The Design and Research of Electric Automation Control System Based on PLC

Abstract

In recent years, programmable logic controller (PLC), a new technology for electrical control, has developed rapidly and has been widely used in various production processes and automatic control of production machinery. It has the characteristics of convenient operation, simple and easy to understand, and high reliability,has become one of the most popular, most important, and most applied industrial control devices. It brings new vitality to power automation control technology, improves the efficiency of power work, and becomes one of the important pillars in the field of modern industrial automation control systems. This article aims to study the design of PLC-based electrical automation control system. Based on the analysis of the classification of PLC, the basic structure of PLC and the working principle of PLC, the PLC power automation control system is designed, and the system is simulated and tested. The test results show that the operation effect of the traditional electrical control system can not meet all the automatic working conditions, and the overall performance is poor, while the system in this paper performs well, indicating that the design of this paper is effective.
