Application analysis of electrical engineering automation control under PLC technology

With the rapid development of computer control technology and automation control technology, traditional control methods can no longer meet the needs of the market, and analog control technology will also be replaced. PLC technology is widely used in metallurgy, chemical industry, petroleum, steel and other industries. It enhances the stability, reliability and safety of the control system. At the same time, it is also very important to promote energy conservation and environmental protection, improve the environment, and promote scientific and technological progress. The main purpose of this paper is to use PLC technology to analyze the automation application of electrical engineering, analyze the current problems, and analyze the system control application according to the characteristics of PLC technology. Experiments show that the leveling error is less than 0.5 degrees, and the longest leveling time will not exceed three minutes.
