摘要:
二氧化碳在高压下接近临界状态时具有显著的非线性特性,使得二氧化碳管输增压泵前泵的微小调节会引发相变风险,难以将控制增量施加于前增压泵,使得输出压力的超调量较大。为此,开展二氧化碳管输增压泵自动化控制技术的研究。使用具有控制结构的单片机获取管输过程中二氧化碳压力信号,通过增量式数字PID(比例积分微分)控制算法,以近3次的二氧化碳增压泵输出二氧化碳压力信号和理想压力的差值,得到二氧化碳管输增压泵压力控制增量,将控制增量施加于前增压泵,调整增压泵输出压力,维持二氧化碳管输所需压力,实现增压泵自动化控制。实验结果表明,所提方法在压力调控过程中响应迅速、曲线平滑,能够从初始值快速过渡到8 MPa并迅速趋于稳定;系统能耗从8.2 kWh/t降至7.5 kWh/t,压力波动频次从2.1次/h降至2.0次/h且波动小,3个月内增压泵维修次数降至0次,管道压力稳定在7.9 ~ 8.1 MPa,波动不超0.1 MPa,系统响应时间最长仅为12.5 ms。
Abstract:
When carbon dioxide approaches the critical state under high pressure,it exhibits significant nonlinear characteristics.This makes minor adjustments to the front pump of the carbon dioxide pipeline booster pump prone to phase change risks,and it is difficult to apply the control increment to the front booster pump,resulting in a large overshoot of the output pressure.For this purpose,research on the automatic control technology of carbon dioxide pipeline booster pumps is carried out.The carbon dioxide pressure signal during the pipeline transportation process is obtained by using a single chip microcomputer with a control structure.Through the incremental digital PID(proportional integral derivative) control algorithm,the pressure control increment of the carbon dioxide pipeline transportation booster pump is obtained by taking the difference between the output carbon dioxide pressure signals of the carbon dioxide booster pump in the recent three times and the ideal pressure.The control increment is applied to the pre booster pump.The output pressure of the booster pump is adjusted to maintain the required pressure for carbon dioxide pipeline transportation and achieve automatic control of the booster pump.The experimental results show that the studied method responds rapidly,it has a smooth curve and it can stabilize quickly when transitioning from the initial value to 8 MPa in pressure regulation.The system energy consumption has decreased from 8.2 kWh/t to 7.5 kWh/t.The frequency of pressure fluctuations has dropped from 2.1 times per hour to 2.0 times per hour with small fluctuations.The maintenance frequency of the booster pump has decreased to 0 times in March.The pipeline pressure has been stable at 7.9—8.1 MPa,with fluctuations not exceeding 0.1 MPa.The longest system response time is only 12.5 ms.
