摘　　要：电解铝企业原有的槽控制技术基于单一的电阻信号来判断电解槽运行是否稳定,无法达到可视化效果,缺乏协同控制、优化决策、异常情况诊断的功能。随着电解槽槽型逐步大型化,出现了愈来愈多仅靠人工经验而无法提前预判的问题。以电解铝企业400 kA系列电解铝为研究对象,开发了新型数字槽控机,介绍了新型数字化操控系统的组成及功能,并将该系统进行了实践运用。研究表明,在新型数字化槽控制系统的配合下,400 kA系列电解槽突发事件的预防能力和生产稳定性大幅提高,电能耗损、生产原料成本显著下降,人工效率和电解槽运行的稳定性显著提升。The original cell control technology of electrolytic aluminum enterprises is based on a single resistance signal to judge whether the operation of the electrolytic cell is stable,which cannot achieve the visual effect,and lacks the functions of collaborative control,optimization decision-making and abnormal situation diagnosis.With the gradual enlargement of the electrolytic cell type,there are more and more problems that cannot be predicted in advance only by manual experience.Taking 400 kA series electrolytic aluminum of electrolytic aluminum enterprise as the research object,a new digital slot control computer was developed.The composition and function of the new digital control system were introduced,and the system was applied in practice.The research shows that with the cooperation of the new intelligent optimization control system,the prevention ability and production stability of the 400 kA series electrolytic cell emergencies are greatly improved,the power consumption and the cost of production raw materials are significantly reduced,and the labor efficiency and the stability of the electrolytic cell operation are significantly improved.
