摘要
根据联合站原油脱水过程的工艺特点及控制系统的要求 ,建立了系统的动态数学模型 ;研究了输出变量与输入变量之间的关系及对干扰的响应 ,改变了原油脱水过程控制方案中的输入、输出变量间的对应关系 ;基于此配对原则设计的控制系统 ,在大庆油田联合站实际应用过程中 ,系统的可控性和闭环系统的稳定性得到明显提高 .原油脱水过程工艺特性的研究 ,为改进原油脱水过程的控制方案提供了技术指导 .
According to the technological characteristics of crude oil dewatering process and the requirement of control system, a dynamic mathematical model of crude oil dewatering process is established. By studying the relation among the system variables and the disturbance response of output, corresponding relation between input and output was changed during the control system design. Practical application of the control system in joint station of Daqing oil field shows that the controllability and the stability were greatly improved. It is useful to improve the control scheme of oil\|water separation.
