【摘要】：随着企业生产规模的扩大和工程量的增长,原先企业设计人员通过人工设计手段来实现电气选型设计的方法己经跟不上如今大量复杂的工程管理要求,并且人工设计的方法过分依赖于经验的积累,设计周期较长,精度不高,不利于大型工程的设计。多年来,鞍钢集团信息产业有限公司承担了鞍钢以及国内外信息化系统设计、制造、技术研发、设备安装、调试及国家重点科研项目的攻关任务,积累了大量的设计知识,急需将这些经验知识管理并复用,计划建立电气设计平台项目,以期实现电气设备选型设计自动化,提高产品选型的效率,解决企业急待解决的焦点问题。变频器选型设计是其中一个重要环节,因为随着变频调速技术的发展,变频器已经广泛地应用在鞍钢的冷轧、热轧、高炉、转炉等各条生产线上,对生产影响巨大。变频器的选型也会直接影响着生产的可靠性和工作效率。但是,不同的应用场合,不同的工况下变频器的选型不同,而变频器选型需要分析的因素复杂繁多。针对上述问题,通过分析目前变频器产品选型技术研究现状,并结合鞍钢的实际情况,在电气设计平台的基础上提出并完成了基于知识复用技术的变频器选型方法及选型平台设计,研究了知识复用和产品选型设计的理论。通过对基于知识复用设计的研究,分析了知识复用在选型设计尤其是变频器选型设计中的应用。采用知识复用技术构建了电气设备选型平台,并分析了基于知识复用技术的电气设备选型平台的开发过程,探讨了系统的体系结构及功能模块,对系统结构中的变频器的选型及资源管理进行了重点的分析和设计。并以鞍钢冷轧厂连退线为例,验证了基于知识复用技术的变频器选型方法的可行性和有效性。
[Abstract]:With the expansion of enterprise production scale and the increase of engineering quantity, the methods used by enterprise designers to achieve electrical type selection and design through manual design have been unable to keep up with a large number of complex engineering management requirements.The artificial design method is too dependent on the accumulation of experience, the design cycle is longer and the precision is not high, which is not conducive to the design of large engineering.Over the years, Angang Group Information Industry Co., Ltd. has assumed the task of design, manufacture, technology research and development, equipment installation, commissioning and key scientific research projects at home and abroad, and has accumulated a lot of design knowledge.It is urgent to manage and reuse these experiential knowledge and plan to set up the electric design platform project in order to realize the automation of electrical equipment selection and design, to improve the efficiency of product selection and to solve the urgent problems to be solved by enterprises.The design of frequency converter selection is one of the important links, because with the development of variable frequency speed regulation technology, frequency converter has been widely used in the cold rolling, hot rolling, blast furnace, converter and other production lines, which has a great impact on production.Frequency converter selection will also directly affect the reliability and efficiency of production.However, the frequency converter selection is different under different working conditions in different application situations, and the factors that need to be analyzed are complicated.In view of the above problems, through the analysis of the current research status of inverter product selection technology, and combined with the actual situation of Angang,On the basis of electrical design platform, the selection method and platform design of frequency converter based on knowledge reuse technology are put forward and completed, and the theory of knowledge reuse and product selection design is studied.Based on the research of knowledge reuse design, the application of knowledge reuse in type selection design, especially in frequency converter selection design is analyzed.The electrical equipment selection platform is constructed by using knowledge reuse technology, and the development process of electrical equipment selection platform based on knowledge reuse technology is analyzed, and the system structure and function module are discussed.The selection of frequency converter and resource management in the system structure are analyzed and designed.The feasibility and effectiveness of the frequency converter selection method based on knowledge reuse technology are verified by taking the continuous winding line of Angang cold rolling mill as an example.
