Industrial automation system integration is an innovative industrial production solution. Specifically, it refers to a comprehensive technology that comprehensively applies control theory, electronic equipment, instrumentation, computer software and hardware technology, and other technologies to achieve detection, control, optimization, scheduling, management, and decision - making in the power generation process, aiming to increase power generation, improve the efficiency and quality of power generation production, reduce consumption, and ensure safety.

　　Fieldbus technology

　　Fieldbus is hailed as the computer local area network in the automation field. The rapid development of information technology has brought about changes in the structure of automation systems. As the industrial power grid becomes increasingly complex, people's requirements for the safety of the power grid are getting higher and higher. As an emerging control technology, fieldbus control technology will surely replace the past control methods and be applied in power automation.

　　Fieldbus has a very broad application prospect in power plants, substations, and power systems. Especially in new projects, it can obtain maximum benefits in many aspects such as reliability, high precision, and economy. The power system has always been a production department with the highest degree of automation. With the joint efforts of domestic and foreign fieldbus manufacturers and design and research departments, the control system based on fieldbus will gradually replace the existing distributed control systems in stages and by systems, and will surely become the leading equipment for power system automation in China in the future.

　　Sifang Company was the first in the world to apply LonWorks fieldbus technology to the substation integrated automation system and directly incorporate the microprocessor - based bay - level equipment into the LonWorks fieldbus. With its highly reliable performance and high - capacity and high - speed communication capabilities, it has greatly improved the information throughput and data processing capabilities of the communication system, thus solving the bottleneck phenomenon that often occurs when using low - speed serial communication to sample data. The LonWorks fieldbus network has strong anti - interference and anti - vibration capabilities, is suitable for a wide temperature range, and is suitable for the relatively harsh industrial environment of substations. Its transmission rate has far met the requirements of the substation integrated automation system for information transmission speed.

　　Wireless technology

　　Wireless communication technology has an attractive feature because it does not require complicated and expensive wiring within the factory area. On - site inspection and maintenance personnel can use it to maintain contact with control and management centers such as the central control room and achieve information sharing. In addition, wireless technology also has unique functions such as high flexibility, ease of use, and the ability to visualize, adjust parameters, and diagnose remote equipment or systems through remote links. The emergence and rapid progress of wireless technology are giving the power industry a new perspective to observe problems and are thus creating an exciting new era in the power process industry and asset management fields.
