Abstract

In alumina production, the electric drive system accounts for a significant portion of energy consumption, and the level of automation directly impacts production efficiency and costs. The electric drive system in alumina plants faces issues such as high equipment energy consumption and insufficient automation control accuracy. By adopting high-efficiency energy-saving motors and intelligent variable frequency speed control technology, the system can achieve energy-saving optimization. Combining PLC and distributed control systems enhances automation control levels, improving sensors and communication networks to ensure data transmission, and optimizing control algorithms for precise control. Practical tests have shown that this strategy effectively reduces system energy consumption, improves production stability and control accuracy, and provides a viable path for the intelligent and green development of alumina plants.
