Analysis and Study of the Application of Field Bus Technology in Conventional Nuclear Power Islands

To promote the intelligence and informatization of nuclear power equipment, the instrumentation and control (I&C) systems, which can be referred to as the "nervous system" of a nuclear power plant, need to adopt more advanced intelligent and digital technologies<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">[1]</sup>. This paper analyzes the technical features and application overview of fieldbus technology, summarizes several commonly used types of fieldbuses, and conducts a pros and cons analysis. It also proposes design schemes, ideas, and suggestions for the fieldbus design in the conventional island of nuclear power plants. It is hoped that this research will provide some inspiration and reference for the future design of fieldbus applications in the conventional island of nuclear power plants, laying a foundation for the fieldbus design in the conventional island of nuclear power plants <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">[2]</sup>.
