Preface

Electrical automation is a scientific discipline related to electrical engineering. China’s electrical automation control system has experienced decades of development. Compared with the earlier centralized control system, the distributed control system has the characteristics of reliability, real-time and expandability. The integrated control system makes more use of new science and technology and has more complete functions. Electrical automation control system has clear requirements for the efficiency and accuracy of information collection, and has a high requirement for the reliability and anti-interference of the automatic protection device. Electrical automation has the advantages of optimizing power supply design, improving equipment operation and utilization, and promoting the rational use of power resources.
        Electrical automation control technology is highly integrated by network communication technology, computer technology and electronic technology. Therefore, the technical coverage of this technology is relatively wide. At the same time, it also has a great dependence on its core technology - electronic technology. Only based on a variety of advanced technologies can it form an electrical automation control system with rich functions and stable operation. The electrical automation control system is combined with industrial production process equipment to realize production automation. Electrical automation control technology has higher accuracy in application, and it has the characteristics of fast signal transmission and fast response speed. If the electrical automation control system has fewer control objects and high equipment coordination in the operation stage, the automation degree of the whole industrial production process is relatively high, which also means that the quality of product under this process can be improved to a higher level. At present, the electrical automation control system is based on Internet technology and computer technology, which can realize the remote monitoring of industrial automation production line. The central control room can realize the monitoring of the operating status of each automated production line, and adjust its production parameters at any time according to the requirements of industrial production.
        Electrical automation control technology is composed of a variety of technologies. It is mainly based on computer technology, network technology and electronic technology, and highly integrates these three technologies. Therefore, electrical automation control technology requires a lot of technical support. In particular, there is a strong dependence on these three main technologies. Electric automation technology fully combines the advantages of various technologies to make the electric automation control system have more functions, so as to better serve the public. The electrical automation control system developed by the application of science and technology in many fields. Electrical automation control system can be connected with many devices, so as to control the working process of these devices. In practical application, electrical automation control technology has rapid response and strong control precision. In the new era, electrical automation control technology makes full use of the advantages of computer technology and Internet technology. It can also monitor the entire industrial production process and adjust production line data in time according to actual production needs.
