稳态时管输量最大、全线总节流压力最小为最优原则确定目标函数,在稳态和瞬态模型的基础上,建立了选择水击事故超前保护最佳方案的数学模型,以实例求解管道中间泵站意外停电事故工况下超前保护的最优控制方案,并对其最优性进行了检验。
Lead protection control is generally applied to long distance pipeline control system for such water hammer accidents as accidental power-cut and sudden valve shutdown. Studies accidental status of water hammer like accidental power-cut at pumping station to get optimum principle, that is maximum pipe transporting volume under new steady state and minimum integral chock pressure over entire pipeline, and then takes these as objective function. Based on steady-state and transient-state models, establishes a mathematics model of lead protection optimum case used for water hammer selection to find a solution for a lead protection optimum case with actual examples under accidental power-cut operational condition at pipeline intermediate pumping station, and makes examination to its optimization as well.
