Based On The Principle Of Data Driven And Predict Electrolytic Optimization Control System Design

Aluminum is a high energy consumption industry. With world energy supply increasingly tense and people environment consciousness continuously enhance, national policy rigid regulations, Clean, efficient and highly intelligent control become the main direction of technology development, as electrolytic aluminum industry.View of the current electrolyzer how different implementations of energy saving ideas, this article according to Chalco Guizhou Branch 160kA Study for the electrolytic cell monitoring system to collect historical data and real-time data, Proposed a set of electrolytic cell line optimization control strategy. First of all, using data mining algorithms based on Real-time database for electrolyzer, from large disorderly high noise electrolyzer run data unearthed reflect electrolyzer state relations, combining craft expert knowledge research electrolyzer state system and each state diagnostic basis and use state system based, reasoning different state electrolyzer control optimization Strategy. Achieve energy saving and prolonging life purpose through the electrolytic cell electrolytic cell process system optimization. Determine the concentration of the alumina to the electrolytic cell is different from the previous only in accordance with the apparent resistance to infer the concentration range. Proposed electrolyzer state and out aluminum Biomass as affect alumina concentration factors and binding groove resistor slope use based orthogonal transform classic linear prediction method infer next moment alumina concentration. Through electrolyzer state accurate judgment and concentration range forecast original Slot Control machine control strategy accession fuzzy reasoning machine thus better control feeding interval (NB) and electrolyzer set voltage reduce anode effect occurrences so electrolysis process maintain energy balance and material balance between, achieve energy saving purposes.The optimal control system in aluminum smelters to be test in Guizhou branch, after three months of operation and technology experts to obtain good results. On electrolyzer trough work conditions judgment accuracy than 90%; To judge the accuracy of the alumina concentration has reached more than 95%; enable electrolyzer alumina concentration correlation greatly enhanced, Significantly reduced the number of anode to action, realized ton aluminum saving 200 degrees.
