电加热杆抽油作为一种有效的开采稠油的方法,具有设备简单、操作方便、加热效果好、成本低等一系列优点。针对电加热系统,提出了加热对象的数学模型;通过仿真实验对两种不同最优准则下进行了比较研究,得出时间平方加权的误差平方积分(ISTTE)准则下的控制方法,仿真结果表明该方法可以缩短系统的调节时间,有效地抑制系统的超调,从而为提高稠油电加热系统的加热效率提供了一种参考。
Electric heating rod pumping as an effective method of heavy oil exploitation, with simple equipment, easy operation, good heating effect, low cost and a series of advantages. Aiming at the electric heating system, a mathematical model of the heating object is proposed. By comparing the two different optimal criteria through simulation experiments, the control method under the ISTTE criterion is obtained. The simulation results show that The method can shorten the regulation time of the system and effectively restrain the overshooting of the system, thereby providing a reference for improving the heating efficiency of the heavy oil electric heating system.
