摘　　要：对汽包双室平衡容器水位温压补偿控制系统进行了探讨和研究,根据温压补偿模型,分析了P L C系统难以独立实现的原因以及查表法的缺陷,提出了P L C系统与上位机系统相结合的水位温压实时连续补偿的综合控制策略,提出并分析比较了三种体系结构及其实现原理和技术,工程应用结果表明该控制系统提高了水位控制的实时性、稳定性、准确性和安全性。This paper discusses and analyses the drum level control system of temperature and pressure compensation for double- chamber balancing container. Due to the limitations of PLC programming language and the defects of look-up table method, the paper proposes the real-time, continuous, integrated control strategy combining PLC and PC based on the m,3del of temperature and pressure compensation. The paper proposes three kinds of software architecture and realization methods through analysis and comparison. The result of engineering application shows that the control system improves the real-time capabilities, stability, accuracy and security of drum level control.
